MCQ
Effective magnetic moment of $S{c^{ + 3}}$ ion is
- A$1.73$
- ✓$0$
- C$5.92$
- D$2.83$
✓
Answer
Correct option: B.
$0$
b
(b) $B.M.\,=$ $\sqrt {n(n + 2)} $ Where $n = $ number of unpaired electron
(b) $B.M.\,=$ $\sqrt {n(n + 2)} $ Where $n = $ number of unpaired electron
For $S{c^{3 + }} = 3{d^0},\,n = 0$, $\therefore \,\,\,\mu = 0$
