Ionic lattice has two major point defect...

Ionic lattice has two major point defects, (1) Schottky (2) Frenkel defects, Schottky defects occurs due to the cation - anion pairs missing from the lattice sites, Frenkel defects occur when an ion leaves its lattice site and fits into an interstitial space. The neutrality of the crystals is being maintained and we considered all losses from interstitial postions
Structure shown here represents: 

A

Schootky defect

B

Frenkel defect

C

Both defect

D

None of these

Text Solution

Consider following statements I: If three Fe^(2+) are missing from its lattice site in FeO , then there must be two Fe^(3+) ions somewhere in the lattice to balance the electrical charges II : Crystals with metal deficiency defects are called super-conductors III: Crystals with metal deficiency defects are called semiconductors The correct statements are
