used to keep track of electrons during bonding. (A number that reflects the charge that an atom in a compound would have if all the bonding electrons are arbitrarily assigned to the most electronegative element.
a class of compounds in which two oxygens are bonded together. (A compound that contains an oxygen-oxygen bond)
System of names that allows all compounds to be named according to a common set of rules. (A system or set of names used by a branch of learning, such as the system of names for compounds in chemistry.)

Greek prefix system
A system of prefixes used to indicate the number of atoms in a binary covalent compound or the number of water molecules in a hydrate. (Example: Dinitrogen Pentoxide)
A compound that contains only two kinds of elements. (ionic and named according to each of the two ions that are involved.)
An anion composed of oxygen and one other element.
A compound that contains at least three different elements & do not use prefixes. (Example: NaNO)
A convention used to show the oxidation state of a metal ion in which a roman number is placed after the elements name to show the oxidation number. (Example: CuCl(lil 2) is Copper (II) Chloride.)
