Answer:
b. 3
Explanation:
Each level has its electrons distributed in different sub-levels, which can be of four types: s, p, d, f
In each sub-level, there is a certain number of orbitals that can contain a maximum of 2 electrons each.
For example, the sub-level s can only contain 2 electrons, therefore it has only one orbital.
The sub-level p can contain 6 electrons, and since each orbital can contain a maximum of 2 electrons it means that the sub-level p has 3 orbitals.
