Which outcome occurs when a scanning tunneling microscope's tip approaches molecular orbitals?

💡 Explanation

Quantum tunneling permits electrons to traverse the distance, because the electron's wave function extends into the gap and therefore allows a measurable current to flow, rather than the tip simply charging or Van de Waals forces dominating under those separation constraints.
