3. Antoine Lavoisier
He was a chemist central to the 18th century Chemical revolution. He is considered to be the “Father Of Modern Chemistry” because of his discoveries and explanations.

4. Main Accomplishments Declined the Phlogiston theory Named oxygen
Named hydrogen
Helped create the metric system

5. Phlogiston theory
Phlogiston was a substance believed to be released during combustion and the calcination of metals. Earlier chemist thought that a metal was made up of calx and phlogiston, and that the burning happened because of the loss of phlogiston. The fact that metals actually gained weight during combustion was usually explained by the theory that phlogiston had negative weight.

6. What did Lavoisier do about it?
He saw that it was not right for something to have negative weight. So to prove it he introduced quantities measurement.
He showed that in all cases of combustion where an increase in weight happened, air was taken in, and that when a Calx was burned with charcoal, air was released.
Lavoisier's findings showed that the total weight of the substances taking part in a chemical reaction remains the same before and after the reaction which is an early statement of the law of conservation of mass.

7. Naming Oxygen and Hydrogen
Later he named the air that was released in the theory. He found out it combined with other chemicals to form acid. In Greek OXY means sharp, this refers to the sharp taste of acids. So it’s called Oxygen.
Earlier in time, Henry Cavendish discovered hydrogen but he called it inflammable air. He showed that this inflammable air burned to form a colorless liquid which is water. The Greek word for water is hydro, so he named the air that burned to form water Hydrogen.
