CHEM 0110 Chapter Notes - Chapter 2: Nuclide, Benzene, Robert Andrews Millikan
Document Summary
Atomic theory - an explanation of the structure of matter in terms of different combinations of very small particles. Atomic symbol - one or two letter notation used to represent an atom corresponding to a particular element (first letter capitalized) Atom - extremely small particle of matter that retains its identity during chemical reactions. Element - type of matter composed of only one kind of atom. Compound - type of matter composed of atoms of two or more elements chemically combined in fixed proportions. Chemical reaction - the rearrangement of the atoms present in the reacting substances to give new chemical combinations present in the substances formed by the reaction. Law of multiple proportions - when two elements form more than one compound, the masses of one element in these compounds for a fixed mass of the other element are in ratios of small whole numbers.
