4. Uranium Rare Earth Elements

5. Properties Uranium reacts with most non matalic elements Uranium can form solid solutions with other metals Disolves in some acids but not alkalines Radioactive

6. Other Uses Main ingredient in an Atomic Bomb Nuclear Medicine Smoke Detectors Food Irradiation Armor Piercing

7. Conclusion Uranium is Radioactive which makes it have a big blast. It also react well with the other ingredients in a nuclear weapon so no problems will occure. Other elements in a nuclear weapon is Plutonium for an explotion, Neptuniun and Americium to make a chain reaction, Hydrogen and Helium to combined and make huge amounts of energy.
