← ScienceWhich outcome results when electron shielding decreases in germanium?
A)Core electrons see increased nuclear charge✓
B)Valence electrons experience less attraction
C)Atomic radius significantly expands outward
D)Ionization energy threshold exhibits decrease
💡 Explanation
Decreased shielding causes increased effective nuclear charge; the `electron-electron repulsion effect` is reduced, because electrons orbit closer to nucleus. Therefore core electrons experience greater attraction rather than reduced attraction as weaker shielding results from orbitals modifications.
