Which one of the following statements about orbital energies is incorrect? (A)  In the hydrogen atom, the energy of an orbital depends only on the value of  the quantum number  n . (A) In many-electron atoms the energy of an orbital depends on both  n  and  l . (B) Inner electrons shield outer electrons more effectively than do electrons in the  same orbital. (C)The splitting of sublevels in many-electron atoms is explained in terms of the
