The name(s) of the subshells are s,p and d
Each orbital in an atom consists of 4 quantum numbers
n is the principal quantum number.
l is the angular momentum / azimuthal quantum number
ml, the magnetic quantum number
ms, the electron-spin quantum number
Value of n: positive integer
value of l: s = 0, p = 1, d = 2, f = 3 , ..(n-1)
ml value: between -l to + l
ms value: +1/2 or -1/2
n=3, then the possible value of l is a maximum of n-1 = 3-1 = 2
So the value of subshells = 0,1 and 2
