Document Summary

Chapter 1: matter and energy: an atomic perspective. Smallest particle of an element that retains the chemical characteristic of that element: element. Substance that cannot be separated into simpler substances by a chemical process: compound. Substance composed of proportions of two or more element chemically bonded together. Can be separated by chemical processes into component elements. Scienti c laws: law of de nite proportions. Compounds always contain the same proportion of their component elements: law of constant composition. All samples of a particular compound have the same elemental composition no matter their source: law of multiple proportions. An element may combine in di erent ratios with another element forming di erent compounds. Chemical formulas: notation to show elemental composition of a pure substance, ratio using the symbols of the element, subscripts represent the relative number of atoms of each element in the substance. Classes and properties of matter: matter. Anything that has mass and occupies space: chemistry.
