Answer:
Ionic compound
Explanation:
Barium Chloride is an ionic compound of barium and chlorine.
Barium is a metal with two valence electrons while chlorine is a non metal with seven valence electrons.
Barium will require two atoms of chlorine to form Barium chloride.
The reaction can be demonsated in the equation below.
Ba2+ + Cl- -----------> BaCl2
In this type of bond, Barium uses its 2 valence electrons to form an ionic bond with 7 valence electrons of chlorine. Chlorine will require its own two atoms to form this type of bond with Barium.
Cl -Ba-Cl = BaCl2
