π Bonds

Pi bonds occur when two lobes of an orbital on one atom overlap two lobes of an orbital on another atom and electron density is concentrated above and below the plane of the nuclei.

Molecular Orbital

A region of space in a molecule where an electron is likely to be found, formed by the overlap of atomic orbitals from bonded atoms.

Atomic Orbitals

Mathematical functions describing the probable location of an electron around an atom, instrumental in the formation of chemical bonds.

Sigma Bonding

A type of covalent bond where electrons are shared in an area directly between atoms, involving the overlap of atomic orbitals.
