| chemical property | characteristic that describes chemical change |
| atom | smallest prticle, has the chemical properties of that element |
| chemical reaction | 2 or more substances form a new substance |
| compound | substance of 2 ore more elements |
| crystal | solid; linked in geometric shapes |
| element | cannot be separated; compased of one type of atom |
| emulsion | dispersion of tiny particles in a liquid |
| endothermic | heat is absorbed in chemical reactions |
| exothermic | heat is released in chemical reaction |
| gas | physical state having definite volume/shape |
| liquid | physical volume but no shape |
| matter | substances are made of this |
| mixture | each substance retains own chemical physical properties |
| molecule | smallest unit of a compoudn; retains chemical properties of teh compound |
| periodic table | arrangement of chemical elements based on their atomic numbers |
| physical property | observable characteristic: shape, color texture, density, solubility, mass, volume... |
| product | substance formed as a result of a chemical reaction |
| reactants | substances that combine in a chemical reaction |
| solid | substance has volume and shpae with molecules held tightly together |
| solution | mixture when atoms/molecules dissolve;evenly disburse |
| volume | amount of space taken up by matter |
| substance | constant composition;substance is the same |
| homogenous materials | contains only one phase |
| heterogenous mixtures | more than one phase, can be separated physically |
| amorphous | atoms arranged without shape;haphazardly |
| solvent | liquid that dissolves the substance |
| solute | substance that was dissolved |
| electorlysis | using electricity to bread a compound into its base elements |
| sublimation | solid to gas directlly |
| plasma | gas so hoti is it ionized, found on the sun |
