Solution:

• Uranium is a very important element because it provides us with nuclear fuel used to generate electricity in nuclear power stations.

• Uranium is naturally radioactive: Its nucleus is unstable, so the element is in a constant state of decay, seeking a more stable arrangement.

• Uranium was the element that made the discovery of radioactivity possible.

• U-235 concentrations can be used as fuel for nuclear power plants and the nuclear reactors that run naval ships and submarines. It also can be used in nuclear weapons.

• Atomic number of Uranium is 92.
