1. The problem statement, all variables and given/known data Set up the Schroedinger Wave Equation for Li. Hint: Don’t forget to consider electron-electron interactions. 2. Relevant equations H^[tex]\Psi[/tex]=E[tex]\Psi[/tex], etc. 3. The attempt at a solution I understand how to set up the equation, i.e. how to use the H^ operator, obtain solutions for [tex]\Psi[/tex], and I'm fairly sure I can solve it (for H anyway). I'm more unsure of how to solve it for multiple electron atoms than anything else. I'm guessing that I'll have to do it three times, once for each electron. Is this correct? Also, where do I begin to account for electron-electron interactions? I'm not sure what this means, as we never explicitly went over it in class. Does this pertain to the charges, or just positions? I'm not asking anyone to do the problem for me (I'd much rather do it myself actually), but if someone could give me a place to start, I'd appreciate it; I'm completely lost.
