Covalent Bonding Molecular Vs. Ionic Compounds
I. Molecular Vs. Ionic • Covalent Bond: A chemical bond characterized by sharing of pairs of electrons between atoms. • Molecule: an electrically neutral group of two or more atoms held together by covalent chemical bonds. • Diatomic Molecule: Molecule of only two elements covalently bonded together; H2, N2, O2, F2, Cl2, Br2, I2 • Molecular Compound: Compound formed by two non-metals sharing pairs of electrons. • Characteristics of Molecular Compounds: See chart

II. Molecular Formulas • The chemical formula of a molecular compound; shows how many of each element a molecule contains. It does not tell you anything about the structure or arrangement of atoms. • H2O • CO2 • NH3
