metal excess defect are basicalyy divided into two types:

1. Anion vacancy: A negative ion may be missing from its original positionleaving hole whichi is occupied by electron called f centers.

2 Presence of extra cation in interstitial site: In this case electrical neutrality is is maintained by an electron present at another interstitila site.
