In the ground state, the outermost shell (n = 1) of helium (He) is filled with electrons, as is the outermost shell (n = 2) of neon (Ne). The full outermost shells of these two elements distinguish them as the first two so-called "noble gases." Suppose that the spin quantum number ms had three possible values, rather than two. If that were the case, which elements would be
(a) The first and
(b) The second noble gases?
Assume that the possible values for the other three quantum numbers are unchanged, and that the Pauli exclusion principle still applies.
