Question

Azimuthal quantum number defines

• A. e/m ratio of electron
• B. angular momentum of electron
• C. spin of electron
• D. magnetic momentum of electron

Answer 1

Answer: (B)

Azimuthal quantum number defines the spatial distribution of electron cloud and angular mementum.

e.g. $l=0,s-$ sub sehll

$l=1,p-$ sub shell

$l=2,d-$ sub shell

Orbital angular momentum of an electron is calculated using the expression. $=\sqrt{l(l+1)}\frac{h}{2\pi }$
