Is a p-type semiconductor charged or electrically neutral?

Why n-type and p-type semiconductors are electrically neutral?

Distinguish between an intrinsic semiconductor and p-type semiconductor. Give reason, why a p-type semiconductor crystal is electrically neutral, although n_h>>n_e ?

A n-type semiconductor is:

How does a sample of an n-type semiconductor electrically neutral though it has an excess negative charge carriers?

What is n-type semiconductor ?

Why can't we take one slab of p-type semiconductor and physically join it to another slab of n-type semiconductor to get a p-njunction?
