Question

Pd has exceptional outer electronic configuration as $4d^{10}5s^0$, it belongs to

• A. $4^{th}$ period, group 11
• B. $5^{th}$ period, group 10
• C. $6^{th}$ period, group 9
• D. $3^{rd}$ period, group 16

Answer 1

The correct option is B

$5^{th}$ period, group 10

The exceptional outer electronic configuration of Pd Suggests that, its configuration should be $4d^{8}5s^2$,so it lies in $5^{th}$ period and group 10.
