`{:("Given",K,L,M,N,),(,2,8,11,2,):}`
The number of electrons present in `l=2` is -

A

`3`

B

`6`

C

`5`

D

`4`

Text Solution

Verified by Experts

The correct Answer is:
A
`K = 2e^(-) = 1s^(2)`
`L = 8e^(-) = 2s^(2) 2p^(4)`
`M=11e^(-)=3s^(2)3p^(6)3d^(3)`
`N = 2e^(-) = 4s^(2)`
for `d e^(-)=3, l=2`
