← ScienceWhich outcome results when increased electron shielding occurs in multi-electron atoms?
A)Decreased effective nuclear charge✓
B)Increased ionization energy value
C)Orbital energy level decreases
D)Electron-electron attraction increases
💡 Explanation
Increased electron shielding reduces the effective nuclear charge experienced by outer electrons because the inner electrons' repulsive forces counteract the attractive force of the nucleus, therefore decreasing the attraction rather than increasing it or affecting other properties like ionization energy.
