Answer:

#BaO#

Explanation:

Barium cation has #+2# charge and oxide anion has #-2# charge .

Answer:

#BaO#

Explanation:

Barium oxide is an ionic compound, compromised of a barium metal cation, and an oxygen non-metal anion. Looking at the periodic table, oxygen is in group #6# or #16#, and will therefore have an oxidation number of #-2#, while barium sits in group #2#, and will have an oxidation number of #+2#.

So, one ion of barium neutralizes one ion of oxygen, and so those two combine to form barium oxide, #BaO#.
