Deriving the Spectrum, Ch Many-electron terms, levels and Hund's rules
Problem
Phosphorus's ground configuration is 3p3, three equivalent electrons in a half-filled p subshell.
((a)) State the terms of 3p3 (the same counting method used for two p electrons applies, extended to three).
((b)) Apply Hund's rules to find the ground level.
