Assertion (A) : The spin only magnetic moment of

{Sc}^{3+}

1.73 {BM}

.

Reason (R) : The spin only magnetic moment (in

B M)

of an ion is equal to

\sqrt{n(n+2)}

, where

n

is the number of unpaired electrons present in the ion.

The correct answer is:

View answer and explanation

Correct option: D

(A) is not true but (R) is true

Option D is correct because Assertion (A) is false, as the spin-only magnetic moment of Sc3+ is 0 BM, and Reason (R) is true, as it correctly states the formula for calculating spin-only magnetic moment.
