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.

How many orbitals exist in the fourth principal energy level what are they and in what periods can they be found?
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
How many orbitals are there for each level and the number of electrons?
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
How many orbitals can there be in an f sublevel?
The maximum number of f orbitals in any single energy level in an atom is 7.
How many electrons can be placed in the second energy level?
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.
How many 2p orbitals are there and what is the number of electrons they can hold?
There are three 2p orbitals and each can hold a maximum of two electrons with opposite spins, for a total of 6 electrons. This is true of the p sublevel in any energy level, except for the first energy level, which does not have a p sublevel.

Explain the relationship between electrons orbitals and energy levels?
Briefly:The electrons are in orbitals, each orbital can take two electrons and each electron would have an opposite spin. Orbitals can have no electrons, one electron or be filled with two electrons.Orbitals are arranged in energy levels. However, even in the same energy level different orbitals will have different energy despite being in the same main energy level.The energy level nearest the nucleus has 1 orbital: 1sThe next energy level, the second energy level has four orbitals: 2s and three p orbitals. The 2p orbitals have more energy than the 2s orbital. The third energy level has 3s x1; 3p x 3 and 3d x 5 however, the 3d orbitals have an energy which actually places them in the fourth energy level between 4s and 4p. It gets complicated.
How many d orbital can there be in an energy level?
The d sublevel contains 5 orbitals
