Chemistry - Atomic Structure Question with Solution | TestHub

Hydrogen energies depend only on n, so A is false. B is the intended outermost radial-maximum order. The diagrams in C have 2,4,2 unpaired electrons and spin multiplicities 3,5,3, so C is false. Under D's artificial rules n=2 permits l=0,1,2 and m=-2l through +2l gives 1,5,9 values. Four distinct spin values would give 4(1+5+9)=60, as intended by the key. However the source prints -3/2 twice and omits +3/2. Taken literally there are only three distinct spin values and 45 allowed states. Printed A,C is retained; D requires the likely last-spin-sign repair before the stated 60 is justified.
