| non-metal | do not conduct electricity and heat are britle |
| compound | mixture with ionic bonds also can not be broken apart |
| mixure | mixture without ionic bonds and can be seperated |
| chemical property | property of substace you haave to change it to see |
| phisical property | property you can see without changing the substance |
| chemical change | change of a substance that can not be reversed or you can not salvige the leftover of that experiment and get the same subtance back |
| Phisical change | change of a substance to where it is not chemicaly broke down ex:erotion |

| petrochemicals | substances that are oil based products |
| Ion | an atom with a loss or gain of an electron |
| Ionic bond | Abond between atoms where one atom loses an electon to fill up an other atomes valence circle then they are bonded |
| convolent bond | a bond between atoms where they share an electron |
| Reactant | Part of chem reaction |
| Chemical reaction | When two or more substances react to each other and made a new substance |
| Chemical equation | A chemical reaction writen down with chemical sybles |
| Product | the result of the chem. reaction |
| reaction rate | the speed of how long it take for chem. reaction to happen |
