Lithium is a chemical element, typically found as a solid in its elemental form. It has the chemical symbol Li, atomic number (number of protons) Z = 3, and a standard atomic weight of 6.941 g/mol.

Lithium is considered to be a member of the "Alkali metal" class of elements. At a pressure of 101.325 kPa, it has a boiling point of 1342 °C, and a melting point of 180.5 °C. With a density of 0.534 g/cc, it is lighter than water.

Substance withdrawal syndrome

Substance withdrawal syndrome may occur after discontinuing lithium.[1][2]

Nuclear engineering

6Li, usually as lithium hydride, is the starting material to generate tritium in the Secondary of operational thermonuclear weapons.[3]
