There are 1 orbital in the S orbital

There are 3 orbitals in the P orbital

There are 5 orbitals in the D orbital

2 electrons maximun

2n^2 2(2)^2= 2(16)= 32

the N stands for energy level

Therefore, the maximum number of electrons that can occupy a principal energy level is given by the formula 2n2. 32
