Which inaccuracy arises when approximating atomic electron wave functions?

💡 Explanation

Approximations in wave functions can inaccurately describe electron momentum; because the kinetic energy operator involves momentum squared, **perturbation theory** leads to its overestimation. Therefore, kinetic energy is too high, rather than electron attraction, at fixed potential, occurs under realistic conditions.
