Around 1775, Lavoisier expounded the oxidation theory of combustion with quantitative chemical experiments, which created a period of quantitative chemistry and made chemistry develop on the right track. At the beginning of the 19th century, the British chemist Dalton put forward the modern atomic theory, highlighting the atomic mass of various elements as its most basic feature. The introduction of the concept of quantity is a major difference from the ancient atomic theory. Modern atomism made the chemical knowledge and theory at that time get a reasonable explanation and become a unified theory to explain chemical phenomena. Then Italian scientist Avogadro put forward the concept of molecule. Since the atomic molecular theory was used to study chemistry, chemistry has really been established as a science. During this period, many basic laws of chemistry were established. Russian chemist Mendeleev discovered the periodic law of elements, and German chemists Libich and Weiler developed the theory of organic structure, which made chemistry a systematic science and laid a foundation for the development of modern chemistry.
