F centre is an example of metal excess defect due to the presence of extra cations at interstitial sites. Zinc oxide is white in colour at room temperature, on heating it loses oxygen and turns yellow. ZnO overset("Heat")toZn^(2+)+(1)/(2)O_(2)+2e^(-) Now there is excess of zinc in the crystal and its formula becomes Zn_(1+x) O. the excess of Zn^(2+) ions move to interstitial sites and the electrons to neighbouring interstitial sites. There are many solids which are difficult to prepare in the stiochiometric composition and contain less amount of the metal as compared to stiochiometric proportion. a typical example of this type is FeO which is mostly found with a composition of Fe_(0.95) . it may actually range from Fe_(0.96) O. Q. In Fe_(0.95) O:
