Atoms, Molecules, and Ions (Chemistry)

Recall cards on atoms, molecules, and ions: early ideas in atomic theory (Dalton's postulates; the laws of conservation of matter, definite proportions, and multiple proportions); the evolution of atomic theory (Thomson's cathode rays and the electron; Millikan's oil drop experiment; the plum pudding model; Rutherford's gold foil experiment and the nucleus; the proton, neutron, and isotopes); atomic structure and symbolism (the atomic mass unit; atomic number, mass number, and neutron count; isotope notation; ions, cations, and anions; average atomic mass); chemical formulas (molecular, empirical, and structural formulas; molecular models); the periodic table (the periodic law; periods and groups; metals, nonmetals, and metalloids; the element families); molecular and ionic compounds (ionic and covalent bonds; ion charges; monatomic and polyatomic ions); and chemical nomenclature (naming ionic compounds and the Stock system, binary molecular compounds, and acids).
