1. The problem statement, all variables and given/known data
find each of the angular momentum quantum numbers and the
spectroscopic notation of the ground state electron configuration.

2. Relevant equations
n2s+1L J

3. The attempt at a solution
so for "each of the angular momentum quantum numbers" Im just finding the L in each of the electron config thing? so like for 1S2 would be 0 for the angular momentum quantum? aand for the spectro notation for ground state i would just use the formula and N would be 1?
thanks

The angular momentum quantum numbers are s, l, and j. It sounds like you're being given various atoms and asked to find those quantum numbers when the atom is in its ground state. Once you know those, it's straightforward to write down the same information in spectroscopic notation.
