| The alkali metals are a group in the periodic table. In the modern IUPAC nomenclature, the alkali metals are called the Group 1 elements. The alkali metals contain lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium or cesium (Cs) and francium (Fr).[1] (Hydrogen (H), although nominally also a member of Group 1[2], very rarely exhibits behaviour comparable to the alkali metals.) This group lies in the s-block of the periodic table. The alkali metals provide one of the best examples of group trends in properties in the periodic table, with well characterized homologous behaviour down the group.
