Electronegativity

A measure of the tendency of an atom to attract a bonding pair of electrons.

Covalent bond

A chemical bond that involves the sharing of electron pairs between atoms.

Dipole

A pair of equal and opposite electric charges or magnetic poles separated by a distance.

Molecular geometry

The three-dimensional arrangement of atoms in a molecule.

Bond length

The distance between the nuclei of two bonded atoms.
