Question

The magnetic moment of electrons due to orbital motion is proportional to ______.

(n = principal quantum numbers)

Options

• `1/"n"^2`

• `1/"n"`

• n²

• n

Answer 1

The magnetic moment of electrons due to orbital motion is proportional to n.

(n = principal quantum numbers)

Explanation:

The magnetic moment of the revolving electron is given by, M = `("neh")/(4pi"m") = "n"("eh"/(4pi"m"))`

 Thus, M ∝ n (the principal quantum number).
