The small,but important,energy differences between 3s,3p,and 3d electrons is a consequence of
A) the number of electrons they can hold
B) their principal quantum number
C) the Heisenberg uncertainty principle
D) thier effective nuclear charge
E) Hund's rule

Question

Quizplus · Accepted Answer

The energy differences between 3s, 3p, and 3d electrons are primarily due to their effective nuclear charge. Electrons in different orbitals (s, p, d) experience the nuclear charge differently because of their shapes and distances from the nucleus, affecting their energy levels.
