The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium KR), rubidium (.b), caesium (Cs), and francium (Fr).Together with hydrogen they constitute group 1, which lies in the s-block of the periodic table. Most alkali metals have many different applications, such as rubidium and caesium atomic clocks, sodium-vapor lamps, and table salt.
