Which energy level shift results when two hydrogen atoms approach?

A)Antibonding orbitals increase significantly
B)Bonding orbitals increase dramatically
C)Atomic orbitals remain degenerate
D)Kinetic energy dominates the shift

💡 Explanation

Antibonding orbitals gain energy through destructive interference by electron waves, forming a higher energy state; therefore antibonding becomes increased rather than bonding stabilization, because potential energy decreases with bonding.
