2. Sublevels of energy levels overlap. A 4s subshell has lower energy than a 3d subshell. The effect of the overlap is that the atom is more stable when the 4s sublevel is of lower energy than the 3d sublevel. When drawing orbital diagrams (placing electrons in orbitals of increasing energy), electrons occupy sublevels of the lowest energy
3. 7. Electrons that occupy an atom's outermost (highest) principal energy level are known as: A. core electrons. C. ground state electrons. B. excited state electrons. D. valence electrons. 8.
