Explain your reasoning for your formula prediction for ba+2 and s-2. a neutral molecule requires equal numbers of cations and anions. atoms will not combine unless their ions have an equal but opposite charge. the total charge of cations plus anions must equal zero. all of the above

The total charge of cations plus anions must equal zero.

Explanation:

The result Barium sulfide which is arrived upon because the total charge of cation plus anions =0

+2+(-2)=0 as seen above. The product is an electrically neutral compound.

Ba²⁺+ S²⁻⇒BaS

The product is a solid which is in the looks of black ash.
