Elements, compounds, and mixtures - Purdue University

Long before chemists knew the formulas for chemical compounds, they developed a system of nomenclature that gave each compound a unique name. Today we often use chemical formulas, such as NaCl, C 12 H 22 O 11, and Co(NH 3) 6 (ClO 4) 3, to describe chemical compounds. But we still need unique names that unambiguously identify each compound.
