Back

A chemical bond formed by the sharing of electron pairs between atoms.

Front

Define electronegativity.

Back

The tendency of an atom to attract electrons towards itself in a chemical bond.

Front

What is a polar covalent bond?

Back

A type of bond where electrons are shared unequally between two atoms, resulting in partial charges.
