| Question | Answer |
| tetrahedral structure | CH4 4 triangular planes |
| trigonal planar structure | all four atoms in the same plane (120 degrees) |
| linear structure | all atoms in a line |
| bond angle | to describe a "bent or V" structure more precisely |
| molecular structure | the three-dimensional arrangement of atoms in a molecule |
| resonance structures | different structures of the same molecule |
| resonance | when more than one Lewis structure can be drawn for a molecule |
| double bond | two atoms sharing two pairs of electrons |
| single bond | two atoms sharing one electron pair |
| unshared pairs | electrons that are not involved in bonding |
| bonding pair | two valence electrons are shared |
| octet rule | surrounded by 8 electrons |
| Lewis structure | representation of a molecule that shows how the valence electron are arranged among the atoms in the molecule |
| dipole moment | area of molecule that is mostly positive and mostly negative |
| electronegativity | relative ability of an atom in a molecule to attracted shared electrons to itself |
| polar covalent bond | atoms are unequal enough so that unequal sharing of electrons results (.4-2.1) |
| covalent bonding | atoms share electrons |
| ionic compounds | metals reacts with a non-metal |
| ionic bonding | attractions among the closely packed, oppositely charged ions |
| bond energy | the energy required to break a bond |
| bond | a force that holds groups of two or more atoms together and makes them function as a unit |
| percent yield | comparison of theoretical and actual yield expressed as a percentage |
| theoretical yield | the amount of product calculated |
| limiting reactant | limits the amount of products that can be formed |
| stoichiometry | the process of using a chemical equation to calculate the relative masses of reactants and products involved in a reaction |
| mole ratios | conversion factors based on the balanced chemical equation |
| Molarity (M) | amount of solute in moles and amount of volume in liters (mol solute/L solution) |
