Which statement best describes how to predict the formula of a stable ionic compound?

a Use the same number of cations as anions so that the compound is neutral.

b Use more cations than anions so that the compound is positively charged.

c Use enough cations and anions so that the total charge is zero.

d Use fewer cations than anions so that the compound is negatively charged

The answer is C.

For example NaCl is an ionic compound. We know that the formula is just NaCl as Na has a + 1 charge and Cl has a - 1 charge. The + 1 and - 1 cancel each other out giving the compound a neutral charge.
