Write outer electronic configuration of ...

Write outer electronic configuration of lanthanoids.

A

`(n-2)f^(1-14)(n-1)s^(2)p^(6)d^(0-1)ns^(2)`

B

`(n-2)f^(10-14)(n-1)d^(0-1)ns^(2)`

C

`(n-2)f^(0-14)(n-1)d^(10)ns^(2)`

D

`(n-2)d^(0-1)(n-1)f^(1-14)ns^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
In lanthanides at no. of copper, `K[Ag(CN)_(2)]` is used instead of `AgNO_(3)`.The reason is less availability of `Ag^(+)` ions, as Cu cannot displace of Ag from `[Ag(CN)_(2)]^(-)` ions.
