The Most Massive Molecule - Periodic Table of Videos

The theoretical molecule Oganesson Tetratennesside is the largest possible with five atoms - but is it possible!?

That's a lot of electrons, and computing them respecting quantum and relativistic effects is a mind-boggling achievement!

No one has made OgTs4, but I believe it tastes like chicken

It's such a small observation from the video, but apparently elements 117 and 118 have been named since I took chemistry in high school. Back in 2015, I remember them being referred to as the placeholders ununseptium and ununoctium. That's kinda cool.

2:36 Thought there was a typo, but apparently it's true that Tennessine and Oganesson have the same "mass number", 294.

So happy to see the prof back in the office! And he's back with the video I love the most: hypothetical and exotic chemistry

[funguy]

I love it when he brings out the dog toys to explain molecule shapes

[rayoflight]

A very, very interesting molecule.
Always a pleasure to hear and see Prof. Polyakoff.

I've really enjoyed professor P's enthusiasm for chemistry thru the years in his appearances. Very knowledgeable on a wide range of processes. Thank you sir.

As interesting as this molecule appears to be, I would love to see Helium Hydride 😬

[AlRoderick]

Tetratenniside sounds like the charge levied against a ball boy who takes out a whole doubles match in one go.

im so glad a brilliant man of wisdom and education, who is seemingly a kind and patient human being and extraordinarily well spoken, has the oppurtunity to have these moments of teaching shared in this format.

[scruffyishmarr]

Good to see you are doing well professor

When I first saw the thumbnail, I nearly thought it was Tellurium tetraiodide for some reason...
This is such an interesting video, showing the power of computational chemistry.
It does made me think of a question though: what is the most massive, stable 5-atom molecule that can be synthesized in a normal (i.e. non-nuclear) lab?
The best I can find is the monomer of platinum tetraiodide, with molecular mass of 702.7 AMU.

Last week we started an entry course on molecular modelling. Great to see the video, and modelling of some more odd molecules!

[mynameismud]

How is "stability" defined for a molecule if the atoms themselves are incredibly unstable?

[PavlockProducts]

Prof is a living legend!!!! Great explanations as always

[spsn]

1:48 not the sort of video where I expected to see those kind of toys, professor

[christmassnow]

Now it's time to talk about the strangest molecule ever made. "Strange" means it defied conventional calculations and simulations and did not behave according to what we initially expected...

I used to watch this channel all the time in college before I switched majors from chemistry to mechanical engineering. I'm happy to say that even though I've since graduated and am no longer in school I still watch this channel years later

Always keeping us interested and informed in chemistry. Thank you.
