Answer:

The formula for iron(II) oxide is #"FeO"#.

Explanation:

The formula for the iron(II) ion is #"Fe"^(2+)"# and the formula for the oxide ion is #"O"^(2-)"#. An ionic compound is neutral, so the positive and negative charges are equal. In the case of iron(II) oxide, one #"Fe"^(2+)"# ion combined with one #"O"^(2-)"# ion creates a neutral compound. #2^+ + 2^(-) = 0#
