When one s and one p orbital belonging to the same main shell of an atom mix together to form two new equivalent orbitals, the type of hybridization is called sp hybridization. The new orbitals formed are called sp hybrid orbitals.

They are collinear with an angle of 180⁰.

Each of the hybrid orbitals formed has 50% s-character and 50% p-character.

The remaining two p-orbitals which do not participate in hybridization remain as such.

If these are half-filled, they may form bonds with other atoms having half-filled atomic orbitals.
