Document Summary

Topics included: matter and energy, atoms, ions, and molecules, atomic structure, chemical bonding, bonding theories, intermolecular forces, stoichiometry, aqueous solutions, thermochemistry, properties of gases. Ions: atoms that have a positive or negative charge: physical change: X = elemental symbol: a one- or two-letter symbol to identify the type of atom. Z = atomic number: the number of protons in the nucleus and determines the identity. A = mass number: the total number of nucleons (protons and neutrons) in the nucleus: be sure to know the periodic table. Chemical formula: empirical formula: subscripts represent the simplest whole-number ratio, h1o1 ho, molecular formula: shows how many elements are in one molecule, h2o2, structural formula: shows the number of atoms and bonds between them, h-o-o-h. The mole: si unit for quantity of a substance, 1 mole of particles = 6. 022 x 10^23 avogadro"s number, this can be used as a conversion factor.
