Hi everyone! I guess you have figured that this video is going to be about such a metal as uranium. However, let me make give a small warning in order to calm you down. I think now we have settled everything and can move on to considering properties of the most dangerous metal on earth - uranium. Uranium belongs to the actinides series in the periodic table that is to radioactive elements and its atomic number is 92. Uranium is 40 times more abundant in earth’s crust than silver. It forms in abundance upon rapid neutron capture inside spinning supernovas. That is why uranium was discovered quite early, in Germany in 18-th century. Its discoverer, Martin Heinrich Klaproth, named it after a newly discovered planet of the solar system, after Uranus. In nature uranium is often found in such minerals as uraninite and autunite. This metal often has several oxidation states in those minerals. Thanks to the beautiful yellow colour of such minerals, glass blowers added them to glass. As a result minerals would give such glass a beautiful greenish colour. It’s a pity that back then craftsmen didn’t not about the toxicity of uranium compounds. Nevertheless, pure metallic uranium can be obtained from uranium ore via reduction by calcium which looks very ordinary. Since mostly uranium naturally occurs in the form of uranium-238 isotope with a half-life of about 4.468 billion years, in 99, 23% of cases to be precise. Depleted uranium is most frequently used for chemical researches, that is uranium-238, in order to reduce scientists’ exposure to its radiation. Also there are only two radioactive metals that occur naturally. Those are uranium and thorium. It’s so because of their extremely long half-lives. Pure uranium obtained from its ore looks quite dark as its surface oxidizes pretty fast because of the high chemical activeness of this metal. That is why it is often stored in argon and also all experiments with uranium are conducted in argon medium. Usually a piece of pure metallic uranium-238 is ripped to such small shreds on a lathe in a laboratory. It is noteworthy that these shreds in the test tube already emit beta and gamma radiation.

"Do not try this at home even if you have 2 pounds of uranium in your garage"

God I love russian humor

[TheSkorpion]

I like how he speaks with a very heavy accent but has perfect grammar...

[Oxazepam]

You have the perfect accent to describe uranium. Just like french accent is perfect at describing wine. You sound like a uranium connoisseur.

"Don't try this at home"

Damn, I was going to buy some uranium at Walmart to make a small atomic bomb for scaring the dogs.

"Maybe he cannot make a video on uranium"
*Thou should never challenge Russians*

[Thoisoi]

Hello everyone! Please help me with making subtitles to this video!

- "And don't try to repeat these experiments at home, even if you have two pounds of uranium in your garage"
Codyslab: **H M M M**

"Do not try at home"
* sad glance to my 15 pound uranium rods *

Uranium: Iam the most dangerous metal on earth
Plutonium: LOL

[vernonvouga]

I just need to point out that I love all of your videos man. Thank you for the intellectual content

[foxys]

The deep Voice of him makes me feel like I'm watching a Discovery channel

Not great, not terrible...

[monabil]

My ex-girlfriend is more toxic than uranium

[junaidsiddiquemusic]

1:24 unfortunately I have 2 jars full of Uranium in my washroom.

[danielbrown]

Watched Chernobyl and can’t stop learning. Interesting stuff

[jasondragon]

This dude is the most dangerous man on earth he knows all the elements and has access to them all and is the only man who knows their true power

[Auriam]

Great video, thank you for actually visiting a chemical research lab and not just showing some rocks containing uranium and some stock photos and footage like most channels. I love that you actually went out and did some research and on-location shooting and interviews. That's what makes this video so much better than most. And it shows that you're well on your way to being a major YouTube creator.
