I have a question for the professor, "sir can u please tell me a chemical method for refining chromite ore and can i use aqua regia to refine chromite ore" Thank you
"Poor Neil's beaker caught fire. He should have known, perhaps, that it would, if he'd watched my video" I've never seen a smirk on this channel before today.
I find it very humbling and heartening that brilliant chemists and professors can still appreciate the beautiful sights and colors in chemistry. The math is one thing, but nature really can be beautiful.
Back in 60's when I was a kid (around 10 years old), my friends and I would ride our bikes to the drug store and buy bottles of ammonium dichromate. Big bottles of the stuff. After a few purchases, the pharmacist finally asked, “what in the world are you kids doing with all this ammonium dichromate anyway?” Oh, we're just making ammonium dichromate volcanos in our back yard. The pharmacist shrugged his shoulders, looked at us directly and warned us to be careful. We were careful and no one got hurt. And that how things went back the day for kids from Lake Wobegon.
Yea, The pharmacist that owned the pharmacy I did my residency at talked about all the cool things you used to be able to do. Mostly explosives. Until they cracked a window with their black powder, and his mum put a stop to it. We used to do random chemistry 'recipes' from the 18th century 'useful household things' ranging from fireworks to glue to pesticides.
Dichromate and Chromate (chrome 6) salts are also pretty toxic and highly carcinogenic. Just saying, probably not a bad thing that kids can't buy a drum of it from the corner store.
im from america and im 19 years old and ive been out of school for awhile and i just wanted to say i love your videos and that i continue to watch this videos to this day 4 years later. i love chemistry and i will continue ore videos as they come out. sincerely katherine
Oh gosh what great fun! As an aside "continually adding more ethanol" is pretty much my plan for the holidays; I hope you enjoy yours in whatever manner suits you!
I love it when the Professor gets to talk about his personal research. He’s got so many interesting stories. It’d be amazing to get some videos going into detail on some of his research projects he’s done.
I want to thank you for making these videos. Martyns personal experiences just add so much to these and make chemistry even more interesting. Wish i had this guy back in high school.
10:55 “When I was a schoolboy, [. . .].” It sparks in me a joy I can’t quite put into words that his awesome hair was EXACTLY the same at age 16 as it is now.
Actually, I'm pretty sure he'd want the professor to get it. On Hello Internet he was mentioning he hoped to get 1m subs for the professor's birthday, so a number of us Tim's came out to subscribe in support. He was also mentioning the plan to update all the older videos on elements, and that seemed pretty interesting too, so it's not necessarily just padding the numbers :P
You don't really learn anything from these videos. You have to have a basic understanding of whats going on to understand the reactions, enough to where you wouldn't be learning anything new, you'd just be seeing something happen that you already know will happen. If you don't know enough to understand the reactions, you won't know it from watching the video considering nothing about it is actually mentioned as these are beginner oriented novelty videos not educational videos, you'd need to spend a long time studying reaction pathways in an actual classroom before it could make any real sense.
556x45mm NATO, I think these videos are for people who know at the very least basic concepts. Also people who would like to learn about specific elements, and also basic chemistry of specific chemicals.
I love the addition of Martyn's childhood notes in the video! That was a nice thing to find and put together. I hope he wasn't digging through boxes in his garage for too long! Haha.
Today I finally finished my collection of stable elements. You totally inspired me to start my collection and it is truly fantastic and magical to have all the known elements here at home. Keep on inspiring people, best thing in the world!
I like the new Periodic Table of Videos. I am glad you decided to remake them. I am learning things I was supposed to learn in high school those many years ago.
Happy belated birthday, professor! What a video, I learned a lot, chemistry is a tough class but had awesome experiments-- so thanks for providing education and demonstration beyond what a standard lecture can provide! And congrats on 1M subscribers!
Watching your videos has led me to take up chemistry. I’ve always been interested, but never felt compelled to take the time and learn about the subject. Thanks for taking the time to make these videos. Hopefully soon I’ll be making some of my own.
I remember in my lab, chromic acid was used to convert secondary alcohols to ketones and primary alcohols to carboxylic acids. Pyridinium chlorochromate can convert primary alcohols to aldehydes.
Not to get off topic, but one of the coolest things I've seen so far on TH-cam, was from a channel called Thoisoi2. I absolutely love the channel, and he gets a hold of things like uranium, and plutonium, and does some amazing things. One of the best thing so far, was with alpha particles. Using an ethanol Cloud tank, he managed to get a hold of some thorium tungsten welding rods, and was actually able to show the world real alpha particles, in real time, being emitted from the thorium welding rods!!! The welding rods were the ones with no coating, and were, of course, Radioactive. I got to tell you, that really blew me away, to actually see actual radiation being emitted from something. It blows my mind. 🤯👍 could you imagine an ethanol tank, over the elephant's foot, at Chernobyl, back in the 90s?!?...😁
Merry Christmas all you one million people. Congrats The University of Nottingham chemistry lab. Get out of life what you put in. Amazing work, thank you guys and gals for the always intriguing videos. Peace on Earth :)
Funny I started watching this when I was a school boy ... now Im finished my first postgraduate degree and busy working on my first academic paper (In Computer Science but still ...). Ive always loved chemistry and this channel has been great!
😅 well I have a master's degree in computer science (finished this year) and worked for a startup that got acquired this year... Still no publications though ...
Really enjoy the refocus on updated/longer videos. Awesome not to just see energetic experiments ("yay, fire!"); but also to connect them to things like understanding how our perception of color can be affected by the energy level of electrons - well done!
Sir, thank you very much for your work and for sharing it. Honestly, when it comes about chemistry, my knowledge is very... very reduced. You have that flame of passion for your work... so contagious, that I am excited with each new episode you publish. The only think that angers me it's my limited knowledge. The same way I discovered astrophysics when I was a kid, when I read my first book of Hubert Reeves. Merry Christmas!
love this channel and your enthusiasm is contagious.. congratulations on 1mil subscribers, I don't know if we're here for the science or because of the professor.
Could you make a video explaining transitional metals? I know you are in the middle of your project to update your periodic table videos so I can wait. Cheers.
I could certainly use that video. I've been educated to a small extent on the elements and how they tend to generally react in the broad scope. I want to know what makes these sections of the table unique.
The simplest answer to why they are arranged in such a way is the valence shells of the elements. The s-block (groups I and II) have s-orbitals as their valence (outermost) shells, the p-block (main group) elements have p-orbitals as their valence shell, and transition metals have d-orbitals as their valence shells. The number of electrons that can go into the d-orbitals and their various energy levels are what cause them to have unique reactivity.
I remember being lectured by my chemistry teacher in 1975 about the dangers of forming compounds with the noble gases as the energy you put into it will be suddenly released all at once embedding fragments of the containing vessel into my body parts. The lecturing was done in the tone of putting objects into power points or playing with matches. I never forgot it. The lecturerer waved his arms around in an animated discussion.
Professor you are one of my heros! These videos have sparked my interest in science! I would love to meet you and just hear stories of interesting experiments you've done!
i love the fact that he refered to the gopro camera as being "not injured". so i now way with fully confidence that the gopro camera is my favorite character on the show
I like how he always has to “convince” Neil. I wonder if this an exaggeration or if Neil is just really skeptical like “Na. Sure it might explode, but like only a little.”
That laughter at 4:32 is haunting. If Neal* had another job he would be a Bond villain. *yes, I know, wrong spelling. But most descriptive of the man himself: noble, and oxidation makes him stronger.
That brings back memories from first semester. We had to do a lot of experiments and qualitive and quantitative analyses with cromate and dichromate. The experiments were really nice but we had a lot of chromate waste that we had to dispose properly. A pretty messy and slow process that blocked half of our fume cupboards and most of our beakers and funnels. Although the chemistry of chromium can be very beautiful and interessting, every time chromium compounds are mentioned a little alarm bell gets off ; )
I suggest maybe using some Bohr model diagrams for explaining the difference of colors, as well as the S, P and other orbitals in your videos. I think it would help the non-chem majors to understand a bit better. oh and hey happy birthday dude!
These videos are made by Brady Haran - check out his "Unmade Podcast" here: bit.ly/UnmadePlaylist
Ok thanks! I will definitely check it out🤯😌🙂🙃
I have a question for the professor, "sir can u please tell me a chemical method for refining chromite ore and can i use aqua regia to refine chromite ore" Thank you

"Poor Neil's beaker caught fire. He should have known, perhaps, that it would, if he'd watched my video"
I've never seen a smirk on this channel before today.
Maybe he should have warned him but that's no fun lol
I find it very humbling and heartening that brilliant chemists and professors can still appreciate the beautiful sights and colors in chemistry. The math is one thing, but nature really can be beautiful.
"... and the bottle says: CAREFUL, EXPLOSIVE.
So neil heated it"
Yeah. Loved this.
Lol, Neil's badass
"and the NSA says...." 😝
HAPPY BIRTHDAY PROFESSOR! WE LOVE YOU!
Is he 70 now?
Time to celebrate another solar orbit complete!
I'd love to do things this awesome at that age.
Belated birthday greetings Professor!
Is he 70 now?
Your enthusiasm for chemistry good sir makes me wish I had more teachers like you during my time at school!
Check out Wal Thornhill.
College and University teachers really care about what they teach and genuinely enjoy it. Other teachers could probably care less
@@LunaOfTheStarsMusicthat is a very general statement and definitely not the case everywhere

This is the most touching video of the whole series. Prof' Poliakoff's enthusiasm for his early research is wonderful.
sp3ccylad , I was thinking the same, but you put it best!
Every single video
“I persuaded Neil”
Im the guy who turned your 99 likes into 100
@Potato Servant dude your user name xD
I envision that every such persuasion has Prof Poliakoff speaking eloquently, and Neil just nodding and grunting.
And I'm the guy who turned your 199 likes to 200
Martha Kristiani I’m the guy who’s finding who asked

It's heartwarming to see the deep love that the Professor has for chemistry. Thank you.
i love how sir martyn always says "persuaded" neil. like you really need to persuade him to blow something up xD
Oh gosh what great fun! As an aside "continually adding more ethanol" is pretty much my plan for the holidays; I hope you enjoy yours in whatever manner suits you!
Well seems you and I have the same plan for the holidays. Cheers!
Jim! Is that why you have no videos? I subscribed to your channel! #14. Hee hee!
This really made me chuckle
So..
H-H
H-C-C-O-H = HO HO HO
H-H
I love this guy, he should have his own show. He explains things very well and has that personality for television.
Peter, Ditto on that. I wish I had the knowledge of the Professor & the others.
I love it when the Professor gets to talk about his personal research. He’s got so many interesting stories. It’d be amazing to get some videos going into detail on some of his research projects he’s done.

He already has number Phillie
I'm your fan for about 7 years from Azerbaijan Republic/Caucasus. You made me love chemistry.
Thank you, Professor! Thanks to all your staff!
This is one of the most valuable channels of the entire TH-cam world. I can not thank you enough.
This channel has taught me more than my actual chemistry teacher thx so much keep up the good work
Your cliche comment is cringier than Jake Paul!
Hartsock Thomson u try having my chemistry teacher for a term
U’ll see cringe
Hartsock Thomson, your reply was fairly lackluster. Improve your insults please.

Brady everything is looking crispy clear.
Well, as all the flames went onto the GoPro camera, that footage was especially "crispy", eh? ;)
Neil is the unsung hero of Periodic Tables....He should be aworded a gold Blue peter badge.
I could watch this genius all day.
I like the new Periodic Table of Videos. I am glad you decided to remake them. I am learning things I was supposed to learn in high school those many years ago.
There is nothing better than a unabashedly enthusiastic and passionate professor!
Neil always makes my day better.
Happy belated birthday, professor! What a video, I learned a lot, chemistry is a tough class but had awesome experiments-- so thanks for providing education and demonstration beyond what a standard lecture can provide! And congrats on 1M subscribers!
The best thing in Chem class EVER is when the teacher sets off the fire alarms!!!!

I am just embarking on science in a school setting, and I find this very fascinating! Thumbs up!
I really learn a lot from these videos. The prof really knows how to make chemistry understandable.
you have had an unimaginable effect on me for chemistry as well as many more people.t.y.
"I'm happy to report that our GoPro survived"
Prof. Poliakoff is just great xD
Just a marvelous project! I'm so glad you're putting the love and expertise into making this a more refined legacy for Periodic Videos.
What an honor and pleasure it would be to meet these wonderful people in person!
I always smile when I see a new video in my feed. These make me so happy!
Happy birthday to the professor, and congrats on 1 million subscribers! I'm really enjoying these updated videos. Great work!
Time to do my traditional 3 yearly binge of all Periodic Videos again, I think.
As always, Professor is making chemistry so much more interesting. Happy Birthday and all the best, Professor..!
I can listen to the professor all day. Thank you all :)
Congrats Brady & Professor Poliakoff. one million... Well deserved for much loved content :-)
I remember in my lab, chromic acid was used to convert secondary alcohols to ketones and primary alcohols to carboxylic acids. Pyridinium chlorochromate can convert primary alcohols to aldehydes.

This channel I'd wager to say is one of the very best out there.
you know these guys are partying hard when Neil almost catches fire.
Really enjoy the refocus on updated/longer videos. Awesome not to just see energetic experiments ("yay, fire!"); but also to connect them to things like understanding how our perception of color can be affected by the energy level of electrons - well done!
I just took my organic chemistry 1 final exam today. I used H2Cr2O7 to oxidize a primary alcohol group to a carboxylic acid in a synthesis problem!
"Neil nearly caught fire...."
Yep, it's Christmas
Literally first channel I subbed to years ago, SixtySymbols was #2, so happy for you that you passed a milli bud.

I don't understand anything that he is saying, but I watch just for the way he speaks, so satisfying.
As a young boy I never payed attention in school,especially in chemistry classes...But these videos keep me so focused on the subject :)
Yay early squad 🎆😎. Always a pleasure to see professor. Belated happy birthday professor from India.
Have a great birthday, Professor! Hope we can all celebrate many more with you!
I wish he was my chemistry teacher in school, he's so fun and fascinating to listen to
I would've become a chemist instead of a failure
Congrats on a million subscribers you guys deserve it
Chromium trioxide is so gorgeous! That color deep red! Very dark blood red, very reactive, with awesome flames. Wow.

I just love the professor like I don't get bored
One of the best and most fun videos on this channel. Well done! :)
Always great videos. Long live the professor.
Happy birthday professor🎂
That feeling when you're the safety officer and your subordinates don't turn off the fire alarm in the proper chamber.
I like how he always has to “convince” Neil. I wonder if this an exaggeration or if Neil is just really skeptical like “Na. Sure it might explode, but like only a little.”
I absolutely love this man with the scientist hair. I truly hope he’s happy and comfortable.
Love watching these videos!
How didnt more ppl notice this man is a youtuber
That laughter at 4:32 is haunting. If Neal* had another job he would be a Bond villain.

Neil's other job used to be being The Stig.
Eliphas Leary you deserve more than 1 like. So I'll give you another creating a fake account right now.
Hi👋
Hooray new video, Christmas saved after all.
Can we get an interview with Neil then?
I've watched 15 of these videos in a row.
Help me.
“Neil almost caught fire”
Neil: 😐🔥
Chromium, the rainbow element. I never knew that it is such a versatile and colorful element. Great video!
Always love watching these videos. I'd love to be at one of the Professor's lectures, seems like it'd be an amazing experience.
That brings back memories from first semester. We had to do a lot of experiments and qualitive and quantitative analyses with cromate and dichromate. The experiments were really nice but we had a lot of chromate waste that we had to dispose properly. A pretty messy and slow process that blocked half of our fume cupboards and most of our beakers and funnels. Although the chemistry of chromium can be very beautiful and interessting, every time chromium compounds are mentioned a little alarm bell gets off ; )

Congrats on making a million subscribers!
I wish i'd master chemistry just a little bit more so i could appreciate the world from another angle... love your videos !
No mention of the infamous "Institutional Green" paint that was used in just about every hospital, school, university, and sanitarium for 40+ years?
