Allowed values for the quantum numbers of electrons are as follows:

The relationships between n and the shell designations are noted in Table 2.1. Relative to the subshells,

                                                   l = 0 corresponds to an s subshell

                                                    l = 1 corresponds to a p subshell

                                                    l = 2 corresponds to a d subshell

                                                   l = 3 corresponds to an f subshell

For the K shell, the four quantum numbers for each of the two electrons in the 1s state, in the order of nlm_lm_s, are 100() and 100(). Write the four quantum numbers for all of the electrons in the L and M shells, and note which correspond to the s, p, and d subshells.

n = 1, 2, 3, ... 1= 0, 1, 2, 3, ... , n-1 m = 0, =1, 2, +3, ..., 1 +I
