Expert Solution
Step 1

The number of microstates available for a configuration can be calculated using the formula 

Number of microstates=(Number of electron positions)!(Number of electrons available)!(Number of electron positions-Number of electrons available)!

The variable s represents the spin quantum number of the electron and its magnitude is 1/2.

The variable l represents the azimuthal quantum number. It represents the orbital angular momentum and defines the shape of the orbital. Its value ranges from 0 to n-1 value, where n is the principal quantum number. The value of l  0, 1, 2, 3 represents the s, p, d, and f orbitals respectively.
