Question

Choose the incorrect statement

• A. The shape of an atomic orbital depends upon the azimuthal quantum number
• B. The orientation of an atomic orbital depends upon the magnetic quantum number
• C. The energy of an electron in an atomic orbital of multi-electron atom depends only on principal quantum number
• D. The number of degenerate atomic orbitals of one type depends on the value of azimuthal and magnetic quantum numbers

Answer 1

Answer: (C)

In atoms with multiple electrons the energy of an electron depends not only on the intrinsic properties of its orbitals, but also on its interactions with the other electrons. These interactions depend on the detail of its spatial probability distribution, and so the energy of orbitals depends not only on n but also on l
