1. Write the term symnbols for carbon atom He2s^{2}2p^{2}which has two equivalent p electrons taking into account the Pauli exclusion principle.

2....

3. Since the carbon has two equivalent p-electrons, we know the l_{1}=1 and that l_{2}=1 as well. Also the spins for both the electrons are 1/2. So the sum of the spin is either 1 or 0. I'm not quit sure where to go from here. l = 2, 1 or 0, meaning we have S, P and D terms. I tabulated a table of 15 elements permuting the various l, s terms for the two electrons making no two have the same numbers. Is there an easier way to do this?

So, Far I've gotten^{1}D_{2},^{3}P_{2,1,0},^{1}P_{1}and^{3}S_{1}. Are there all the terms?
