Hydrogen and Sodium are both part of the alkali group.
Hydrogen has an atomic weight of 1.008 while Sodium has an atomic weight of
22.99. Hydrogen has only one electron while Sodium also has one electron in the
outer shell. So both Hydrogen and Sodium has a charge of +1. Hydrogen is
actually a gas while Sodium is a metal. Sodium is never a diatomic molecule,
whereas Hydrogen is a diatomic molecule. So it can be seen that there are
similarities as well as differences between Hydrogen and Sodium.
