Below are four sets of quantum numbers ((n,l,ml,ms) for four electrons in a Krypton atom:
i) (3,2,1,+1/2). ii) ( 3,1,1,+1/2) iii) (3,0,0,-1/2) iv) ( 3,1,0,-1/2)
Which two sets would represent electrons in orbitals with the exact same energy?
A) i and ii B) i and iii C) i and iv D) ii and iii E) ii and iv
