An electron in a hydrogen atom undergoes a transition from a higher energy level to a lower energy level. The incorrect statement of the following is .

Options

A. Kinetic energy of the electron increases
B. Velocity of the electron increases
C. Angular momentum of the electron remains constant
D. Wavelength of de - Broglie wave associated with the motion of electron decreases.

Answer

C

Explanation

Angular momentum = mvr
Angular momentum is dependent on radius as electron jumps from one orbit to another orbit its radius changes. Hence Angular momentum does not reamian same.
