Chemistry Question on Some Applications of d- and f-Block Elements

The total spin resulting from a d7d^{7} configuration is

A

±1/2\pm 1/2

B

±2\pm 2

C

±1\pm 1

D

±3/2\pm 3/2

Answer

±3/2\pm 3/2

Explanation

Solution

d7d^{7} configuration has three unpaired electrons. Thus, total spin = ?1/2 ? no. of unpaired electrons =±12×3=±32=\pm \frac{1}{2} \times3=\pm\frac{3}{2}
