binary compound
|
Easiest compounds to write formulas for which are composed of two elements. |
|
|
chemical bond
|
The force that holds atoms together in a compound. |
|
|
chemical formula
|
Shows what elements a compound contains and the exact number of the atoms of each element in a unit of that combined. |
|
|
covalent bond
|
The attraction that forms between atoms when they share electrons. |
|
|
electron dot diagram
|
A structural formula in which electrons are represented by dots; two dots between atoms represent a covalent bond. Also known as the Lewis formula.
|
|
|
hydrate
|
A compound that has water chemically attached to its atoms and written into its chemical formula. |
|
|
ion
|
Charged particle that has either more or fewer electrons than protons. |
|
|
ionic bond
|
The force of attraction between the opposite charges of the ions in an iconic compound. |
|
|
molecule
|
The neutral particle that forms as a result of electron sharing. |
|
|
nonpolar bond
|
A covalent bond in which electrons are shared equally by both atoms. |
|
|
nonpolar molecule
|
A molecule that does not have oppositely charged ends. |
|
|
oxidation number
|
A positive or negative number that indicates how many electrons an atom has gained, lost, or shared to become stable. |
|
|
polar bond
|
A bond in which electrons are shared unequally, resulting in a slightly positive end and a slightly negative end. |
|
|
polar molecule
|
One in which the unequal sharing of electrons results in a slightly positive end and slightly negative |
|
|
polyatomic ion
|
A positively or negatively charged, covalently bonded group of atoms. |
|
|
valence electron |
An electron that is associated with an atom, and that can participate in the formation of a chemical bond. |
