Question

Which of the following are permissable sets of quantum numbers for an electron in a hydrogen atom? The atom may be in an excited state (ie the electron need not be in its ground state). Choose all of the correct possibilities n- 4,1-2, m,- -2, m, -1/2 1./ 2. m = +1, - +1/2 n 5 ,1 = 2 m = 0, m,- +1/2 n= 6,1 5 m +6, m = -1/2 On-3,1-2, m,- +2, m,- +1 On4,-3, m = -3, m,- +1/2 On=3,1 - 1, m = -1, m,- +1/2 On-4,1-2, m = +2, m, --1/2 2.1 1, my0, m,- +1/2 n-4,1-1, m,- +1, m,- +1/2

Answer 1

l so not - greater than possible a - 1) n=4,2=2, me=-2, n.g= -1/2 1 ud Possible 2) mei, b=2 , me = tl , ms=th - ld not possible 3) n=5, 1=2, me =0, ms=41/ 5d possible 4) n=6,d=s, me=t6, ms=-1/2. me can't be greater than e so, not 5) m-3,4-2, me =+2, mis=+1 1 ms can have either th oral value so - not possible. 6) n=4, l=3, me=-3, ms=t/ Чf - | Possib) 7) N=3, b=l, me =-1, ms=+1/2 - 3p Possible 8) M=4,2=-2, mesta, ms --112 l can't be negative, so not possible. q) n=2, l=1, me =0, ms=+1/2 - 2p Possible 10) n=4, l = 1, me=+1, ms=all Scanned with come p- possible
