← ScienceWhich outcome arises when repulsion modifies atomic orbitals?
A)Energy level splitting (Stark effect)✓
B)Increased nuclear binding energy
C)Decreased ionization potential
D)Wider conductivity bandgap
💡 Explanation
Energy level splitting, due to electron shielding, causes differential energy changes. This is electrostatic repulsion. Because certain orbitals become more stable than others, we see distinct energy level splitting rather than simple ionization because shielding and interactions matter.
