| element | 82_a pure substance that cannot be seperated into simpler substances by physical or chemical means |
| pure substance | 82_a substance in which there is only one type of particle |
| metals | 85_elements that are shiny and are good conductors of thermal energy and electric curent as well as being malleable and ductile |
| nonmetals | 85_elements that are dull (not shiny) and are poor conductors of thermal energy and electric current |
| metalloids | 85_called semiconductors; elements that have properties of both metals and nonmetals. |
| compound | 86_a pure substance composed of two or more elements that are chemically combined and cannot be broken apart by physical meansex. Sodium chloride NaCl = table salt) |
| mixture | 90_a combination of two or more substances that are not chemically combined; each substance retains their own chemical identity and can be physically seperated (like a piece of granite) |
| solution | 92_a mixture that appears to be a single substance but is composed of particles of two or more substances that are evenly distributed amongst each other (homogenous mixtures) |
| solute | 92_the substance that is dissolved |
| solvent | 92_the substance in which the solute is dissolved |
| soluble | 92_the ability to dissolve into a homogenous mixture (solution) |
| insoluble | 92_not able to be dissolved or form a solution, but instead forms a mixture that is not homogenous |
| concentration | 94_the measured amount of solute dissolved in a solvent, expressed in grams of solute per milliliter of solvent |
| solubility | 94_the amount of solute needed to make a saturated solution using a given amount of solvent at a certain temperature, expressed in terms of grams of solute per 100mL of solvent |
| suspension | 96_a mixture in which particles of a material are dispersed throughout a liquid or gas but are large enough to settle out (heterogenous mixtures) ex air in the atmosphere and nail polish |
| colloid | 97_a mixture in which the particles are dispersed throughout but are not heavy enough to settle out (jello, milk) |
