of the "Rare Earth Elements" which can located in Group 3 elements
of the Periodic Table and in the 6th and 7th periods. The Rare
Earth Elements are of the Lanthanide and Actinide series. Most of

Uranium was discovered by Martin Heinrich Klaproth in Germany in
1789. Uranium was the first element that was found to be fissile.
Occurrence of the element Uranium
Properties within each individual group are similar, but
nevertheless vary within a group. Generally chemical activity
decreases as the period increases a non-metal group and increases
as the period increases within a metal group. The first element in
a group is always an active metal, the last is always an inactive
non-metal. Common Uses of Uranium
Nuclear fuels
Nuclear weapons
Gyroscopic compasses
