Atom is made up of neutrons, protons, and electrons. Molecules are groups of 2 or more atoms held together by chemical bonds. Chemical bonds are due to electron interactions ? Electronegativity = ability of an atom to attract electrons ? Bond Types: o Ionic ? transfer of electrons from one atom to another (different electronegativities)
