As per my knowledge an electron revolving in 5d subshell has quantum numbers set(in usual order)as:-
l=0,1,2,3,4                              (any one)
m=-4,-3,-2,-1,0,1,2,3,4            (any one)
s==1/2 or -1/2                        (any one)
but in revision test my answer went wrong .Can you please tell me ,whether i was actually wrong or the test had an inbuilt incorrect answer?

Expert Answer:

As you have mentioned that the electron is revolving in 5d subshell so the quantum number set for that will be as follows:
n = 5
l = 2
m = -2, -1, 0, +1, +2
s = +1/2 or -1/2
