well basically the idea behind orbitals is that in the s orbital, there is one orbital in which two electrons can fit themselves. In the p orbitals, in one section there are three orbitals, each of which can fit two electrons, therefore fitting 6 electrons. Finally, you can get into d and f orbitals, which hold 10 and 14 electrons, respectively. Look in a Chem book if you really want to know.
