n = 2
l = n - 1 = 2-1 = 1
ml = -l to +l = -1, 0 , +1
ms = +1/2 or -1/2
all of the designations (n, l, ml, ms) of the quantum numbers associated with the orbitals in the 2p subshell are
(2 , 1 , -1 , -1/2) , (2 , 1 , -1 , +1/2) , (2 , 1 , 0 , -1/2) , (2 , 1 , 0 , +1/2),
(2 , 1 , +1, -1/2) and (2 , 1 , +1 , +1/2)
