22. Pure Substances Composition is the same throughout and does not vary from sample to sample. CANNOT be broken down by physical changes Can be an element or compound.

23. Element Definition: substances in their simplest forms Cannot be broken down by a physical or chemical change Found on the periodic table Made up of one type of atom

24. Examples of Elements: Hydrogen Carbon Lithium Gold What are two other examples of elements not listed above? What do all elements have in common?

25. Compound Definition: substance formed by the chemical combination of two or more elements can be broken into simpler substances by a chemical change + = Compound

26. A compound is always composed of the same elements in the same proportions. In other words, Carbon Dioxide (CO 2 ) is always composed of 1 atom of C and 2 atoms of O. If there are different amounts of carbon or oxygen, it is no longer carbon dioxide. Law of Definite Proportions

27. More Examples of Compounds

28. Mixture Definition: two or more pure substances (elements or compounds) that are mixed together but NOT joined chemically NOT a pure substance Examples: The air we breath, gasoline for cars, the sidewalk on which we walk

29. Homogeneous Mixtures Uniform in composition and appearance Same proportion of components throughout Consists of two or more substances in the same phase Also called solutions Uniform in composition and appearance Same proportion of components throughout Consists of two or more substances in the same phase Also called solutions

30. Heterogeneous Mixtures variable appearance and composition
