In which orbital would an electron feel the highest effective nuclear charge?

Question

Quizplus · Accepted Answer

The effective nuclear charge (Z_eff) is the net positive charge experienced by an electron in a multi-electron atom. The closer an electron is to the nucleus, the higher the effective nuclear charge it experiences. The 3s orbital is closer to the nucleus compared to the 4s, 3p, 4p, and 3d orbitals, meaning electrons in the 3s orbital would feel the highest effective nuclear charge.
