FTP, name this set of four  numbers, which enumerate the shell, sublevel, orbital, and spin of an electron.
The second refers to angular momentum; the third relates the magnetic field  resulting from momentum to orientation. While the fourth may hold one of only two  values, the first, or principal, has four possibilities, each of which determines the set  of values the second and third may take. A set of four values may not repeat, and  the fourth of these denotes opposing spin values. FTP, name this set of four  numbers, which enumerate the shell, sublevel, orbital, and spin of an electron.
