Answer:

Barium typically displays a #+II# oxidation state in its compounds.

Explanation:

Barium salts, #BaX_2#, clearly have an oxidation state of #+II#. Neutral barium metal, of course has a #0# oxidation state, as it has neither donated nor accepted electrons.

That barium takes a #+II# oxidation state, is entirely consistent with its position in Group 2 of the Periodic Table, i.e. 2 valence electrons, which the metal LOSES when it forms an ionic compound.
