|
|
Term
|
Definition
| A bond formed by the sharing of electrons between atoms |
|
|
Term

|
|
Term
|
Definition
| A molecule consisting of two atoms. |
|
|
Term
|
Definition
| A molecule that has two poles, or regions with opposite charges |
|
|
Term
|
Definition
| Intermolecular forces resulting from the attraction of oppositely charged regions of polar molecules |
|
|
Term
|
Definition
| Attractions between molecules caused by the electron motion on one molecule affecting the electron motion on the other through electrical forces; these are the weakest interactions between molecules |
|
|
Term
|
Definition
| A bond in which two atoms share two pairs of electrons |
|
|
Term
|
Definition
| The mixing of several atomic orbitals to form the same total number of equivalent hybrid orbitals |
|
|
Term
|
Definition
| Attractive forces in which a hydrogen covalently bonded to a very electronegative atom is also weakly bonded to an unshared electron pair of another electronegative atom |
|
|
Term
|
Definition
| A compound that is composed of molecules. |
|
|
Term
|
Definition
| A chemical formula of a molecular compound that shows the kinds and numbers of atoms present in a molecule of a compound |
|
|
Term
|
Definition
| An orbital that applies to the entire molecule |
|
|
Term
|
Definition
| A neutral group of atoms joined together by covalent bonds |
|
|
Term
|
Definition
| Solids in which all of the atoms are covalently bonded to each other |
|
|
Term
|
Definition
| A covalent bond in which the electrons are shared equally by the two atoms |
|
|
Term
|
Definition
| A covalent bond in which the bonding electrons are most likely to be found in sausage-shaped regions above and below the bond axis of the bonded atoms |
|
|
Term
|
Definition
| A covalent bond between atoms in which the electrons are shared unequally |
|
|
Term
|
Definition
| A molecule in which one side of the molecule is slightly negative and the opposite side is slightly positive |
|
|
Term
|
Definition
| A tightly bound group of atoms that behaves as a unit and has a positive or negative charge |
|
|
Term
|
Definition
| One of the two or more equally valid electron dot structures of a molecule or polyatomic ion |
|
|
Term
|
Definition
| A bond formed when two atomic orbitals combine to form a molecular orbital that is symmetrical around the axis connecting the two atomic nuclei |
|
|
Term
|
Definition
| A bond formed when two atoms share a pair of electrons |
|
|
Term
|
Definition
| A chemical formula that shows the arrangement of atoms in a molecule or a polyatomic ion; each dash between a pair of atoms indicates a pair of shared electrons |
|
|
Term
|
Definition
| A bond angle at 109.5 degrees that results when a central atom forms four bonds directed toward the center of a regular tetrahedron |
|
|
Term
|
Definition
| A covalent bond in which three pairs of electrons are shared by two atoms |
|
|
Term
|
Definition
| A pair of valence electrons that is not shared between atoms |
|
|
Term
|
Definition
| The two weakest intermolecular attractions - dispersion interactions and dipole forces |
|
|
Term
|
Definition
| Valence-shell electron-pair repulsion theory; because electron pairs repel, molecules adjust their shapes so that valence electron pairs are as far apart as possible |
