A sublevel is an electron orbital. Sublevels are designated s, p, d or f.

These sublevels or orbitals have characteristic shapes which can be used to explain and predict the chemical bonds that atoms can form. 

 

S orbitals can hold a maximum of 2 electrons, p a maximum of 6 electron, d a maximum of 10 electrons, and f a maximum of 14 electrons.
