Question

Magnetic moment due to the motion of the electron in $n^{th}$ energy state of hydrogen atom is proportional to

• A. n
• B. $n^0$
• C. $n^5$
• D. $n^3$

Answer 1

Answer: (A)

$\frac{MagneticMoment}{AngularMomentum}=\frac{e}{2m}$
$\therefore$ Magnetic Moment $\propto$ angular momentum
M $\propto$ n $\left(L=\frac{nh}{2\pi }\right)$
