Alkali metal - Wikipedia

The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). Together with hydrogen they constitute group 1, which lies in the s-block of the periodic table.All alkali metals have their outermost electron in an s-orbital: this shared electron configuration results in their having very similar characteristic properties.
