| Dot Diagrams | the symbol for the element in the center, surrounded by dots indicating the number of valence electrons. |
| atoms with 4 or fewer valence electrons will lose them to form positive ions | atoms with 5 or more valence electrons will gain enough to have 8 |
| step 1: F | write the electron configuration 1s^2 2s^2 2p^5 |
| step 2: F | decide if it gains or loses an electron F has 7 valence electrons so it will gain 1 electron. the ion formed is F -1 |
| step 3: F | use dots to represent the valence electrons |
| dot diagram of a positive ion | there will be no dots on this diagram |
| dot diagrams of negative ions | an x will be used to place the remaining dots |
