# Find the possible states

## Homework Statement

a) Enumerate the possible L and S for the $2s2p3p$ configuration.

b) Find the possible L and S for the $2p^23p$ configuration.

## Homework Equations

$$^{2S+1}L_J$$

$$S=0 (Singlet)$$

$$S=1 (Triplet)$$

## The Attempt at a Solution

First of all, doesn't "enumerate" and "find the possible states" mean the same thing? In my previous courses, we've been asked to find all the possible states for a particular atom, like Boron (for ex., Griffiths Problem 5.12 b) which is simple enough, all I do is write down a table and start listing off the possible total angular momenta.

But for part a), we are asked to enumerate $2s2p3p$. To me this seems like there are three different electrons: the first has n=2,l=0 and the second n=2,l=1, and the third n=3,l=1. How would I go about doing this? I'm just confused that all. Can someone give me a push in the right direction?

Thanks yall
