Antoine Lavoisier: Anoine Lavoiser discovered some of things that enabled the discoveries of the extensive knowledge of chemistry we have today. Without him, we would know almost nothing of all the chemicals swe know of now, we wouldn't know the atomic number, or the mass, and therefore would not be able to do much of what we do now with science. He discovered elements such as oxygen, and he discovered properties of chemicals and how to measure them. Two great scientists he influenced were Joseph Proust and John Dalton. Using the chemicals and rules that Lavoisier discovered, the uncovered much more about chemicals and atoms. Such as the weight of certain atoms, and the comisiton of certain compounds. Antoine Lavoisier was a French chemist in the 18th-century Chemical Revolution and a large influence on chemistry. He is considered to be the "Father of Modern Chemistry." Lavoisier's great accomplishments in chemistry are mainly the fact that he changed the science from a qualitative to a quantitative one. Lavoisier is widely known for his discovery of the role oxygen plays in combustion, and he recognized and named oxygen and hydrogen. Lavoisier helped construct the metric system, wrote the first extensive list of elements, and helped to reform chemical…show more content… Berthollet with the law of definite proportions, which is sometimes also known as Proust's Law. Proust studied copper carbonate, the two tin oxides, and the two iron sulfides to prove this law. He made artificial copper carbonate and compared it to natural copper carbonate. With this he showed that each had the same proportion of weights between the three elements involved. Between the two types of the other compounds, Proust showed that no neutral compounds exist between them. Without Antoine Lavoiseir's dicovery that matter can change shape, and the mass still stays the same, Proust wouldn't have been able to proove his theory by measuring the
