The 3rd period contains 2 of the 3 orbitals for the third sublevel. It has the s and p orbitals in it.
There are five d orbitals in one energy level. These orbitals are designated as dxy, dyz, dxz, dz2, and dx2-y2. Each d orbital can hold a maximum of 2 electrons.
6 electrons in 3 orbitals of p-sublevel: px, py and pz

All p sublevels contain three orbitals, including the 4p sublevel.
5 orbitals
7 Orbitals
There are a total of 9 orbitals within the 3s, 3p, and 3d sublevels of the third energy level. The 3s sublevel has 1 orbital, the 3p sublevel has 3 orbitals, and the 3d sublevel has 5 orbitals.
There are 7 orbitals in the f sublevel. These orbitals are designated as 4f, 5f, 6f, 7f, 8f, 9f, and 10f.
In an f sublevel, there can be a maximum of 7 orbitals. Each orbital can hold up to 2 electrons, resulting in a total capacity of 14 electrons within the f sublevel.
