  1. Chemical Formulas COVALENT/MOLECULAR COMPOUNDS

  2. Chemical Formulas • Chemical formula - a symbolic representation of chemical compounds; contains: • elements in compound (symbols) • # of atoms in each element • NaCl – sodium-one atom & chlorine-one atom • H2O – Hydrogen-2 atoms & oxygen-one atom

  3. Types of Chemical Formula • Ionic • Giving and Taking of Electrons • Covalent • Share of electrons

  4. Covalent – non-metal and non-metal → sharing of electrons (e-) Types of Chemical Formulas Oxidation numbers do NOT apply

  5. Naming Molecular/CovalentCompounds • anion (-) + anion (-) • Name is determined by the subscript • CO2 • Carbon Dioxide • N2O • Dinitrogen monoxide • Naming Covalent Compounds • Begin with name of first Anion • Elements name + prefix determined by the subscript • NEVER use “mono” • End with name of second Anion • Elements name + prefix determined by the subscript

  6. Writing Formulas and Naming Covalent Compounds

  7. Acid Compounds • Two Types of Acids: • Hydrogen + • Binary (single anion) • Ternary (negative polyatomic ion)

  8. Binary Acids • Examples • HCl hydrogen + chlorine Hydrochloric • HBr • Naming Binary Acids • Change the first element - hydrogen to “hydro” – • Change the 2nd element’s ending to –”ic”

  9. Writing Binary and Ternary Formulas
