|
Term
|
Definition
| a type of bonding where the electrons are shard by atoms |
|
|
Term
|
Definition
a covalent bond in which the electrons are not shared equally because one atom attracts them more strongly than the other |
|
|
Term
|
Definition
| the tendency of an atom in a molecule to attract shared electrons to itself. |
|
|
Term

| ions containing the same number of electrons |
|
|
Term
|
Definition
The energy change occurring when seperated gaseous ions are packed together to form an ionic compound |

Definition
| a bond in which three pars of electrons are shared by two atoms |
|
|
Term
|
Definition
a model that 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. |
|
|
Term
|
Definition
| an electron pair this is localized on a given atom; an electron pair not involved in bonding. |
|
|
Term
|
Definition
| a electron pair found in the space between two atoms. |
|
|
Term
|
Definition
| the observation that atoms of nonmetals tend to form the most stable molecules when they are surrounded by eight electrons |
|
|
Term
|
Definition
| a condition occurring when more than one valid Lewis Structure can be written for a particular molecule. The actual electronic structure is not represented by any on of the lewis structures but by the average of all of them. |

Term
|
Definition
| the charge assigned to an atom in a molecule or polyatomic ion derived from a specific set of rules. |

Valence Shell Electron-Pair Repulsion
(VESPR)
Model |
|
Definition
| a model whose main postulate is that the structure around a given atom in a molecule is determined principally by minimizing electron-pair repulsions. |
