I solved a lot of it already, but these 6 problems here are very frustrating and making me confused!


__d__   2.   What type of orbital is designated n = 4, l = 3, m_l = -3?
a.   4s
b.   4p
c.   4d
d.   4f
e.   none



__e__   11.   Hund's rule states that the most stable arrangement of electrons (for a ground state electron configuration)
a.   has a filled valence shell of electrons.
b.   has two electrons per orbital, each with identical spins.
c.   has m_l values greater than or equal to zero.
d.   has the maximum number of unpaired electrons, all with the same spin.
e.   has two electrons per orbital, each with opposing spins.



__c__   12.   What is a possible set of quantum numbers for the unpaired electron in the orbital box diagram below? (^ = arrow pointing up, v = arrow pointing down)
