Lithium-8 have five neutrons.
Lithium-9 have six neutrons.
Lithium-11 have eight neutrons.
Lithium-4 has one neutron.
Lithium is alkali metal.
It is present in 1st group.
Its atomic number is 3.
Its atomic mass is 7 amu.
Lithium salts are used in psychiatric medicine.
This is a reduction reaction as the oxide(oxygen) is taken away from the metal =]
