common name non-systematic, usesd for naming compounds, not recognized as formal nomenclature; aka trivial
type 1 binary compound binary compound in which the cation has only one form, or charge
type 2 binary compound binary compounds in which the cation can have multiple forms
systematic name name given systematically to compounds. for example: lead(IV)oxide
type 3 binary compound binary compound with two metals
polyatomic ion a charged species ion composed of two or more atoms covalently bonded or of a metal complex that can be considered as acting as a single unit in the context of acid and base chemistry or in the formation of salts
oxyanion chemical compound with the generic formula AxOyz− (where A represents a chemical element and O represents an oxygen atom)
acid substance which reacts with a base and has a pH of less than 7
ion atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge
cation ion with fewer electrons than protons, giving it a positive charge
