Abstract
Precise definitions are given of basic chemical concepts (matter, material; solid, liquid, gas, vapour; mixture, substance, solution, solvent, solute; physical, physicochemical, chemical, radiochemical; element, compound, allotropy, stoicheiometric, nonstoicheiometric). These definitions are formulated entirely at a macroscopic level, and are suitable for presentation to beginners. [Chem. Educ. Res. Pract.: 2003, 4, 19-24]
