Answer» Correct Answer - 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. |
