(a) Figure out the electron configurations (in the notation of Equation 5.44) for the first two rows of the Periodic Table (up to neon), and check your results against Table 5.1.
(b) Figure out the corresponding total angular momenta, in the notation of Equation 5.45, for the first four elements. List all the possibilities for boron, carbon, and nitrogen.
