Chemistry was established by Lavoisier proving that the simple bodies were made of elements or produced by elements as in fire. Electron transition produces both heat and light. In 1787, Lavoisier published "Methods of Chemical Nomenclature," which included the rules for naming chemical compounds that are still in use today. His "Elementary Treatise of Chemistry" (1789) was the first modern chemistry textbook. Chemistry as a division of the sciences was established based on the first modern chemistry
