You are correct that both ii and iii are incorrect and for the reason you cite.
i is correct.
If n = 4, l can be 0,1,2,or 3; ml can be -3.-2,-1,0,1,2,3; ms can be +/- 1/2.
Note: for iii, I think you meant to write "l can be 0,1,2,3 or 4." t-4 doesn't make sense to me.
Which of the following sets of quantum numbers are not allowed. For each incorrect set, state why it is incorrect. For each correct set, name the atomic orbital.
i. n=4, l=3, ml =2, ms =-1/2
ii. n=2, l=1, ml =-1, ms =-1
iii. n=5, l=-4, ml =2, ms =+1/2
can you guys help me
my answers
i = i don't know
ii = ms is incorrect it is suppose to be -1/2
iii= l is incorrect because when n=5 l can be 0,1,2,3,4 not t-4
