Atomic theory
Ultimate constitution of matter. Nature and phases of ultimate particles:
atoms, ions, anions, kations, electrons. Atomicity. Relationship of mass to
chemic properties of bodies. Laws of chemic combination: weight, defini
proportions, equivalence, multiple proportions. Laws of volume for gases.
Simple or compound nature of chemic elements. Molecules. Atomic and
molecular weights; methods of determination. Atomic and molecular volumes
Laws fundamental to atomic theory; see also 541.9 Classification, periodic law.
