The Total Number of Orbitals Associated With the Third Shell Will Be_______

The number of orbitals in the n^th shell can be calculated by the following formula;

number of orbitals = n²

We have to find the number of orbitals in the third shell.

Here, n = 3

number of orbitals = n²

= 3² = 9

Here, the third shell contains two s – orbital, three p – orbitals and five d- orbitals.

The total number of orbitals associated with the third shell will be___9____.
