| A | B |

| what are stable atoms? | atoms that will not react or form bonds with other atoms. |
| what are isotopes? | forms when it has lost or gained neutrons and has same # of p(+) but diff. atomic mass then listed on periodic table. |
| what are chemical reactions? | they occur when bonds are formed or broken to recombine into different/new substances. |
| what is a compound? | a substance composed of atoms two or more diff. elements that are chemically combined. |
| the attractive force between 2 ions of opposite charges is known as? | ionic bond |
| how do ionic bons form? | an atom that gains or loses electorns. is electricaly charged. |
| how do covalent bonds form? | atoms combine with other atoms only when the resulting compound is more stable then the individual atoms. |
| what equation do you use to calculate the # of neutrons in an atom? | -p=n |
| how do isotopes form? | if # of neutrons changed, the atomic mass changes and the atom forms. |
| what is a covalent bond? | a chemical bond that shares electrons between atoms. |
