Below is a list of the elements from the periodic table that are in the alkali metals group. The alkali metals are a series of chemical elements forming Group 1 of the periodic table. The alkali metals are all highly reactive and are never found in elemental forms in nature. Because of this, they are usually stored in mineral oil or kerosene. They also tarnish easily and have low melting points and densities. Alkali metals form a very wide range of amalgams. They tend to form ionically bonded salts with most electronegative elements on the periodic table, like cesium fluoride and sodium chloride.

Hydrogen: although nominally also a member of Group 1, rarely exhibits behavior comparable to the alkali metals.
