Binary compund |
compound that is composed of two elements |
|
Chemical bond |
force that holds atoms together in a compound |
|
chemical formula |
chemical shorthand that uses symbols to tell what elements are in a compound and their ratios
|
|
covalent bond |
attraction formed between atoms when they share electrons |
|
electron dot diagram |
uses the symbol for an element and dots representing the number of electrons in the element's outer energy level |

hydrate |
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 ionic compund |
|
molecule |
a neutral particle that forms as a result of electron sharing among atoms |
|
nonpolar bond |
a covalent bond in which electrons are shared equally by both atoms |
|
nonpolar molecule |
molecule that shares electrons equally and does not have oppositely charged ends. |
|
oxidation number |
positive or negative number that indicates how many electrons an atom has gained, lost, or shared to become stable |
|
polar bond |
a covalent bond in which the electrons are not shared equally, resulting in a slightly positive end and slightly negative end |
|
polar molecule |
a neutral molecule in which unequal electron sharing results in a slightly positive end and a sightly negative end |
