1. The problem statement, all variables and given/known data
Structure of natrium
##1s^2 2s^2 2p^6 3s^1 ##
How to calculate ##L## and ##S##?
2. Relevant equations
3. The attempt at a solution
From that ##S=\frac{1}{2}##. I know that I need to get ##L=0## and ##J=\frac{1}{2}##, but I'm not sure why?
