Question

Orbital angular momentum of
p-subshell is :-​

Answer 1

Explanation:

For p orbital l=1 so orbital angular momentum is \/2 h/2pi. h/2pi comes from the wave nature consideration of electron. Waves associated with electrons so circumference of a circle must be integral multiple of wavelength.

Answer 2

The physical quantity known as angular momentum plays a dominant role in the understanding of the electronic structure of atoms. To gain a physical picture and feeling for the angular momentum it is necessary to consider a model system from the classical point of view. The simplest classical model of the hydrogen atom is one in which the electron moves in a circular orbit with a constant speed or angular velocity (Figure 6.6.1). Just as the ordinary momentum m

plays a dominant role in the analysis of linear motion, so angular momentum plays the central role in the analysis of a system with circular motion as found in the model of the hydrogen atom.
