Suppose the spin quantum number had four allowed values ms

Suppose the spin quantum number had four allowed values (ms = +1/2, -1/2, +1, -1). Give the atomic numbers of the first three noble gas atoms in this case. Questions to consider: (a) What aspect of electron configurations would change with this change in ms values? (b) Do you expect the atomic numbers of the noble gases to be the same with these altered ms values? (c) What is the property of a noble gas electron configuration, and how do you obtain atomic number from a configuration?
