When did Lavoisier make his discovery about the atom?

The first breakthrough in the study of chemical reactions resulted from the work of the French chemist Antoine Lavoisier between 1772 and 1794. Lavoisier found that mass is conserved in a chemical reaction.

What did Antoine Laurent Lavoisier discover?

Antoine Lavoisier/Discovered

Antoine-Laurent Lavoisier, a meticulous experimenter, revolutionized chemistry. He established the law of conservation of mass, determined that combustion and respiration are caused by chemical reactions with what he named “oxygen,” and helped systematize chemical nomenclature, among many other accomplishments.

What was Antoine Lavoisier first discovery?

Antoine laurent de lavoisier has first made the laws of conservation of mass. He discovered oxygen and hydrogen and disproved the phlogiston theory. People refer to him as the father of modern chmsitry. Lavoisier was a French nobleman who lived in the mid-late 18th century.

Why did John Dalton discover the atomic theory?

Dalton’s atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. Parts of the theory had to be modified based on the discovery of subatomic particles and isotopes.

How did Antoine Lavoisier contribute to the atomic model?

A later breakthrough in the discovery of the atomic model came through the work of French chemist Antoine Lavoisier who through a series of experiments found that the total mass of products and reactants in a chemical reactions is always the same. This led to the theory of the law of conservation of mass.

How did Antoine Lavoisier develop the law of Conservation of mass?

The law of conservation of mass was formulated by Antoine Lavoisier (1743-1794) as a result of his combustion experiment, in which he observed that the mass of his original substance—a glass vessel, tin, and air—was equal to the mass of the produced substance—the glass vessel, “tin calx”, and the remaining air.

Who was the first person to use the atomic theory?

Antoine Lavoisier and the Atomic Theory. Born in 1743, Antoine Lavoisier is credited as being the first person to make use of the balance.

When did Antoine Lavoisier develop his theory of combustion?

Lavoisier’s chemical research between 1772 and 1778 was largely concerned with developing his own new theory of combustion. In 1783 he read to the academy his paper entitled Réflexions sur le phlogistique (Reflections on Phlogiston), a full-scale attack on the current phlogiston theory of combustion.
