Question : 58

Total: 90

Which of the following is false?

When NaCI is heated in the atmosphere of Na, metal excess defect arise due to the migration of Na from vapour to NaCI lattice.
Both Schottky and Frenkel defects can effect electrical conductivity and this conduction is known as intrinsic semiconduction
Density decreases in Frenkel defect but remains same in Schottky defect
In compounds having metal excess defect F-centres are present which makes them paramagnetic, coloured and help in n-type semi conduction
