Document Summary
Section 1 atomic theory of matter. If there is a metal or a polyatomic ion in a compound, it is generally ionic. Nonmetal: provided the basic theory: all matter whether element, compound, or mixture is composed of small particles called atoms. Postulates of dalton"s atomic theory: atomic theory: an explanation of the structure of matter in terms of different combinations of very small particles, 1. Atom: an extremely small particle of matter that retains its identity during chemical reactions: 2. An element: a type of matter composed of only one kind of atom, each atom of a given kind having the same properties. Thus, the atoms of a given element have a characteristic mass: 3. A compound: a type of matter composed of atoms of two or more elements chemically combined in fixed proportions. The relative numbers of any two kinds of atoms in a compound occur in simple ratios.
