Hole is

A

an anit-particle of electron

B

a vacancy created when an electron leaves a covalent bond

C

absence of free electrons

D

an artificially created particle

Text Solution

Verified by Experts

The correct Answer is:
B
The concept of hole describes the lack of an electron at a position where one could exist in an atom or atomic lattice. If an electron is excited into a giher state, it leaves a hole in its old state.
Thus, hole can be defined as a vacancy created when an electron leaves a convalent bond.
