Question

The magnetic moment of electron due to orbital motion is proportional to
($n=$ principal quantum number)

• A. $\frac{1}{n^2}$
• B. $\frac{1}{n}$
• C. $n^2$
• D. $n$

Answer 1

The correct option is D $n$

The magnetic moment of electron can be expressed as

$\mu =\frac{-neh}{4\pi m_e}$ ------ (1)

From the equation we can say that magnetic moment $\mu$ is directly proportional to the principal quantum number.
