| A | B |
|---|
| ion | at atom that has an uneven number of protons/electrons |
| cation | atom that has more protons than electrons |
| anion | atom with more electrons than protons |
| isotope | atoms with differing numbers of neutrons but same number of protons |
| molecule | two or more atoms join together |
| compound | molecule that contains at least 2 different elements |
| chemical bonds | attraction between atoms to join together |
| chemical formula | way of expressing the number and types of atoms in a molecule using symbols |
| chemical reaction | changes in matter where chemicals bonds are broken, rearranged, and reformed |
| chemical equation | illustrates a chemical reaction, showing the breakdown of reactants and the formation of the products |
| reactants | the molecules/compounds broken down in reaction (left side) |
| products | molecules/compounds created during reaction (right side) |
| photosynthesis | process in which some organisms (plants and some bacteria) take in carbon dioxide and water to create glucose and oxygen using energy from the sun to fuel the reaction. |
| Law of conservation of matter | matter can never be created nor destroyed, amount of matter remains constant. |
| balanced equation | number of atoms in reactants equal number of atoms in products |
