| When an atom has a full valence shell, will it react easily and form bonds? | No |
| Where are the valence electrons found? | Outermost level / shell |
| When an atom's valence shell is almost empty, it will ______ electrons to stabilize. | Lose / Get rid off / Give away |
| When an atom's valence shell is almost full, it will ______ electrons to stabilize. | Gain / Take in / Steal |
| When an atom's valence shell is half full / half empty, it will _______ electrons to stabilize. | Share |

| Have 4 valence electrons so will most likely share electrons. Can either lose or gain 4. Charge can be + or - 4 | Group 4: Carbon Family |
| Metals are found on the ____ side of the Periodic Table. | Left |
| Nonmetals are found on the ____ side of the Periodic Table. | Right |
| Transition metals are found in the ____ of the Periodic Table. | Center / Middle |
| A bond formed by transferring electrons | Ionic |
| A bond formed by sharing electrons | Covalent |
| If the shared electrons are NOT EVENLY spaced out around the atoms, it is a ___ bond. | Polar Covalent |
| If the shared electrons are evenly spaced out around the atoms, it is a ____ bond. | Nonpolar Covalent |
| Why do elements form compounds? | To stabilize (have full outer shells) |
| Two elements chemically combine | Compound |
| Two elements physically combine | Mixture |
| Which three groups are more likely to lose electrons to form bonds? | 7, 6 & 5 |
| Which three groups are more likely to gain electrons to form bonds? | 1, 2 & 3 |
| Why are the noble gasses unreactive? | Full valence shell |
| If the electronegativity difference is <.5 | Nonpolar covalent bond |
| If the electronegativity difference is > .5 but < 1.7 | Polar covalent bond |
| If the electronegativity difference is > or = 1.7 | Ionic bond |
