Pi Bonds

Covalent chemical bonds formed by the side-to-side overlap of atomic orbitals, allowing for electron sharing in double and triple bonds.

Hybridization

A concept in chemistry that describes the mixing of atomic orbitals into new hybrid orbitals, suitable for the pairing of electrons to form chemical bonds.

Atom
