| Bondenergy | | an electron pair found in the space between two atoms. |
| Triplebond | | the energy change occurring when separated gaseous ions are packed together to form an ionic solid. |
| Latticeenergy | | a model whose main postulate is that the structure around a given model atom in a molecule is determined principally by minimizing electron-pair repulsions. |
| Lonepair | | a model which assumes that a molecule is composed of atoms that are bound together by sharing pairs of electrons using the atomic orbitals of the bound atoms. |
| Singlebond | | a property of a molecule whose charge distribution can be represented by a center of positive charge and a center of negative charge. |
| Doublebond | | the energy required to break a given chemical bond. |
| localizedelectronmodel | | the electrostatic attraction between oppositely charged ions |
| Dipolemoment | | an electron pair that is localized on a given atom, an electron pair not involved in bonding. |
| VSEPR | | ions containing the same number of electrons |
| Ionicbonding | | a bond in which three pairs of electrons are shared by two atoms |
| Lewisstructure | | the distance between the nuclei of the two atoms connected by a bond, |
| Resonance | | a condition occurring when more than one valid Lewis structure can be written for a particular molecule. |
| Covalentbonding | | is the energy of interaction between a pair of ions |
| Octetrule | | a diagram of a molecule showing how the valence electrons are arranged among the atoms in the molecule. |
| Isoelectronicions | | a bond in which one pair of electrons is shared by two atoms |
| Molecularstructure | | the charge assigned to an atom in a molecule or polyatomic ion derived from a specific set of rules. |
| Bondlength | | a type of bond in which electrons are shared by atoms. |
| Formalcharge | | the three-dimensional arrangement of atoms in a molecule |
| Bonding | | a covalent bond in which the electrons are not shared equally because one atom attracts them more strongly than the other. |
| Polarcovalentbond | | the tendency of an atom in a molecule to attract shared electrons to itself. |
| Coulomb'slaw | | the observation that atoms of nonmetals tend to form the most stable molecules when they are surrounded by eight electrons (to fill their valence orbitals). |
| Electronegativity | | a bond in which two pairs of electrons are shared by two atoms |
