Uranium belongs to the group Actinides. This group is one of the families that are called rare earth metals. All of the elements in this group need special handling due to being either unstable or radioactive.
Uranium has a silvery white appearance to it, and it is normally found in porous rocks like sandstone. The element is found virtually everywhere on Earth, including in ocean water. The high amount of this material provides a useful source of energy and fuel for various applications around the world. Uranium has many uses, from powering nuclear reactors and submarines, to creating other trans-uranium materials.
