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
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.
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
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.
There are one 3s orbital, three 3p orbitals, and five 3d sublevels.
