Which consequence results when electron shielding decreases in atomic orbitals?

A)Increased effective nuclear energy seen
B)Degeneracy of orbitals greatly increases
C)Atomic radius size correspondingly increases
D)Spin-orbit coupling effects get minimized

💡 Explanation

Decreased electron shielding leads to enhanced effective nuclear charge because the remaining electrons experience a greater attractive force from the nucleus; therefore, the effective nuclear charge rises, rather than atomic radius increasing or spin-orbit coupling minimizing under unaltered conditions.
