Antoine-Laurent de Lavoisier (lə-VWAH-zee-ay;[1][2][3]French:[ɑ̃twanlɔʁɑ̃dəlavwazje]; 26 August 1743 – 8 May 1794),[4] also Antoine Lavoisier after the French Revolution, was a French nobleman and chemist who was central to the 18th-century chemical revolution and who had a large influence on both the history of chemistry and the history of biology.[5]
It is generally accepted that Lavoisier's great accomplishments in chemistry stem largely from his changing the science from a qualitative to a quantitative one. Lavoisier is most noted for his discovery of the role oxygen plays in combustion. He named oxygen (1778), recognizing it as an element, and also recognized hydrogen as an element (1783), opposing the phlogiston theory. Lavoisier helped construct the metric system, wrote the first extensive list of elements, and helped to reform chemical nomenclature. He predi

A priori components of science: Lavoisier and the law of conservation of mass in chemical reactions
A PRIORI COMPONENTS OF SCIENCE: LAVOISIER AND THE LAW OF CONSERVATION OF MASS IN CHEMICAL REACTIONS Roberto de Andrade Martins Abstract: In his book “Identité et réalité”, Émile Meyerson argued for a philosophical a priori background in the case of all scientific conservation laws. This work discusses one of the specific cases he addressed, the conservation of mass in chemical reactions. It analyzes the attitudes of Antoine Laurent de Lavoisier and Hans Landolt regarding their own experiments concerning this law of conservation. This case study is relevant for the teaching of chemistry (and of science, in general), because it clearly shows the influence of philosophical principles on the development of science, thereby providing a nice example against the inductivist view of science. Keywords: mass conservation; a priori laws; history of chemistry; philosophy of chemistry; philosophy of science; Lavoisier, Antoine-Laurent; Landolt, Hans; Meyerson, Émile 1.

Scientists that contributed to the Atomic theory
- Democritus was an Ancient Greek philosopher born in Abdera, Thrace, Greece. He thought hard about matter and the universe and thought of an atomic theory. In 5th century BCE, Democritus stated that all matter was made up of tiny units that moved around. He believed that these units are invisible and unchangeable. He decided to call these tiny units atomos, which in Greek, means uncuttble.
- During the 6th centuary BCE, a man named kanada, who founded the aishesika school of philosophical came up on his own atomic theory. His idea was that matter was made on a finite number of paramaṇus (atoms) which were indivisible and eternal. Atoms make up the 4 elements water, fire, earth and air, which make up matter. They believed that the interactions between these atoms, causing them to combine was caused by the will of shvara, a Hindu god
- Antoine Lavoisier was born on 26th of august 1743. Lavoisier named oxygen in 1778, hydrogen in 1783 and predicted silicon in 1787. He put together the very first list of
