| Bonds | ||
| #1 | Differentiate between single, double and triple bonds in terms of bond length and strength. | single bonds are the longest and weakest; as more bonds are added they become shorter and stronger. |
| #2 | Differentiate between melting points of ionic and molecular compounds. | ionic compounds have higher melting points than molecular compounds |
| #3 | Electronegativity and number of atoms determines what characteristic of a molecule? | polarity |
| #4 | Which diatomic molecule is joined by a triple covalent bond? | nitrogen |
| #5 | What property contributes to the unique characteristics of water? | polarity |
| Polarity | ||
| #1 | According to the VSEPR theory, molecules adjust their shapes for what reason? | to keep the valence electrons as far apart as possible |
| #2 | The attraction of the more negative end of a molecule for the more positive end of another molecule is known as... | dipole interaction |
| #3 | The phenomenon where a molecule can be diagrammed in more than one way is known as | resonance |
| #4 | Condition when electrons are shared unequally | polar |
| #5 | Equal sharing of electrons creates a molecule that is ______________. | non-polar |

| #1 | tetraphosphorus monoxide | P4O |
| #2 | methane | NH3 |
| #3 | ammonnia | NH3 |
| #4 | octane (gasoline) | C8H18 |

| #1 | Atoms with greatly differing electronegativity values are expected to form what type of bonds? | ionic |
| #2 | The correct Lewis structure for a fluorine atom in a molecule of F2 shows | |
| #3 | 3 atoms bonded to central atom and 1 lone pair of electrons | trigonal pyramidal |
| #4 | 6 atoms bonded to the central atom and no lone pairs of electrons | octahedral |
| #5 | 5 atoms bonded to the central atom and no lone pair of electrons | trigonal bipyramidal |
