To create Plutonium (which is also used for nuclear bombs and power plants)
D. 5 facts about the element:
1) 1 kilogram of Uranium 235 (U235) can produce 80 TERAJOULES of electricity (to know how much that is, if you had an electric car powered by 1 kg of U235, it would let you drive at an average speed on an average day for 1000 YEARS!!!)!
2) A typical nuclear power plant has only 1 kg of Uranium, and it’s only 3% enriched (there’s U235 and U238. Uranium 238 is practically worthless. It’s not that radioactive and produces almost no energy. You need to enrich your Uranium to get all the U238 out, and 3% enriched still has a ton of U238 in it)!
3) In order to craft a nuclear bomb, unlike the uranium in a power plant, which manages to create an amazing amount of electricity, you need up to 13 kg of 90% enriched Uranium to craft it, meaning it is SIGNIFICANTLY more powerful than a nuclear power plant, that can still power one whole city, or more!
4) Uranium is so dense, that it sinks in mercury!
5) Depleted uranium (which is uranium that has 0.03% or less U235) is used for bullets and armor. Given that it is so dense and poisonous, it does all that lead does, but better and more effectively. When the depleted Uranium hits a wall, it becomes a dust. If you inhale that dust, you get poisoned, and it could form an acid in your
