Which outcome arises when an electron's confinement increases?

A)Increased uncertainty in its momentum
B)Reduced probability density amplitude peaks
C)Decreased zero-point energy magnitude
D)Lower probability of quantum tunnelling

💡 Explanation

Increased confinement raises energy eigenvalues of the electron's wave function because the Heisenberg uncertainty principle dictates that position and momentum uncertainties are inversely related. Therefore, momentum uncertainty increases, rather than decreases in zero-point energy, due to confinement potentials.
