Fluorine can also 'oxidise' oxygen, the only element which can. Oxygen itself is a vicious element already, easily oxidises chlorine, right the way to perchlorate.

[@andygrove285]

​@@Paonporteur You are incorrect my friend. There is an entire series of halogen oxides (excluding fluorine). For example chlorine dioxide used to disinfect water, and also corresponding chlorine oxyacids and ionic compounds of them, for example perchloric acid and potassium perchlorate. And, there is a series of oxygen fluorides, for example dioxygen difluoride. Also take a look at compounds like perchloryl fluoride and nitryl fluoride for even more wackiness. A simple look at the Periodic Table will explain what is and isn't possible in terms of what can oxidise what. I think you are talking about 02, dioxygen, which is already reacted - with itself, as I mentioned in my first comment.

[@hungarianheroes]

​@@andygrove285 Things doesn't work this simple Just because a compound exists it doesn't mean you can synthesize it from its constituent elements. For example Ag2O, Au2O3 and HgO all exists, but still, you can't make them by burning the corresponding metal. The same is true for a lot of halogene oxides. (Also F2 only reacts with O2 using an electric discharge, so I wouldn't call it a simple oxidation.) Also checking the ptable for electronegativities won't tell you everything about an element's reactivity.

[@andygrove285]

​@@hungarianheroes What are you talking about? Can fluorine oxidise oxygen? The answer is yes. Can oxygen oxidise halogens, except fluorine - again yes. Please take time to read my comments. I said nothing about direct synthesis or any method of preparation. Furthermore, you are considering molecular dioxgen, so your logic is flawed anyway. It seems yourself and our friend @Sweet bromine are considering oxidation in layman's terms, meaning like element/compound X reacts with oxygen to produce an oxide. In chemistry terms, oxidation is the process whereby an atom, ion or molecule loses electrons. Fluorine can pull an electron from just about any other element, even oxygen. Oxygen can pull electrons from just about any other element, except fluorine. There may be other bizarre cases, such as excimers or something, but, at STP it's generally true. Of course, the noble gases are extremely difficult, or impossible to oxidise due to their electronic stability. However, xenon fluorides do exist for example.

[@hungarianheroes]

@@andygrove285 From your original comment: "Oxygen itself is a vicious element already, " - looks like you as well meant elemental oxygen. After that it was normal from sweetbromine and myself to assume that you really ARE talking about dioxygen. And thanks, I was not in need of this additional explanation about how redox reactions work.

[@andygrove285]

​@@hungarianheroes It's pretty clear what I meant when I mentioned perchlorate. If yourself and sweetbromine tend to take the naive view of that, it's not really my fault. And, once again, it seems pretty clear that both yourself and sweetbromine are considering plain, chemistry 101 reactions with molecular oxygen which is itself a compound. In any case, I hope the situation is now clear.

1:16 Haha, the fluorine gas he can't see is inside tubing that's made from a fluorinated polymer that he can see. It's interesting that Teflon, FEP & PFA are the best plastics for chemically inert tubing;they're all fluorinated polymers formulated with the most reactive element. Go figure!

[@miikkasilfverberg2303]

Wouldn't it make sense that the most reactive elements give the most stable (inert) compounds? :)

[@SIMKINETICS]

Miikka Silfverberg Yes, but the first impression seems ironic or counter-intuitive unless one knows about chemistry. I'm a retired engineer whose last project was to re-design a specialized electroplating instrument that was being destroyed by a wide variety of very harsh chemistry used for electroplating several metals, including platinum, gold, iridium, nickel, zinc, titanium & others. The project was challenging because nearly all the working parts, including high & low voltage electronics, structures, containers, valves, pressure/vacuum controls, which had to be replaced with mostly teflon-coated components, platinum or 316 stainless. Then, there were gobs of tubing & fittings to replace (all FEP, PEEK or teflon). Chemistry run through it included concentrated acids & bases at both ends of the PH scale, bleach, hydrogen peroxide and piranha. Lots of pricey, specialized labware were required. Although I had worked with many chemists for decades, that final project really got me thinking about & researching inert materials. Chemistry was never my strong suit, so it was an education for me. Generally, I've got to say that automating chemistry processes was very interesting work, and direly needed to keep PhD lab-rats from becoming disenchanted with the tedium in their lab work. I'd recommend to engineering students that they get a good dose of chemistry & really learn it well because the demand for engineers will focus in that professional arena and other scientific endeavors involving chemistry as part of a process. Increasingly, engineering is becoming mostly scientific.

[@miikkasilfverberg2303]

***** I'm absoutely not competent to discuss this matter :) but that sounds interesting! Do you know of any articles that someone with a high school background in chemistry can understand? I read an article on Wikipedia (en.wikipedia.org/wiki/Bioenhancer) but that seemed a bit sketchy. Maybe you meant something else?

[@miikkasilfverberg2303]

***** Thank you! :) I found this very interesting! Cool that changing one atom can have such an effect! Nevertheless, this was not an easy read with my chemistry background... So what I'm going to say may be total garbage :D As far as I could understand, they present several reasons why fluorination could be useful in increasing bio-availability. Stability is one of them. In Section 2, they seem to explain how increased stability of the fluorinated compounds increases bio-availability: it makes them more resistant to metabolic enzymes and thus more likely to reach the site where they can be medically active. However, as far as I understood, they also say fluorination can modify the basicity or acidity of parts of the compound, increase binding affinity to proteins and change the form of the compound (or rather the preference between different isomers of the molecule). A lot of factors besides stability are at play apparently! Both properties of fluorine itself and properties of the target protein factor in. The combination of biology and chemistry is really interesting! Though it also seems quite tricky :)

@@potatoboy549 The only reason oxygen isn't that reactive is because in it form O2, it is actually pretty stable. Now, took oxygen in other form, and all of them are extremely reactive. For example : O3, HClO, NaClO,etc. HClO--> HCl + O, and the O atom are extremely reactive, maybe (nearly) as reactive as flourine.

[@potatoboy549]

Well, if every element was in its atomic form they would be quite reactive. For example Nitrogen is extremely tame but in atomic form it would tear everything apart. Not just oxygen. But if that happened, fluorine would still be on top and all the halogens would be leads more reactive than oxygen.

[@rohanb.k3620]

There's already a video about that recation

[@mezzanoon]

This is an amazing video, well deserving of an update

[@blindandwatching]

They drop alkaline metals into water. How about sodium metal having this flourine rig hit a target of caesium or potassium instead of steel wool or sulphur?

[@denelson83]

The Royal Institution posted a video of CsF being produced.

[@visioneerone]

I never knew how fluoride worked to slow down tooth decay. I have learned something new today. That being said - I cannot stop watching your hand motions during the interview segments.

[@shamdak2]

If the professor fixes his hair, he will resemble Michael Douglas!

[@nosuchthing8]

no, hes perfect

[@LillianWinterAnimations]

If Micheal Douglas sciences his hair, he will look like the professor.

[@edwardbarry877]

how does it react with argon?? or any other inert gas? (which isn't helium or neon - the ones that were listed)

[@MrMad1940]

+Edward Barry they can be forced to react, I believe by having the electrons forced into the reaction or something (cant remember what my chem teacher said)

[@aznboy131]

+Edward Barry Think it forms a hexafluoride in all cases. One of my classmates in undergrad gave a little presentation on noble gas compounds, and if memory serves me correctly he said XeF6 was the first one isolated at room temp. Based on the directionality of the trend, I'd imagine noble gases from argon on down are capable of reacting with fluorine simply bc of more electron shielding.

TheRecreator Why hey there beautiful

[@TheNadude]

It was much more exciting than I thought! You could see the flames

[@EpochRazael]

Here I was thinking that oxygen was the best element to use for oxygenation. Fluorine is so much better.

[@JackOSergius]

I think you meant "oxidation"... And, if that's the case, check out krypton difluoride (KrF2) Now that's an oxidiser!

[@nella1033]

1:00 Would anyone know where we could buy this kind of periodic table?

[@nialbradburn3851]

love these videos -they have reignited my love of chemistry (no pun intended)

[@trustthewater]

I am so happy to see this! I had a junked excimer laser that was being scrapped for parts/metal and when I found out they use fluorine in them I was scared to take it apart. Thankfully it was empty, but this video helps illustrate why I wasn't wanting to mess with it. I feel vindicated!

[@fluffernutter03]

@StarSpawn06 well at some point they do pass it through a plastic tube actually, in the beginning when they freeze it, but i have absolutely no idea why it doesnt react with it, or maybe it does react, just really really slowly? dont know lol

[@amorphusensanity]

from what I've heard, it's rather amazing he still has all his fingers and both eyes.

[@gnarlyDUCK]

All I needed to hear was a proper explanation given at @5:15 makes the whole toothpaste debate make more sense.

[@dielaughing73]

What debate?

[@sirdude2220]

What a terrific element! It's truly emotional for me to see this video of such an amazing element as Fluorine.

[@HayaJi]

What a cool element! Thank you!

[@udyrfrykte420]

Another video is the "Toast to Tony" video, where Professor Poliakoff toasts to the life of his friend, who also struggled to see the usefulness of this element. His outlook on the "domestication" of fluorine is really quite helpful in understanding fluorine versus fluoride. Plus the video might just make you cry, it is really quite touching.

[@Evolved_Skeptic]

Amazing. This is incredibly fascinating. I recall many years ago, when the *Alien* series of movies first came out, that people were looking for an equivalent to the fantasy super-acid of *Alien blood* & someone suggested the real super-acid *_Fluoroantimonic Acid_* ( *HSbF6* ) - which is terrifyingly corrosive.

[@somethingsomething404]

his face as he realized that the camera guy was promoting him to explain fluoride vs Florine was hilarious, he’s like “Florine in your what! Don’t be silly... Oh! that’s what you meant, Fluoride”

[@PubliosValesios]

Thank you for this video because for the first time I saw liquid fluorine gas and learned interesting informations about the flourine element. Congratulations !

[@Sep3lio]

Damn. We learned a bit of fluorine chemistry in our inorganic class but this really puts just how reactive it is in perspective.

[@golf-n-guns]

Incredibly informative and interesting! Bravo! Fluorine is to be respected!

[@Restilia_ch]

My favourite fluorine compound is also one of the most dangerous substances on the planet with a practical use: chlorine trifluoride. It will set fire to pretty much anything, including bricks, leather, glass, most metals and ASBESTOS.

[@TariosGD]

Elemental flourine can probably do a lot of that too

[@zezo69]

the way that professor talks, it cracks me up

[@sk8erguy552]

Was the screen saver changed the in the background of the video or something? 6:05

[@RH-xs8gz]

What is the inside of the canister of fluorine lined with? Some type of fluoropolymer?

[@theyoten1613]

Nickel Fluoride, When nickel rusts it forms oxides, or fluorides in this example and those don't react with the other fluorine, forming a protective lining. He says this in the video.

[@sphinxracer]

as a welder i use an oxy-acetalyne torch. could flourine be used to cut steel? i think if so it would be awsome never having to light the torch. but then again it reacts to so much you would have to be very safe and point it only where needed. how costly is this stuff

[@midge158158]

It's great that even the Prof. experiences new things because of this amazing project!

[@leptonsoup337]

Thank you for that! That was quite interesting. I'd would really like to see and hear more about fluorine chemistry since it is one of those areas that I left unexplored.

[@odiac1737]

Were the experiments really done without special ventilation of the area?
