Which statement about the four quantum numbers which describe electrons in atoms is incorrect?

Q. Which statement about the four quantum numbers which describe electrons in atoms is incorrect?

A.            n = principal quantum number, n = 1, 2, 3, ……

B.            l = subsidiary (or azimuthal) quantum number, l = 1, 2, 3, … , (n+1)

C.            ml = magnetic quantum number, ml = (-l), …. , 0, …. , (+l)

D.            ms = spin quantum number, ms = +1/2 or -1/2.

Answer: l = subsidiary (or azimuthal) quantum number, l = 1, 2, 3, … , (n+1)
