  • Pure SubstancesElementcomposed of identical atomsEX: copper wire, aluminum foil

  • Pure SubstancesCompoundcomposed of 2 or more elements in a fixed ratioproperties differ from those of individual elementsEX: table salt (NaCl)

  • Pure SubstancesLaw of Definite CompositionA given compound always contains the same, fixed ratio of elements.Law of Multiple ProportionsElements can combine in different ratios to form different compounds.

  • Pure SubstancesFor exampleTwo different compounds, each has a definite composition.
