Question:

Magnetic moment due to the motion of the electron in nth energy state of hydrogen atom is proportional to:

Options:

$n$

$n^2$

$n^3$

$n^0$

Correct Answer:

$n$

Explanation:

The correct answer is Option (1) → $n$

The Angular momentum (L) is,

$L=nh$ [n = Principle quantum number]

and,

Magnetic moment ∝ L ∝ n

⇒ Magnetic moment ∝ n
