Answer:
ok
Explanation:
On doping germanium with gallium, some of the crystal sites are occupied by gallium atoms. Three electrons of gallium are used for making bonds with germanium while the 4th electron of germanium remains unbounded and thus is free for movement and increases the conductivity of crystal.
