Question

Predict the formula for Ba+2 and S-2

Answer 1

- BaS

Reason: We know this because if you take positive 2 (+2) and negative 2 (-2) then you put them into the equation (+2-2)= this equals 0 (zero.) So, we know that this is an ion (charged particle that has neither positive nor negative charge.)

Answer 2

I believe it is BaS I hope this helps!
