In the second energy level, there are four orbitals - one 2s orbital and three 2p orbitals.
There are three p orbitals in all levels 2 and above. these are the px, py and pz orbitals, the (suffix is the direction - px lies along the x axis). In the 5th level they will be 5px, 5py, 5pz

1 orbital with 2 atoms on it
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
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
