Bismuth is great.
oh yes
It wouldn’t win in decaying any% though!
hmm yeah i wonder where that opinion came from
7 years ago???
🤘🏼
It is also used as a "lead free" alternative in hunting, using shot shells.
Wow this is so amazing!
The best thing about Bismuth is never having to say sorry! hahahahah!
***** I don't get it... :S
***** No. That's the best thing about being single.
@KatRaccoon Every good professor must have something they repeat.
A geology professor I had once said "It turns out" 35 times in a 50 minute lecture.
Yes. We counted.
tis nothing I had a lecturer that said "if thats all right with you" over 100 times (over 4 hours)
The scientist at around :30 kinda looks like one of those stereotypical mad scientists in my opinion...
Bismuth, the first non-toxic radioactive element that is an iridescent work of art.
+thebestofall007 Bismuth is not radioactive.
+Clyde Wary It's an alpha emitter, so it is radioactive.
Bismuth is slightly radioactive. Not many people know that.
Def Leppard Rocks That's understandable as it's half life is like 19×10^18 (2×10^18 more or 2×10^18 less)
iridescence just too gorgeous..!
Mind your own Bismuth
Hahahahahahalhaha Find the difference
I love it
Yes
Arthur Dent Steven fans joined the chat
are you Mike Tyson?
It's been years since I've seen this video. Coming back I expected a bunch of SU spam. I am disappointed in you guys.
'Tis shameful.
The edit history for the Wikipedia article is equally disappointing.
At least you would mind your own bismuth
Awesome! 5/5! I've always wondered about Bismuth... It does decay by Alpha decay, and is weakly radioactive. It's most stable and natural isotope is Bismuth-209, and therefore it will decay to Thallium-205 by 2.9x10^19, which is A VERY LONG Half-Life! It can be used to make crystals called Bismuth Germanate (BGO for short), which are used as scintillation crystals (colorless) , mainly to detect X-Rays, and will glow a bluish-green color under X-Radiation wavelengths. Keep Up The Good Work!
How's it goin
Oh
There should be a update on Bismuth.
I bet I could take a dump in the toilet, Pete would come in and look at it, and say "So, we have a lovely brown mass of fecal matter, just look at how it floats beautifully in the murky brown water...we have bits of toilet paper floating around it...they wiped quite nicely, you can see how the beautiful brown streaks contrast nicely with the white paper. Lovely! So, if we can fish it out of the water here we can take a closer look...oh look at how soft it is, the squishiness of it feels marvelous, oozing between my fingers. A really exquisite mass of fiber and bacteria I have here. We'll just put it back now into the water, see how wonderful the water splashes when we put it back. Amazing!!".
you are so disgusting.. 😂😂😂😂
This is the first comment that I am tempted to save a copy of.
I'm intrigued why did u write this comment
@@sabirinamdar6781 hes just being fecetious
He would 1st have a spool of stool wire 1st !
After the heat death of the universe, I'd like to imagine that all that remains is just chunks of the bismuth isotope floating around and nothing else.
But, then it wouldn't have reached heat-death because entropy is not at its maximum...
Heat death comes way after the half life cycle of bismuth.
@@uncommonsense360 there would be a little bit of it left
it may have a half life but you can devide by 2 more than once the thery may be possible
Kyle Lauzon Heat death is estimated to take place about 10^120 years from now. The half life of bismuth is 10^19 years, so that's about 10 googles of half lives, give or take a few orders of magnitude. After that amount of time, the odds of a single atom of bismuth remaining even in the entire universe is incredibly small. You'd be just as likely to randomly shuffle a deck of cards into perfect order by accident.
You forgot Schrödinger’s cats... they’ll all be floating around as they have from the beginning of time...
I'm a bit disappointed that they didn't demonstrate its diamagnetic properties.
***** this is a chemistry channel. they don't have to demonstrate elements' physical properties.
Stanley Li Yeah, but it's so cool.
+Lt. Daffy I bought some bismuth years back so I could see it's diamagnetic properties (which now that I think about it is kinda weird). Its definitely there, but it's a very weak property.
+Mike Bruhh nice bait
Lt. Daffy aren't like, most materials, slightly diamagnetic?
bismuth has to be my very favourite element. i love how dence it is but lead took the glory, how beautiful it is in pyrotechnics, and how beautifully mathmatic looking in its crystal form, with alll its right angles and majestic luster.
Was a little disappointed the 2nd version is also 12 years old!
Given the brilliant Bismuth crystal videos viralling around, would truly appreciate if the folks in Periodic Videos would consider making a third updated version.
Stay safe and healthy everyone!
Bismuth got a half life of billion times longer than the existance of the universe. So it is pretty much stable in my oppinion
I think the appropriate term is "stable enough".
SkeleBonePancake on 13/06/2018 this comment has 83 likes (atomic number of Bi)
I wouldn't be surprised if virtually every element decayed eventually
Very true 4quintillion years to be exact
Yeah. It is the least radioactive of all the 'radioactive' elements, which I don't think it should qualify as. The problem is, everything is radioactive once it's decay rate has been measured to a reliable degree. It is just that the the 'stable' elements are too stable to be able to do that... yet.
I would bet that your chance of getting cancer due to the radioactive decay of bismuth is non-existent compared to the heavy metal poisoning you would get from having the bismuth in direct contact with your skin for that long(since it only produces alpha radiation). A sheet of notebook paper is enough radiation shielding even if it was a trillion times more radioactive.
There's no Bismuth like show-Bismuth....*drops mic*
+Omnihil777
Thankgod, I thought he would never leave.
+Omnihil777 you should be ashamed of yourself
I'am sorry i don't get it

How 'bout this: "How To Succeed In Bismuth Without Really Trying"!
Video Quality 11 Years Ago:
Security Camera Quality Today:
Bismuth is also cool since it is part of a group of substances where the liquid phase is heavier than the solid phase (like water). Also pepto-bismol is pretty damn awesome when you have any kind of digestive problem XD
I want to go into chemistry, and I believe working with Bismuth seems interesting. Obviously, I have next to no knowledge on it, but the crystals are very pretty. I love your videos and I think that they are great for getting people interested in chemistry!
I was already interested in chemistry before this. If people need TH-cam videos to realise chemistry is amazing, then that's sad.
Well Debbie is pretty attractive so I do have a hard time focusing on the videos with her, let alone when the cameraman does something like that! >.
are u high?
It would be a nice idea to extend this video. Nano-particles of Bismuth show very strange behavour. Below perticle size of 9.2nm (can be made by a procipitation reaction from BiI3) it becomes a strong topological isolator - at room temperature to up to transition tamperature of 63.3°C. A layer with 1µm thickness can withstand a breakthrough voltage of up to 2'350 VDC and the Epsilon-r is about 4.2E6. Together with graphene as a electrodes, one could build capacitors with extremly high energy density. No binder is required, to form a capacitor, since Van-der Waals force is strong enough to keek two MgZn-electrodes in place. Additionally, such nano-bismuth belongs to the the most black materials. It even beats Vantablack.
Half life 3 confirmed
It's gonna take that long for it to ever be confirmed
3 billion*
Nope just vr half life
I looked bismuth up for Steven universe but this looks cool
I thought iridium was heavier? or Osmium.
Gen Scinmore wrong - even iodine is heavier than them
***** ty, I didn't know that.
Gen Scinmore I dont actually know for sure - im drunk
***** ah
Even as a troll I cant corrupt peoples minds
Another use for Bismuth (which might have originated after this video) is Bismuth based solder. It's quite common to make solder paste by alloying it with Tin. This will give you a lead-free solder which melts at around 140C, which means you can solder at much lower temperatures than usual (lead-based solder requires almost 200C and mainly tin-based solder requires almost 300C).
thank you, albert Einstein, very cool.
83 protons? Flippin heck that's heavy
Let's get down to Bismuth!
We're back in bismuth
Halflife the age of the universe hehe, never heard that before :)
I use a small percentage of Indium in my Bismuth crystals , seems to help with oxidisation
I just got a sample of bismuth for my collection, and so far, I have 13 of the 82 or so stable enough elements, I love your channel, keep up with the great videos
so , how's your collection now ??
You don't know your chemistry if you think there are 82 stable elements. If you consider all before bismuth(83) you'd think that it's 82 elements, but technetium(43) and promethium(61) are radioactive.
Bismuth is used in product called Pepto-Bismol which taken for upset stomachs.
Wait a second, there was no mention of Pepto-Bismol. Isn't that the main use in daily life?
W-what... WHERE IS ALL THE STEVEN UNIVERSE SPAM!?!?!? Dang guy's we gotta get down to bismuth...
I think shes lovely too
Great stuff! Science chicks are hot!
Debbie is lovely. I'm very impressed.
Let’s get down to bismuth! To defeat!
(Let’s make the whole song)
THE GEMS!
Brains AND beauty? I'm smitten, and I am not tslking about the blokes!
You didn't cover the use of bismuth as a gastrointestinal malady remedy? Pepto-Bismol is bismuth subsalicylate. (sp?) The crystals are damn BEAUTIFUL, I would be interested in buying a crystal.
Wow deleted Steven Universe episode
Video makes us want to chug down a bottle of Pepto-Bismuth! lol 😆
Much like you don't really meet with Jersey shore characters in real life, you don't have to meet an element in it's raw form to know what sort of Bonds it makes, and what reactions it takes part in, and what jobs it has for humans. So, The Professor is just.. as any scientist, really a master of one specific subdivision of a subdivision of chemistry. Him knowing so much about fields that are not his specialty is still a good bonus for the viewers, and probably when he's ''data-mining''
You forgot to mention field's metal, which is the non-toxic alternative to wood's metal that melts at a similar temperature, and is also made with bismuth.
en.wikipedia.org/wiki/Field%27s_metal
Great camera view!
Bismuth is the most naturally diamagnetic element. I also think it was the coolest looking crystals.
I was about to say that Bismuth was radioactive
Great playlist. I had a dream about making a series about all the element, but this is good.
@dushiemcbag science chick + british accent = killer
I was just wondering, for the purpose of curiousity, that since Bismuth (however minimal this may be) technically is mildly radioactive, what element then to this day is the next most dense material that is yet to be proven in any form radioactive?
Small formality: atomic mass is not directly related to density. Density often depends more on the structure of the crystal lattice. Osmium and Iridium are much more dense than bismuth despite having lighter nuclei, for example.
Lead 208 would be next in the line.
i have a bismuth rod which i found like when i was like 8 or 9 years old (i think it was a bismuth rod) i found it when i was walking home from the park near some place i think was under construction with all these moving trucks...
i think
Bismuth is my favorite element.
I wish I was made up of a rare isotope of Bismuth.
*****
It's a reference. The one who gets it will receive 1000 internets from me.
neil degrasse tyson
TheBball38
DING DING DING :D
Enjoy your internets sir.
I watched that video two
i like how the camera kept pointing at her chest. screw the bismuth right?
In machine shops they used to use a lubricant called white lead it is 90% lead oxide and 10% linseed oil. the lubricant was used for operations where the lubricant wouldn't squeeze out under pressure. so my question would be weather or not bismuth being less toxic than lead could replace lead in this compound.
+Joseph Eirman I'm not sure. I know that bismuth oxide is a powder like you'd need to mix the linseed oil, but I'm not sure how well it would lubricate machines compared to white lead. I'd say try it out if you could, but if it goes wrong that could turn out to be a pretty expensive experiment xD
bismuth and gravy
Debs is very cute. *.*
da fawq?
I find it very difficult to concentrate on the crystal in her hands...
she seems familiar, where might have I seen her?
There are so many atoms of Bismuth in a kilogram that I'm sure it is constantly giving off alpha particles even though it will take such a long time for it to decompose.
I once computed that a Pepto-Bismol tablet gives off an alpha particle every few months.
leave the guy alone, he said he was sure ;P who needs calculations when you can just guess.
Steven universe fan, it brought me here but...
It is a very pretty job, geology. It's so fancy
"...to make chemistry go a little bit more selectively." love that
not as much as cats and dogs and unfortunately not as much as you
"DID YOU *BISMUTH* ME?
I was looking for this comment!😀
I'm so happy for this video :D Pete being all warm with the metals, Deborah being all technical yet practical (which is awesome) and the prof.. Well, the prof is being the prof ; go figure :P
Bro what are you making?! Oh, I'm just cooking crystal.
Don't they put this stuff in Pepto-Bismol?
What happens to a bismuth crystal over a period of 2x10^19 years then? Because the thallium likely won't want to remain in the same crystal structure. So what happens to the crystal, assuming you could keep it from oxidizing among other problems.
I think this would be my mom’s favourite element😅
Yor mom's fave is my Bismuth Rod!
He needs safety glasses to remove a bismuth rod from a drawer. Hmmm..
it's Britain. He should also have had a hi-viz vest.
my favorite element because I'm Bi
There is another
same
I dont get it. Bismuth is less dense than lead and less dense than Iridium, osmium.. . so how can it be the heaviest non radioactive element?
The nuclei is heavier. There are more protons and neutrons in a bismuth atom. Iridium atoms are just tighter packed. Bismuth is radioactive becuse the atom is so large that it falls apart.
Cheers guys. We ordinary ppl think of weight differently :)
+King Théoden Bismuth has no strong van-der-waals forceses because the outer shell is nearly complete.
osmium and iridium have way higher forces because their d shell is around half full.
+King Théoden
Well, 'weight' is not a useful term here - it relates only to measuring masses in earth's gravity. Observing concentrations of _mass_ is more useful.
I thought it was because of the fact bismuth expands when it cools from liquid to solid, while lead contracts. This makes bismuth 'fluff' out in its solid form.
It takes a special person to make safety goggles look good...she pulls it off quite well
I understand Bismuth is less toxic than similar metals such as lead. However, could prolonged exposure to this harm you? I have searched and found little info on this matter.
(Looking for an alternative material for wedding band.)
I love the way these Chemistry types all mind their own bismuth....
my favourite element :D
The half life is indeed not only longer than the age of the universe, it's ore than a billion times longer
Given that bismuth is radioactive can we calculate a critical mass for it? Maybe the size of a few stars or black holes could cause criticality?
...Ain't nobody's Bismuth but my own... song needed.
I've noticed this subconsciously, but now I just chuckle every time because you are so right.
Hey guys, I've got a question for you. I personally like to play with bismuth and its crystal formations, but over time I've accumulated kind of allot of bismuth oxide that inevitably forms when you melt it down. I searched around, and supposedly if you heat up the bismuth oxide to the point that it melts, and have carbon in there, I'll get bismuth back as well as some carbon dioxide or monoxide (which one doesn't really matter to me, this will be done outside regardless). Does that sound about right to you? I know it's easier to simply buy more, but for the sake of chemistry I'd like to try it.
+The5thorseman It should work.
They didn't talk about Pepto bismol
IKR! Nile Red did a video on making Bismuth from that stuff
Blends well with the background
I love this show and all hail to Nottingham University
Bismuth is in fact a pretty element. Madame Debbie has caught my thoughts and eye with this one though. Excellent lecture and wish I could go to school there..
fla playa _''Madame Debbie has caught my thoughts _*_and eye_*_ with this one though.''_
Yeah, beautiful crystal isn't it? Think it was green or something...
meaturama Really? I'd be the star chemistry student and wouldn't worry too much about poor marks. lol
Bi does have an intriguing place in PT, the Pnictogens, insight about potential cmpd, complex, ore, alloy, salt, solution, potion, notion, & attraction beside some ways expected to behave like N although in our physical parameters Bi is a metal solid (as astute commenters noticed interesting physical characteristics happen during phase changes), +3 & +5 cations, relatively non-toxic, crystals provide fascinating art & medical apps with substances like BSS that in ways coat & protect stomach, even found effective for diagnose & alleviate GI illness, beside coat & preserve built structures. But must regard within physical & chemical parameters? The PT location is very intriguing transition area despite it's seemingly indifferent or dubious organic use still forms oxides, sulfides, carbonates, & involved with the already mentioned BSS.
"Not very poisonous"
its radioactivity was discovered in 2003, but it have extremely long half-life, 19 quintillion years, even a huge amount of it is not dangerous
_Ayyyyyy_ 😘
Bismuth is no longer the heaviest non radioactive element. Lead is "RIP Bismuth 2008"
Woods' metal is used for safety-plugging pressurised gas canisters so that if they should encounter fire, they will vent rather than explode. Which really has a very spectacular effect if the gas within the canister happens to be oxygen. 22 litres of O2 at 2000 psi, suddenly added to a fire, will take it from "minor localised fire" to "house fully involved" in about 30 seconds. No, really, I've seen this happen once, it was very dramatic and rather startling even to the firefighters who didn't dare enter the house because they knew the canister was in there.
Bismuth is the heaviest non-radioactive element because one mole = 208.98040 grams.
If you had a 1,000 mole (209 kilogram) lump of pure Bi-209, only one atom on average would decay per second.
Awesome vid, practice with manual focusing of the camera, it'll do wonders for focusing in on little things!
science chicks are cool man
We mean Bismuth
Can't tell if this video is a troll or not... Bismuth rod guy cracks me up...
