Is hydrogen placed above the alkali metals because it is a metal?

1 Answer

Hydrogen isn't a metal.

Explanation:

It is located in the alkali metals column of the periodic table but it is a gas in its elemental state; it is only there because of its singular electron and its atomic number of #1#.

Hydrogen typically wants a #+1# charge, but occasionally, if a cation is a strong Lewis Acid, hydrogen can interact with it, having a #-1# charge instead and possessing a lone pair of electrons. EX: #NaH#

The position is not necessarily fixed in periodic table, but it is placed in group 1 mainly due to its primary ionic charge of #+1#.
