Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23 Na. The free metal does not occur in nature and must be prepared from compounds.
Legend. primordial. element by radioactive decay. The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), [note 1] rubidium (Rb), caesium (Cs), [note 2] and francium (Fr). Together with hydrogen they constitute group 1, [note 3] which lies in the s-block of the periodic table.
