Calculate the `Z_(eff)` felt by a 2p electron of the nitrogen atom.

Text Solution

Verified by Experts

Electronic configuration of nitrogen atom is `1s^2`
There are 4 other electrons in (2s 2p) group.
Screening constant, `sigma` for 2p electron `4xx0.35+2xx0.85= 3.10.`
Therefore, `Z_(eff)` felt by 2p electron=`Z_(eff)=Z-sigma=7.0-3.10 = 3.90 `
