Explanation:
FeO has metal deficiency defect. Metal deficiency defect is supposed to arise when there are lesser number of positive ions than negative ions. In case of FeO, the positive ions are missing from their lattice sites.
The additional negative charge is balanced by some nearby metal ion by acquiring one more positive charge. It happens in FeO because Fe has capacity of showing variable oxidation states.
