Molecule: The smallest identifiable unit that retains the physical and chemical  properties of the pure substances

•COMPOUND is a combination of 2 or more elements in definite ratios by mass. 

•The character of each element is lost when forming a compound (e.g., think of NaCl).

•MOLECULES are the smallest units of a compound that retains the characteristics of the compound.
