`Pd` has exceptional valence shell electronic configuration of `4d^(10)5s^(0)`. It is a member of-

A

`5^(th)` Period, Group 10

B

`4^(th)` Period, Group 12

C

`6^(th)` Period, Group 10

D

`5^(th)` Period, Group 14

Text Solution

Verified by Experts

The correct Answer is:
A
`4d^(10)5s^(0)` is the exceptional configuration of P.d. its electronic configuration should be `[Kr]^(36) 4d^(8),5s^(2)` Thu it
Period `= 5 th`
Group `= ns + (n-1) d` electrons
`= 2 +8 = 10`
