A. Mg in solid sate show electronig conductivity due to presence of free electrons hence they are known as electronic conductors.
B. MgCl2 in molten state show electrolytic conductivity due to presence of electrolytes in molten state.
C.Silicon doped with phosphorus contain one extra electron due to which it shows conductivity under the influence of electric field known as p-type semiconductor.
D. Germanium doped with boron contain one hole due to which it shows conductivity under the influence of electric field and known as n-type semiconductor.
