← ScienceWhich consequence occurs when the He atom 1s orbital overlaps?
A)Electron density increases between nuclei✓
B)Nuclear shielding effect remains unchanged
C)Total kinetic energy stays constant
D)Potential energy function remains identical
💡 Explanation
Increased electron density happens because constructive interference, a form of linear combination of atomic orbitals (LCAO), generates a bonding molecular orbital. Therefore, a more stable lower energy configuration forms, rather than other, typically, higher-energy antibonding orbitals.
