Assertion (A): An n-type semiconductor contains a large number of extra electron

1. Assertion (A): An n-type semiconductor contains a large number of extra electrons, yet remains electrically neutral overall. Reason (R): An n-type semiconductor is created by doping an intrinsic semiconductor with a pentavalent impurity. Which is correct?

 

Both statements are true. But overall neutrality comes specifically from each donor atom becoming a fixed positive ion after releasing its extra electron, balancing the added negative charge — a detail beyond what R alone states.
