I got the chemistry bug from reading "the discovery of the elements" when I was 14. One chapter that I loved was the heroic story of the discovery of the rare earths, including the four named after one Swedish village, Ytterby.

That always fascinated me in chemistry how it was determined and what it meant for gas chemistry. The mole always seemed such an arbitrary and magical value!
Would it be fair to say that terrestrial helium is all formed from alpha particles emanating from the radioactive decay of uranium and similar elements or is there some other source of helium on earth?

Most "neon" signs DO NOT contain neon. Only the red ones that are transparent when turned off are neon. The rest are fluorescent lamps, filled with argon & mercury to make UV light, & a chalk-like phosphor coating on the inside of the tube. When those are turned off, they look chalky-white (unless the glass tubing is itself colored).
As far as I know it's not even the color of the power that makes the light turn color. I think the UV light hits the powder and is refracted into the visible light spectrum, depending on what you use you can get different refraction effects from shining UV light onto the powder
@@jllemin4 It is not refraction. (Refraction only changes the direction of light, not the wavelength.) It is fluorescence. In fluorescence, the atoms of the powder absorb light, exciting their electrons into upper atomic orbitals. When these "fall back", they release light. Since the distance they fall back to is less then the upward kick they got from the incoming light, the result is light of a longer wavelength. So UV from the mercury in the discharge excites the powder ("phosphor") & the phosphor emits light in the visible (longer wavelength then the UV light). The chemical makeup of the phosphor determines what color you get. (The color of the fluorescence is usually not the color of the powder when viewed under white light.) In real neon lamps, the light you see is directly emitted from the ionized neon. Other colors are not done this way because the efficiency of other direct visible colors from ionized gasses is poor compared with the mercury UV output to phosphor to get visible light.
If i remember correct. First color tubes (Gas-discharge lamps) use different gases to produce color. Neon is red, argon deep pink or light purple (similar color to nitrogen) , add sodium and we have yellow. Fluorescent lamps are mercury vapor lamps using phosphorus coating. Mixing different fluorescent minerals or simple pigments or even top coating create color.
I'm quite surprised, and impressed, that 19th century scientists could reliably measure a 0.5% difference in density of different gas mixtures. What method did they use?
well in science class we are told to repeat the experiments multiple times and the school equipment of nowdays are very low quality back in the day the actual scientists had super precise measuring methods which were still taught (tho our error rates are much more due to the equipment) its not a suprise he was able to measure such a diffrence especially as a chemist
@@vijayvijay4123 Raman scattering involves a change in wavelength of the scattered light, whereas Rayleigh scattering does not: they are completely different physical processes.
Amazing video and superb historical research. If you think about that these scientists worked ages ago under rather simple conditions and with barely analytical instruments: That is really genius :)
In most cases they had to make their own experimental equipment. (I'm thinking of Cavendish and the equipment for his gravitational constant experiment)
I find it amazing that Ramsey had a role in the discovery of or identification all the noble gases except for oganesson (which may not be a gas at all). Apparently the reason radon was accepted as the name for element 86 was that radium emanation (radon) was the longest-lived isotope. Travers didn't share the Nobel prize in Chemistry with Ramsey, but nowadays he might have, though Ramsey was unquestionably the driving force. Except for argon, where he and Lord Raleigh share the honors. I still saw niton as the name for element 86 when I was a kid. By the way, Ramsey asked his son for a name for element 10, and his son suggested novum. Ramsey turned it into Greek to match argon and krypton, so neon was born.
I'd like to see a sequel about the history (and associated accidents) of isolating fluorine. The most reactive element. A lot of brilliant people lost part or all of their vision, among other things, in the pursuit of isolated diatomic fluorine.
I first came across Ramsay's name when I studied at Glasgow University in Scotland - all these wonderful buildings named after their famous alumni; Lord Kelvin, Adam Smith, James Watt, John Logie Baird, Joseph Black, Colin Maclaurin, David Livingstone, Joseph Lister...a wonderful era of discovery.

Hello, being a chemist myself I can apprechiate the work you did to unfold the history of this Elements. A good tale might be the discovery and separation of the Lanthinides, done mostly by extremely careful gravimetry around the 1920 (if I remember correctly). There is probably no living chemist around, who could nowadays do gravimetry with that precision as we now rely on other modern tools. Another gravimetry problem: Proof that the Lead from the different decay-chains has different weight, also confirming the decay-chains.
This video was spectacular in every respect. The science history was excellent but I particularly appreciate the detailed treatment of word origins and naming conventions that invites those with other backgrounds to appreciate the ideas a bit more. 😊

As a Polish speaker, I pay my respects to you because of 8:16 (and onward). You pronounce both names VERY well, which is extremely rare for English speakers - and not because "Polish is hard". People practically always just replace all Polish letters ó, ł, ń, ą, ę, etc. with English letters that LOOK similar (o, l, n, a, e) and then just read everything in English, which makes absolutely no sense (visual similarity or even identicality of the Latin letters between languages has nothing to do with the similarity of how they sound in those languages). Often such inter-linguistic caricatures cause only laughter. Sometimes, however (e.g. in the case of names!) they cause a sense of disrespect. Thank you!

Imagine where the world would be without Argon, Literally almost everything today uses Argon to some extent in manufacturing, Any metal-working involving aluminum, stainless steel, or titanium requires Argon as a shielding gas. It's used to purge vapor deposition chambers for making ICs. It's used for sputtering. It really has became one of those chemicals, like petroleum products, or sulfuric acid, that's just used for everything.
As someone who didn't study science much in school, and has since come to really appreciate chemistry, I particularly enjoyed this. Really neat story, very well told.
Large amounts of argon are used in welding in order to provide a protective atmosphere that excludes oxygen and nitrogen and prevents them from reacting from the hot and molten metal.
Really enjoyed the video! I only knew a little of this previously - it was great to have the full picture and the logical path Ramsey took to isolate the new gasses. It's truly amazing to follow this line of thought - when laid down like this it's logical but for him it would have been treading on new ground, as profound as the guy who stood looking at geological folds in various rocks and first realising how deep time actually was - from the 10,000 years of history he'd been told about to realising this would take hundreds of millions of years to form.
Absolutely fantastic video! Very informative especially concerning the order of discovery. Also wonderful descriptions of the experimental techniques used to isolate the gases. Clearly they has some very good analytical techniques back in the day.
This is amazing. From back when an insistence that others ‘‘Trust the science’ without a corresponding paper trail would’ve seen you heckled by passers-by as you strolled the streets of Prague.
This is an excellent video. Very well done. It always amazed me how the hell these early chemists managed to work with such tiny amounts of invisible gases without losing them in tubes and pumps. They obviously cooperated with skillful flameworkers (which were, back then, a staple of universities' laboratories) and even had such skills themselves. One thing I've never seen anywhere in literature or online, is condensed radon, liquid or solid. It's a fantastically radioactive substance and something tells me it is very well possible nobody extracted and condensed enough of it to show radioluminescence in bulk after first characterization was made. Afterall, it's a very dangerous procedure and today it would be so expensive to do, without enough cost return. :/
Love your video. I’m a retired chemist and have always been fascinated by the multiple elements named after the small Swedish village of Ytterby. Possible video?
Since I've known the basic chemistry involved since childhood. It was good to fill in the history. The last half of the 19th century was a golden age for discovering elements. Very articulate well-presented and definitely kept my attention throughout. Thank you.
Another fantastic video! I teach chemistry but with a background not strictly chemistry oriented and your videos give such a rich background and insight to the basic curriculum. So thank you! I would love to see a video on the halogens or group 1 metals at some point.
Imagine discovering the air is made up of multiple gases. That would be so cool. Imagine telling your friends "yo, I think the air is a mixture of gases." "What? That's crazy"
I dont often find new channels to like and subscribe to. Thank you for your efforts, in the days when your up in the multiple 100k subscribers, I think going through each element in a seperate video would be fascinating. A great compendium to the table.
That was so much fun to listen to. And putting it all in one video helps connect it so nicely. I assume there are so many many details implied by a statement like carefully doing fractional distillation over 2 weeks. It must have been very exciting for them.

It's truly amazing to follow this line of thought - when laid down like this it's logical but for him it would have been treading on new ground, as profound as the guy who stood looking at geological folds in various rocks and first realising how deep time actually was - from the 10,000 years of history he'd been told about to realising this would take hundreds of millions of years to form.
That was incredibly absorbing. Thank you.
What an incredible accomplishment! We definitely take for granted such basic research nowadays. Thanks for your excellent presentation! Cheers!
Absolutely fantastic video! Very informative especially concerning the order of discovery. Also wonderful descriptions of the experimental techniques used to isolate the gases. Clearly they has some very good analytical techniques back in the day.
This is amazing.
From back when an insistence that others ‘‘Trust the science’ without a corresponding paper trail would’ve seen you heckled by passers-by as you strolled the streets of Prague.
Thank you for a really interesting video, especially given that you show how the scientists provided evidence for their claims, so often skimmed over.
This is an excellent video. Very well done.
It always amazed me how the hell these early chemists managed to work with such tiny amounts of invisible gases without losing them in tubes and pumps. They obviously cooperated with skillful flameworkers (which were, back then, a staple of universities' laboratories) and even had such skills themselves.
One thing I've never seen anywhere in literature or online, is condensed radon, liquid or solid. It's a fantastically radioactive substance and something tells me it is very well possible nobody extracted and condensed enough of it to show radioluminescence in bulk after first characterization was made. Afterall, it's a very dangerous procedure and today it would be so expensive to do, without enough cost return. :/
This was amazing and delightful-- Every Chem student should watch this to understand the process of discovery-
I love this video. The way they used to work things out without a computer using contraptions, math(amatic)s, pen and paper. amazes me.
I loved the video. This period of scientific history is so fascinating.
Love your video. I’m a retired chemist and have always been fascinated by the multiple elements named after the small Swedish village of Ytterby. Possible video?
This was really cool to watch, and informative. Thank you!
Since I've known the basic chemistry involved since childhood. It was good to fill in the history. The last half of the 19th century was a golden age for discovering elements. Very articulate well-presented and definitely kept my attention throughout. Thank you.
Another fantastic video! I teach chemistry but with a background not strictly chemistry oriented and your videos give such a rich background and insight to the basic curriculum. So thank you!
I would love to see a video on the halogens or group 1 metals at some point.
Imagine discovering the air is made up of multiple gases. That would be so cool. Imagine telling your friends "yo, I think the air is a mixture of gases." "What? That's crazy"
🤯
Lol what's next, rocks falling from the sky? Giant space whales living within moons of Saturn? Get outta here
you're so thorough wth your research - keep it up, I really enjoy your vids :)
I dont often find new channels to like and subscribe to. Thank you for your efforts, in the days when your up in the multiple 100k subscribers, I think going through each element in a seperate video would be fascinating. A great compendium to the table.
Very good coverage of a great subject; quite a nice survey. The entire video was well produced and had good timing, thank you.
amazing work! I was always curious how they found inert elements experimentally i always heard about helium but this puts it all in perspective
The irony of radon _treating_ cancer...
"discovered by myself" is such a well earned flex lol, huge props
That was so much fun to listen to. And putting it all in one video helps connect it so nicely.
I assume there are so many many details implied by a statement like carefully doing fractional distillation over 2 weeks. It must have been very exciting for them.
what a great video man! fantastically written script regarding storytelling and great on the technical and informative side, too ♥ as a huge fan of chemistry and an amateur chemist I am happy I discovered this channel
@Chemistorian I just discovered this channel, this is the first video i've watched and I must saw it a splendid video. I see myself watching more of your content. Chemistry experiments and the history of them are both important concepts that need to be shared. Keep up the good work.
Thank you for your effort and your time.❤
This was an awesome history lesson.
amazing video! It's crazy to me just over 100 years ago we didn't know shit about some of the elements that our modern-day society has become so accustomed to.
what an amazing history video, thank you for making it :D
What an enjoyable video! I'm shocked I hadn't chanced upon your channel previously, but I have your previous videos to catch up on, so I won't be too sad about it.
I love to understand how things work, but need more channels like this, about the historic development of Science research and Engineering.
Another high quality video!
wow this is a beautifully produced video keep it up!
these stories leave me with sparkling good vibes. :)
Excellent presentation: subscribed!
Very nice work, informative and engaging, without any hype - thanks. I like chemistry but I was a bit rubbish at it - went for physics. Subbed.
Very well told story! This is how it should be done in schools! 🙏
Just subscribed! 😎🇩🇪
First video of yours I came across, absolutely amazing! Surely will watch many more of your vids
This is very intriguing and interesting id love to get a video of the lore(history and random info abot it) of each element. I just think it woukd be very useful to have all info in one place :D
I love videos like this about chemistry and history, please keep making them :)
amazing, soma get chills.
A wonderful presentation of a novel subject 😃🧪
Thanks algorithym for showing me a great channel, you have my follow. We need more youtubers talking about Chemistry history
Muchas gracias!
Here again you provide an ideal support for my teaching of the discovery of atoms and chemical elements. Thank !
Very nicely done. May your channel grow to what it well deserves to be!
you don't have an @ ?
@@redmadness265 I don't know what you mean
All other channels I've seen have an @ even mine, but not yours and it looks really weird
@@redmadness265 still a mystery to me what you're on about, mate.. I see no @ that isn't there.. 🤪
@@redmadness265 I've finally figured out what you meant. . yeah, it's kinda odd. Can't say I remember seeing it elsewhere either..
let's have a lookaround
More people need to sub to this guy.
Nice Piece of Work!
My grandfathers 4 older brothers made the first X-Ray tubes in the UK and died of radiation poisoning. They were a firm of glass blowers Tony Aimer Johannesburg
Argon is also an important industrial gas used, among other things for welding.
I am teaching the history of science to middle schoolers and your channel has just become a wonderful resource, thank you for all this hard work, subscribed!
I think it was Rutherford who called chemistry “stamp collecting” - but if so, these are incredibly interesting stamps. Fabulous video. Well done.
so clear, thank you
Best, most informative YT video I've encountered in days! Thanks for the (historic) memories.
Leaves out only Oganesson, discovered only this century, by very different means, and very short-lived, radioactively.
I'm guessing that, were you to cover its discovery, it would be as the culmination of a series on the synthesis of the transuranic elements?
Fred
Great video! HIGHLY informative and very detailed.
Loved the presentation!!!
Thoroughly enjoyable! Crazy to think of the sheer effort that went into these discoveries. One of those efforts would have to be overcoming repeated disappointments!
I enjoyed this video. Very interesting. Thanks.
Human collective knowledge through rigorous testing and experimentation of past humans are so incredibly inspiring to think about!
Great video!
Thank you!
Amazing video! I always thought neon lights were special... you made them even more special
Fascinating video. Well done!
One of the best videos I’ve watched. Thank you sir.
Thank you! Fantastic video!
"no matter what he did, the atomspheric nitrogen remained 1/2 a percent denser than the chemical nitrogen"
Lol, I like how this reads like a line from a classic fairytale. Just an exceptionally boring one to people who need drama and action to be entertained XD
Great video!
This video is very well done. It should be required viewing as an introduction to chemistry and the scientific method. I am looking forward to more videos like this. May your efforts be appreciated and rewarded. Thank you.
