Metal Deficiency Defects

These contain less number of positive particles than negative particles. These emerge because of two ways:

(i) Cation Vacancies: now and again, the positive particles might miss from their cross section destinations. The additional negative charge might be adjusted by some adjacent metal particle securing two positive charges rather than one. This sort of deformity is conceivable in metals which indicate variable oxidation states.

The basic cases of mixes having this imperfection are ferrous oxide, ferrous sulfide, nickel oxide and so forth.

(ii) Extra anions possessing interstitial destinations: For the situation, the additional anions might involve interstitial positions. The additional negative charge is adjusted by the additional charges on the neighboring metal particles. Such sort of deformity is not regular on the grounds that the negative particles typically huge and they can't without much of a stretch fit into the interstitial destinations.

there are many solids which are difficult to prepare in the stoichiometric composition and contain less amount of metal as compared to the stoichiometric composition.in crystal of FeO some Fe2+ cations are missing and the loss of positive charge is made up by the presence of required number of Fe3+ ions

In FeO, some Fe2+ are missing and charge is balanced by Fe3+, now Fe ions is reduced not O reduced but here in the statement formula is FeO(0.98), therefore it should be a false statement.

If there is any mistake in above answer then plss correct me
