A | B |
element | a pure substance that cannot be separated or broken down into simpler substances by physical or chemical means |
pure substance | a substance in which here is only one type of particle; includes elements and compounds |
metalloids | elements that have properties of both metals and nonmetals; sometimes referred to as semiconductors |
metals | elements that are shiny and are good conductors of thermal energy and electric current; most metals are malleable and ductile |
nonmetals | elements that are dull and are poor conductors of thermal energy and electric current |
compound | a pure substance of two or more elements that are chemically combined |
mixture | a combination of two or more substances that are not chemically combined |
homogeneous mixture | a combination of substances in which the appearance and properties are the same throughout |
solute | the substance that is dissolved to form a solution |
solution | a mixture that appears to be a single substance but is composed of particles of two or more substances that are distributed evenly amongst each other |
solvent | the substance in which a solute is dissolved to form a solution |
alloys | solid solutions of metals or nonmetals dissolved in metals |
concentration | a measure of the amount of solute dissolved in a solvent |
saturated solution | a solution that contains all the solute it can hold at a given temperature |
solubility | the ability to dissolve in another substance; more specifically, the amount of solute needed to make a saturated solution using a given amount of solvent at a certain temperature |
heterogeneous mixture | a combination of substances in which different components are easily observed |
suspension | a mixture in which particles of a material are dispersed throughout a liquid or gas but are large enough that they settle out |
colloid | a mixture in which the particles are dispersed throughout but are not heavy enough to settle out |
