There is one s orbital and three p orbitals and five d orbitals in the third energy level.

The first energy level contains one s orbital, which can hold up to two electrons.
In energy level three, there are four types of orbitals: s, p, d, and f. Specifically, the 3s and 3p orbitals are available, as well as the 3d orbitals, which start to fill at this energy level. The 3f orbitals do not exist in the third energy level; they begin in the fourth energy level. Thus, the total number of orbital types at energy level three is three: s, p, and d.

1st energy has 1 sublevel -- 1 orbital -- 2 electrons 2nd energy level has 2 sublevels -- 4 orbitals -- 8 e- 3rd energy level has 3 sublevels -- 9 orbitals -- 18 e- 4th energy level has 4 sublevels -- 16 orbitals -- 32 e- Notice the pattern? number of orbitals = energy level squared Number of electrons = 2x number of orbitals
In the second energy level, there are four orbitals - one 2s orbital and three 2p orbitals.
They can only have 1 S ORBITAL per energy level (1s, 2s, 3s...). Each S orbital consists of 2 electrons of opposite spin.

The first energy level can hold a maximum of 2 electrons, filling the 1s orbital. The second energy level can hold a maximum of 8 electrons, filling the 2s and 2p orbitals.
