The Laws of Chemical Combination: Indirect Evidence for the Existence of Atoms The existence of elements as fundamental substances does not per se provide any indication concerned with the nanoscopic structure of matter. The first evidence for atoms was obtained by analyzing the respective weights of products and reactants which led to two laws: Law of conservation of mass (Lavoisier): Mass is neither created nor destroyed during a chemical reaction. Example: 4.0 g of hydrogen + 32.0 g of oxygen = 36.0 g of water
