Antoine Lavoisier’s combustion theory was pivotal to the development of modern chemistry because it replaced the flawed phlogiston theory with an experimentally grounded framework based on the conservation of mass.21
While previous theories struggled to explain why substances gained weight during combustion, Lavoisier demonstrated that this process involved the chemical combination of a substance with oxygen. His work was transformative for several reasons:21
- Emphasis on Quantification: Lavoisier insisted on precise measurements, elevating chemistry to a rigorous science by proving that the total amount of matter remains constant during chemical reactions.21
- Modern Nomenclature: To support his new system, he helped develop a standardized method of chemical nomenclature in 1787, which remains the foundation for naming substances today.2
- Redefining Elements: He clarified the concept of an element as a substance that cannot be broken down, providing a logical basis for organizing chemical knowledge.1
By publishing his Elementary Treatise on Chemistry, Lavoisier established the systematic methods and rational principles that define modern chemical investigation.2
