Do not repeat the experiments shown in this video!
Animation of atomic bombs:
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.

Hello everyone! Please help me with making subtitles to this video!
I Zink thatt the name of the metal is Ukranium…
how to make atom bomb at home? please make a video about this
𝐎𝐡𝐡 𝐓𝐡𝐚𝐭𝐬 𝐧𝐢𝐢𝐜𝐞𝐞𝐞𝐞.
0:50
this is filmed like a porno
most dangerous element on earth is Polonoium, please study
I like graphite and uranium but I prefer uranium.My dad work in a lab, sometimes I visit him and learn more about graphite that uranium
As if we get Uranium in our backyard ,,,,to try this at home… 🤣🤣🤣🤣👍
2000 people dies in Hiroshima, hope this was the only piece of information you were wrong about
2:11 My anus?
How am I supposed to repeat this experiment
0:30 lol
What about plutonuim or organic mercury compound dimethylmercury
Glad to get explained by Russian speaker.
20k not 2k murdered in Hiroshima
😮👏👏👏👏👏👏
So, Does nuclear powered vessel like Submarine uses this ?
Teacher : "ok tomorow we gonna learn about Uranium"
Girl be like : "That's dangerous, coz it'sa radioactive, it's a toxic, it could exploades"
Boy be like : "Awesome…. damn where did i put my GP-5 masker ?"
What? Just 2000 people killed in Hiroshima? Are you kidding?
FBI probably watching
Horang INDONESIA mana cuk masak gak pengen mngenal plajaran ini
the gloves are like don't leave me hanging bro. bro bro don't leave bro.
와 이분 모하는분이지? 리얼 우라늄238을 가지고 노네..
우뢰늄 많이 만져서 인지,손 이 좀 상하고,살짝 기형 됐내ㅎㅎ
titanium
pls
Thank for upload about uranium
That girl
When mario brothers talks with their mouth full with mushroom
Urineium
Don´t repeat this experiment at home… Oh well … But then what do I do with the 50kg bag of U235 that I have in the garage …? …😄
no dibulguen selcium 121 venezuela auxilio coltan ….uranio auxilio
jajajajaja selcium 121 ese si es bad
Indonesia nyimak
Thanks for subtitle indonesia . Nice vidio!
Vibranium
Wow . . .
Vídeo com legenda em português! Muito obrigado aos que o fizeram! Excelente vídeo!
I hate your fucking voice!!!
Newly discovered planet " Your anus "
