A kilogram of ANY element - Periodic Table of Videos

Nowadays Pirocton-Olamin is used instead of selenium sulfide in Head and Shoulders shampoo.

About 1KG of any element, it would be Iridium in a form of necklace. I would never abandon it for any* money.
*except ridiculous amount like 1000000000 USD.

I would love to have a kilogram of Unobtainium. 😂

I would want two elements for comparison ... 1 kg of hydrogen alongside 1 kg of osmium. The lightest next to the densest element.

Now, since 1 mole of any gas at STP occupies 22.4 cubic decimetres, and 1 mole of hydrogen is just 2 grams, 1 kg would be 500 moles, and would occupy 11,200 cubic decimetres, or 11.2 cubic metres.

Meanwhile, the 1 kg of osmium would occupy a volume of just over 44 cubic centimetres.

The visual comparison would be interesting to put it mildly.

I'd like to know if the professor has, or has ever had his own chemistry set at home. Does he have any entertaining stories from using it?
I always wanted a kilogram sphere of osmium until I learned of toxicity concerns. It would be a novelty to hold.

Give me a kg of platinum please

Wedding pic of Mrs. Prof - what a stunner! ❤

What a guy

I need a kilogram of Francium for....reasons. 😅

The standard Head and Shoulders in the USA has never contained selenium, it uses a zinc compound. Selsun Blue uses selenium. (H&S seems to have a new item with Selenium that is very clearly marketed as a Selsun Blue competitor right down to adding menthol and the color of the bottle.)
As an aside, the selenium compound gives hair a slight odor of burning plastic.

Bismuth crystal

The Prof is punching!

I would choose a kg of Osmium, just to admire how small a kg of something can get.

Oganesson, just to see what would happen.

Proud Tungsten Cube Owner here, no regrets!

A kilo of Wtf the element of surprise.

Tantalum-180m.
If you know why, then kudos to you! 🙂

asking him all these personal questions: yet their is a leviathan in the room: when did he get the shakes? Used to watch his vids from before covid: no shakes there and seemed to have more presence of mind.
I'd guess the prof took the experimental covid vax and 3 of its experimental boosters and got more than he expected which resulted in less.

About Selenium - reminds me of a comedy SciFi movie called "Evolution". They use a lot of shampoo bottles to exterminate aliens.

How can you not want a kilo of Francium

You will get to physically see it, have bragging rights that you own 4000% of the world supply.

More than 55 years, congrats

Osmium.
Density is very cool & also waaaaay under appreciated.

A kilo of Cesium would be a lot of fun to play with.

The most wholesome video I've seen in a long time.

When you can carry off hair like the Proff you just know you’ve completed chemistry!

I love this! Thanks for sharing. :)

Some real soft-ball questions! I'm sure there's some juicier, more science-y questions rattling around that could be asked!

Why are you abusing the elderly? Let this man sleep

Very misleading title. First and last time I have been on this channel. Don't insult your audiance.

1kg of mercury, which looks kinda cool. The metal from the T1000! 😂 But 1kg is just 75ml! 1kg o Osmium would be even stranger, a 1kg coin/disc with just 44ml, this is disc of 43mm diameter and 3mm thick!

I would own a kilogram of steel and a kilogram of feathers just so I could weigh them to compare which is heavier

Professor Sir Martyn is one of my favorite people

1kg of Platinum, due to both how rare, and how practical it is as a catalyst.

I already have a kilo of iron, so many copper or aluminium?

Thanks for this

Whenever I see this man
I can see the love for his work
I hope I gain even 1℅ of his dedication.
Hatsoff 🙏🙏

Tantalum 180m
The only observationally stable metastable isotope state.

I’d prefere 1kg vacuum!

Iridium

thanks!

This guy is showing rapidly aging... I've been watching channel forever, but well i quess its not so long now 😟

Gallium - Because it would be lots of fun, melting it at its relatively low temperature. Would be great to mould shapes, and have people accidentally melt the object and not understand why lol Non-toxic compound variations of course... If not that, then certainly Neodymium, which I could mix to make some powerful compound magnets, lots of fun there.

Plutonium-238. Aside from being worth 50 times its weight in gold, it could heat my house in winter.

Do you wear hats?

What an absolute gem of a video

How much does a kilo of electrons weigh?

I used to love the film Evolution (2001) and Head and Shoulders containing Selenium was a plot point, so I always remembered it even though it no longer contains Selenium

Also, I probably still love it but haven't seen it in a while, I've never seen anyone ever talk about it but I've seen it a dozen times

A kilo of any element? Can I pick the isotope/allotrope? Helium3.

A kg of radon is what I’d have, that way I could quickly drive the bottle over to the nearest neon sign shop and have them fill up a tube with it so I could see the color of the discharge since no photos of it seem to exist
