Alkali Metal (Periodic Table)

Alkali Metal

The alkali metals (also known as the lithium family) in the periodic table include the six chemical elements: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). On reacting with water, these elements form alkalies, so they are known as alkali metals. All alkali metals have one valence electron. These elements are in group 1 of the periodic table, below the hydrogen.
