The atomic states with principal quantum number 4 can have orbital angular momentum quantum numbers from -4 to 4. Hence there are 9 possible values of the orbital angular momentum quantum number. Each electron can have spin +1/2 or -1/2, so each of the states specified by a given orbital angular momentum quantum number can have at most two electrons in the state without violating Pauli's exclusion principle.
So, in sum, there are 18 possible states for an electron with principal quantum number 4.
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
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
There are one 3s orbital, three 3p orbitals, and five 3d sublevels.
The third energy level of an atom can hold eight electrons.
8 electrons. The second energy level (n=2) has 4 orbitals. One s orbital and three p orbitals. Each orbital can hold 2 electrons of opposite spin.
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
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.
There is one s orbital and three p orbitals and five d orbitals in the third energy level.

In the second energy level, there are four orbitals - one 2s orbital and three 2p orbitals.
There are four energy sublevels in the fourth energy levels: 4s, 4p, 4d, and 4f.
There are two sublevels in the second principle energy level. The s sublevel has one orbital and the p sublevel has 3, for a total of 4 orbitals.
