| element | pure substance that cannot be seperated |
| pure substance | only one type of particle |
| physical properties | boiling pt., melting pt., density,... |
| chemical properties | ability to change into a new substance with different properties |
| 3 major categories of elements | metals, nonmetals, metalloids |
| compounds | has 2 or more element that are combined chemically |
| mixtures | combination of 2 or more substances that are not chemically combined |
| solution | mixture of 1 substance but combined with particles of 2 or more substances |
| solute | substance that is dissolved to form a solution |
| solvent | substance in which solute is dissolved to form a solution |
| concentration | measure of the amount of solute dissolved in a solvent |
| solubility | amount needed to make a saturated solution using solvent at certain temperature |
| suspension | mixture that particles are scattered throughout a gas or liquid |
| colloid | mixture where particles are scattered throughout but are heavy enough to settle out |
| metals | element of shiny,ductile, and maleable and are good conductors of thermal energy and electric current |
| nonmetals | elements that are not shiny and are poor conductors of thermal energy and electric current |
| metalloids | elements that have both metal and nonmetal; semiconductors |
