Which of the following gives the correct possible

values of / for n = 4?

O 0, 1, 2, 3

-4, - 3, - 2,-1,0, 1, 2, 3, 4

O 0, 1, 2, 3, 4

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
