1 Chemistry 1 of 25 Elements and Take two pounds of sugar, two cups of boiling water, and one quarter teaspoon of cream of tartar. Add food coloring and you have the sticky, sweet concoction known as cotton candy. You will learn how substances are classified as elements or compounds. 2 of 25 1
2 3 Elements and > Distinguishing Elements and Distinguishing Elements and How are elements and compounds different? 3 of 25 Elements and > Distinguishing Elements and An element is the simplest form of matter that has a unique set of properties. A compound is a substance that contains two or more elements chemically combined in a fixed proportion. 4 of 25 2
3 Elements and > Distinguishing Elements and can be broken down into simpler substances by chemical means, but elements cannot. 5 of 25 Elements and > Distinguishing Elements and Breaking Down A chemical change is a change that produces matter with a different composition than the original matter. When table sugar is heated, it goes through a series of chemical changes. 6 of 25 3
4 Elements and > Distinguishing Elements and The final products of these chemical changes are solid carbon and water vapor. The following diagram summarizes the process. 7 of 25 Elements and > Distinguishing Elements and Properties of In general, the properties of compounds are quite different from those of their component elements. When the elements sodium and chlorine combine chemically to form sodium chloride, there is a change in composition and a change in properties. 8 of 25 4
5 Elements and > Distinguishing Elements and Chlorine is used to kill harmful organisms in swimming pools. 9 of 25 Elements and > Distinguishing Elements and Sodium is stored under oil to keep it from reacting with oxygen or water vapor in the air. Sodium vapor produces the light in some street lamps. 10 of 25 5
6 Elements and > Distinguishing Elements and Sodium Chloride (commonly known as table salt) is used to season or preserve food. 11 of 25 Elements and > Distinguishing Substances and Mixtures Distinguishing Substances and Mixtures How can substances and mixtures be distinguished? 12 of 25 6
7 Elements and > Distinguishing Substances and Mixtures If the composition of a material is fixed, the material is a substance. If the composition of a material may vary, the material is a mixture. 13 of 25 Elements and > Distinguishing Substances and Mixtures This flowchart summarizes the process for classifying matter. 14 of 25 7

These chemical symbols were used in earlier centuries. 20 of 25 10
