| Calorie | the amount of heat energy required to raise a temperature of 1 g of water by 1 degree C |
| Chemical Bond | An atttractive force that holds together atomes, ions, or groups of atoms in a molecule or combination |
| Chemical reaction | Chemical transformation or change; the interaction of chemical entities |
| Compound | A substance consisting of two or more elements in a fixed ration |
| Covalent Bond | A type of strong chemical bond in which two atoms share one or more pair of valence electrons |
| Element | The smallest particle of a substance that retains all the properties of the substance and is composed of one or more atoms |
