Ionic compounds can be made from a metallic ion and a nonmetallic ion. Metallic ions (M) are positive (cations). Nonmetallic ions (N) are negative (anions). x stands for the number of metallic ions and y stands for the number of nonmetallic ions. For each equation given below, enter the number in the space provided to correctly answer the question.
x(+1M) + (–2N) = 0
What does x have to be?
(+2M) + y(–1N) = 0
What does y have to be?
x(+2M) + y(–3N) = 0
What do x and y have to be? x =
and y =
