    l = 0, 1, 2, 3

    m = - 3, - 2, - 1, 0, 1, 2, 3

    s = + 1/2 or - 1/2

    Explanation:

    The principal quantum number is denoted by n and which gives the size of the atomic orbital. It is given an integer value (e. g., n = 1, 2, 3 ...), and its value is never 0. The angular momentum quantum number/azimuthal quantum number describes the shape of the atomic orbital. l can take values from 0 to n-1. The magnetic quantum number, m distinguishes the orbitals available within a sub-shell. It can take values from - l to l including 0. The Spin Quantum Number s gives the angular momentum of an electron. Because angular momentum is a vector, the Spin Quantum Number (s) has both a magnitude (1/2) and direction ( + or - ). So, it can be - 1/2 or + 1/2.

    For the given value of n=4

    l = 0, 1, 2, 3

    m = - 3, - 2, - 1, 0, 1, 2, 3

    s = + 1/2 or - 1/2
