2.  Which of the electron configurations above is possible for the ground state of P? 
(e)
3.  Which of the electron configurations above describes an excited state of Mg+?
(c)

4.  Is the following electron configuration consistent with Hund's rule of maximum multiplicity?

Yes, all electrons unpaired before pairing

5.  Is the following electron configuration consistent with Pauli's exclusion principle?

No, two electrons in a p orbital have the same four quantum numbers

6.  What is the orbital energy diagram that best describes the core electron configuration of Si ?

Did you draw the core or did you draw the valence electron configuration by mistake ?
