The values for quantum numbers (QNs) corresponding to each of the two (2) electrons in the 1s orbital (in the K shell) are: { = 1, = 0, = 0, " = 1/2} and { = 1, = 0, = 0, " = 1/2}. Write the values of the four (4) QNs for all the electrons in the M shell, and note which correspond to the s, p, and d subshells
