A hybrid orbital is an orbital formed by the combination of two or more atomic orbitals. The resulting orbital has a different shape and energy than the component orbitals that form it. Hybridization is used to model molecular geometry and to explain atomic bonding.

Example

The orbitals that form around berylium in BeF2 are a combination of s and p orbitals called sp hybrid orbitals.
