1.In N-type semiconductor, electrons are majority carriers and holes are minority carriers. In P-type semiconductor, holes are majority carriers and electrons are minority carriers.
2.In ntype substances, majority carriers move from high to low potential.In p type The majority carrier moves from less to high potential.
3.Pentavalent impurities are added in N type. Trivalent impurities are added in P type.
4.Impurity in N type material has the ability to take an electron so it called acceptor atom. In P type materials, impurity provides electrons to so this atom is known as donor atom.

Verified answer
Answer:
In a p type semiconductor impurity from group 3 is added as the impurity known as trivalent impurity such as Aluminum and Gallium.
In a n type semiconductor impurity from group 5 is added as the impurity known as pentavalent impurity such as Arsenic and Bismuth.
