  • I've read in other websites that Wöhler had actually separated yttrium from yttrium (III) chloride. Is this true?

  • he's leaning over, the fuking cables are holding him up. They did'nt go to the moon, NO WAY. Now how do I invest in itrium?

  • yittrum is classified as an "irregular lump"

  • someone give those sweedes some extra vowles for their names!

  • Astronaut 1 "It's all glass covered."

    Astronaut 2 "Why Glass?"

    Astronaut 1 "How the hell should I know?"

  • YBCO Is a super conductor at the high temperatures.

  • Metals are out to kill us. 8o

  • He probably means "Ytterby gruva", not "Ytterby groover", gruva is the Swedish word for mine. Great video!

  • "if it's really finely divided then it might burst into flames, in fact all metals if they're very finely divided they're quite likely to -er- spontaneously combust"

    So if you get some iron-filings and grind them down to make iron 'dust' will it ignite? I know he said all metals, I've just never heard about it.

    Finally... Why do all metals combust if they are finely divided?

  • hey i have been watching all your videos and they are great

    i always look forward to the alkali metals for that satisfying explosion

  • Ive never seen 2 people so fascinated by a rock,but they have purpose.

  • So, is Yttrium above Lutetium or lanthanium (or whatever it's called) in the periodic table when you put the actinides and lanthanides into the table itself (not below it)? I've seen versions with both.

  • what is Yttrbium?

  • That was pretty interesting.

    But there was no action.

  • Great Vid::

  • yay! brady will be using our class for an episode of the periodic table of videos!

  • I wanted to see it go on fire :(

  • Did he actually mean superconductors at 2:16, because i remember doing a superconduction experiment with Yttrium-Barium-Copper-Oxide to observe the Meissner effect.

  • ytterby looks like such a nice place

  • Indeed.

  • Quite so.

  • I love these videos. I like to learn something new every day...and these videos are awesome for that!

  • i have a friend in Sweden

    i'll have to send her this

  • Yeah, but he might need to send it in for further testing....just in case :D

  • Wait, did he say all metals can combust if split up finely?

  • That's what he said, I heard it.

  • The professor got a haircut?

  • How nice that they upload video where there's still snow on the ground. We haven't had snow here for the last 3 months.

  • it's from the Ytterby road trip

  • great!

  • quit the nonsense spamming

  • it burns? thats all i needed to know...

  • The Prof. had his hair cut.... i wonder if the cuttings are a new element..... :D

  • Where is Yttrium mined today?

    And is it evenly distributed or is it found only in certain places on earth?

    Great video,

    Thanks

  • Thanks.

    These videos have re-kindled my interest in Chemistry.

    (It was extinguished through 'having to' study it at uni, under a procession of very tedious and unenthusing lecturers.)

  • If you don't eat your meat, you can't have any pudding!!!

  • good song

  • The professor and his minions are breaking down the wall...

  • another great video :-)

  • epic
