9 lis 2017 · 1. IT'S THE HEAVIEST NATURALLY OCCURRING ELEMENT IN THE UNIVERSE. With a nucleus packed with 92 protons, uranium is the heaviest of the elements. That weight once compelled shipbuilders to use...
- Uranium is a heavy, silvery-white metal that is part of the actinide series in the periodic table. - It plays a crucial role in the field of nuclear energy, being a primary fuel used in nuclear reactors. - As a metal, it is solid at room temperature, with a high density and poor electrical conductivity compared to other metals.
In the gaseous diffusion process, uranium hexafluoride gas is pumped into metal tubes made of a highly porous metal. About half of the gas flows, or effuses, through the walls of the tubes. The effused gas and the remaining gas are pumped into separate tubes identical to the first, and the process is repeated.
