Meaning
Uranium is a Actinide metal element, on the Periodic Table, with an atomic number of 92.
About Uranium
Molecular Structure
- Uranium has the chemical symbol U.
- Uranium atoms join together in large numbers to form a giant metal molecule.
Atomic Structure
- Uranium as 92 protons and 146 neutrons in its nucleus giving it an Atomic Number of 92 and an atomic mass of 238.
- Uranium is in Period 7 of the Periodic Table because it has 7 electron shells.
Properties
