Lithium is a chemical element, having the chemical symbol Li. Its atomic number (the number of protons) is 3. It has a standard atomic weight of 6.941, and is typically found as a solid in its elemental form.
Lithium is considered to be a member of the "Alkali metal" class of element. At a pressure of 101.325 kPa, it has a boiling point of 1342 °C, and a melting point of 180.5 °C
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]
