Question 1
1 / -0

The following question has four choices out of which ONLY ONE is correct.

The magnetic moment (µ) of a revolving electron around the nucleus varies with principal quantum number n as

A
μ ∝ n

B
μ ∝ 1/n

C
μ ∝ n²

D
μ ∝ 1/n²

Solution

Velocity of the electron orbiting around the nucleus

v ∝ 1/n ----- 1

and

Radius of the orbit
r ∝ n² ------ 2

Magnetic moment (μ)= (mvr)/2 (m is mass of the electron which is constant) ........... (3)
Therefore,

From 1 m, 2 and 3 we have

μ ∝ n
