Litium has a structure
[tex]1s^22s^1[/tex]
What is the first exited state of litium?
I have some doubt? I think that it is
[tex]1s^22p^1[/tex]
Is it correct or maybe
[tex]1s^23p^1[/tex]
Why I'm in problem. Because wave function of hydrogen atom depends of three quantum numbers
[tex]\psi_{n,l,m}[/tex] but energy depends only of one quantum number [tex]E_n[/tex]. So we have degeneration. In this logic it's need to be [tex]1s^23p^1[/tex]. But I don't have hydrogen I have litium, so must be some ecranisation and of course Hund rule [tex]s[/tex] and [tex]p[/tex] orbitals have different energy. And I can say that
[tex]E_{n,l}=-13,6eV\frac{1}{(n-\Delta l)^2}[/tex]
Thanks for your answer!
