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 spa
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=0
and y =
