Group one metals are the Alkali Metals, but Hydrogen is placed in group one because of its electron arrangement. All group one metals have one electron in their valence shell (outer most shell) and hydrogen is no exception. It has one electron in its last shell, and is therefore placed in group one even though it is not an alkali metal.
