Question

Effective magnetic moment can be calculated by using the formula (n- Number of unpaired electrons)

• A. $\sqrt{n(n+1)}$
• B. $\sqrt{n(n-1)}$
• C. $\sqrt{n(n+2)}$
• D. $\sqrt{n(n-2)}$

Answer 1

Answer: (C)

The explanation correct option:

Option(C) $\sqrt{n(n+2)}$

• The Formula used to calculate effective magnetic moment is$\sqrt{n(n+2)}$ B. M.
• Where, $n$ is the number of unpaired electrons in the orbital of the atom or ion.

• The effective magnetic moment is a convenient measure of a material's magnetic properties because it is independent of temperature as well as external field strength for diamagnetic and paramagnetic materials

Hence, Option(C) $\sqrt{n(n+2)}$ is the formula used to calculate the effective magnetic moment.
