The barium is in the second group of the periodic table. The elements of this group have two valence shell electrons. These elements have a tendency to produce cations, since it is easier to lose two electrons than gain six. Now, out of options, the chlorine forms an anion. Is an element of group 7, which means that it has a valence of -1. Therefore, in order to bond with Barium, two atoms of Chlorine will be necessary. The second option is the correct one.
