| A | B |
| binary compound | A compound consisting of two elements. |
| bond angles | The angle between two bonds that share a common atom. |
| covalent bond | The attractive force holding two atoms together resulting from the sharing of a pair of electrons. |
| dipole moment | A measure of the size of a dipole. |
| double bond | The shared double bond provides an octet around each carbon atom. |
| electronegativity | The ability of an atom covalently bonded to another atom to draw the bonding electrons toward itself. |
| nonbonded electrons | Pairs of electrons not shared in a covalent bond. |
| ionic bond | A strong electrostatic attraction between a positive ion and a negative ion; results when electrons are transferred from the valence shell of one atom into the valence shell of another. |
| molecular formula | The formula that shows the numbers of the atoms of the elements |
| Stock system | Modern method of nomenclature of ions with more than one charge type. |
| valence-shell electron-pair repulsion (VSEPR) theory | A theory that accounts for the symmetrical distribution of atoms around a central atom in a covalent compound. |
