Vedclass · Answer

(C) The effective nuclear charge $(Z_{eff})$ experienced by an electron depends on its distance from the nucleus and the shielding effect of inner electrons.The $4p$ orbital has the highest principal quantum number $(n=4)$ compared to $2p$ $(n=2)$ and $3p$ $(n=3)$.Electrons in the $4p$ orbital are farthest from the nucleus and are shielded by all the inner electrons $(1s, 2s, 2p, 3s, 3p, 3d, 4s)$.Due to the greater distance and increased shielding,the $4p$ electrons experience the lowest effective nuclear charge among the given options.

The bromine atom possesses $35$ electrons. It contains $6$ electrons in $2p$ orbital,$6$ electrons in $3p$ orbital and $5$ electrons in $4p$ orbital. Which of these electrons experiences the lowest effective nuclear charge?
