are there more options?

sharpsage · Answer

I pretty sure it's not any of those

sharpsage · Answer

I think BaCl2 would be the correct formula.

sweetburger · Answer

was my same idea none of those salts seem possible with the combination of barium and chloride

anonymous · Answer

Barium chloride is the inorganic compound with the formula BaCl₂. It is one of the most common water-soluble salts of barium.

welshfella · Answer

Barium is in Group 2 of the Periodic Table and has 2 valence electrons in its outermost shell, available for bonding. Chlorine has 7 valence elecrons so readily accepts another 1 electron to form a stable octet.  So ionic bonds are formed between 1 atom of barium and 2 of chlorine.
Thus the formula for barium chloride is BaCl2
