| 3 characteristics of a covalent bond | 1. forms between 2 metals 2. softens compounds 3. can be solid, liquid or gas |
| 3 characteristics of a ionic bond | 1. between metal & non metal 2. always make a solid 3. rigid brittle compounds |
| what is an ion | an atom or molecule with a net electrical charge due to the loss or gain of one or more electrons |
| How does an atom become a positive ion | it loses or gains the number of electrons |
| What families on the periodic table do this | helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, magnesium, aluminum |
| What is an isotype? | each of two or more forms of the same element that contain equal numbers of the nuetrons in their nucleus. |
