principal energy level (n)= 3 Number of orbitals per level(n2)= 9 it equals 9 because it is n2 (32=9) n=1. 1 orbital n=2. 4 orbitals n=3. 9 orbitals n=4. 16 orbitals n=5. 25 orbitals n=6. 36 orbitalsn=7. 49 orbitals
In any orbital the maximum number of electrons is 2 of opposite spin. The following is a list of the different types of orbitals and the maximum nuber of electrons each type can contain. s-orbitals: one orbital, containing 2 electrons p-orbitals: three (px, py, pz) containing 6 in total d-orbitals: five, containing 10 f-orbitals: seven containing 14
The principal energy level is three, so there are three sublevels: 3s, 3p, and 3d. S,P and D
Its Principal quantum no is 2
There is one s orbital and three p orbitals and five d orbitals in the third energy level.

one
One only - 1s.
One only - 1s.
d
16 orbitals in the 4th energy level. One s orbital, three p orbitals, five d orbitals, seven f orbitals Elements where the 4th principal energy level are filled are:- period 4 4s and 4p (starting with potassium) period 5 4d starting with Yttrium Lanthanides 4f starting with cerium
The number of orbitals in electron shells are: One s orbital three p orbitals 5 d orbitals 7 f orbitals every shell has an s orbital, only shells 2 and above have p orbitals, only shells 3 and above have d orbitals only shells 4 and above have f orbitals. Each orbital can hold a maximum of 2 electrons. Level by level the orbitals 1s (one) 2s, 2p(three) 3s, 3p, 3d (five) 4s, 4p, 4d 4f(seven) In a shell where they are possible, all three p orbitals have the same energy, all 5 d orbitals have the same energy and all seven f orbitals have the same energy. I do not like the idea of saying there is a maximum-- an orbital is a solution to the energy levels in a hydrogen atom. You simply cannot have less than 3 p orbitals for instance.

3. Orbitals are filled one electron at a time, putt ting electrons into the lowest energy orbitals first. When there are degenerate orbitals ( having the same energy e.g. p and d orbitals) they tale one un paired electron each first and then and then any extra electrons are added into a half filled orbital to make a spin pair. P has a configuration of [Ne] 3s2 3p3 and there are only three p orbitals ( at any energy level)
All the orbitals contain one electron, with the same spins.
