About Uranium

Uranium is a highly radioactive silvery metal discovered in the 18th century and named after the planet Uranus. It is very toxic and is dangerous to all living organisms on this planet. Uranium can be extracted from a number of natural ores like carnonites, brannerites, and others. This element is a key one that made it possible to obtain nuclear energy and provide the humanity with it. Uranium-235 is used to initiate nuclear chain reactions and create huge amounts of heat which is used as a source of energy for people and their needs. On the other hand, it is used for developing nuclear weapons, nuclear submarines, and other things.
