    There are 4 quantum numbers that can be used to describe the space of highest probability an electron resides in.

    First quantum number is the principal quantum number - n, states the energy level.

    Second quantum number states the angular momentum quantum number - l,

    states the subshell and the shape of the orbital

    values of l for n energy shells are from 0 to n-1

    third is magnetic quantum number - m, which tells the specific orbital.

    fourth is spin quantum number - s - gives the spin of the electron in the orbital

    here we are asked to find l for 3p1

    n = 3

    and values of l are 0,1 and 2

    for p orbitals, l = 1

    therefore second orbital for 3p¹ is 1.
