Antoine Lavoisier, a shining star in Chemical world

There is no denying the fact that Antoine Lavoisier was the greatest scientist and had contributed a lot for the welfare of mankind. As a  scientist he had enriched lots of inventions in the shining star of Chemistry and by dint of his merit and hardihood, he firstly proclaimed that while breathing we take oxygen  and leave carbon dioxide in case of breathing out by surviving spontaneously on earth. So far our knowledge goes, he spent his life by carrying out research work on chemistry as a chemist. His life sketches were given below briefly.
  • Occupation: Chemist
  • Born: August 26, 1743 in Paris, France
  • Died: May 8, 1794 in Paris, France
  • Best known for: Founder of modern chemistry
Biography:
Early Life

As per history of the Chemist world, Antoine Lavoisier was born in Paris, France on August 26, 1743 he  grew up in a civilized, aristocratic and wealthy family. His father was a lawyer and his mother died when he was only five years old. That is to say, at a very early age, he was deprived of motherly affection and it was a clear indication that he would struggle for existence on earth. In real life situation he had to live by working hard with painstaking souvenir.

Antoine discovered his love for science while attending college. However, he initially was going to follow in his father's footsteps, earning a law degree.

Career

Lavoisier never did practicing law as he found science much more interesting and enthusiastic. He had inherited a good deal of money when his mother died and was able to live as a nobleman, pursuing various interests. Lavoisier worked in various government positions and was elected to the Royal Academy of Science in 1764.

In 1775, Lavoisier set up a research center  in Paris where he could run experiments. His lab became a gathering place of scientists. It was in this lab where Lavoisier made many of his important discoveries in schools of chemistry. Lavoisier considered it important to use experiments, precise measurements, and facts in science.

The Law of Conservation of Mass

One of the main scientific theories of Lavoisier's time was the phlogiston theory. This theory stated that fire, or combustion, was made up of an element called phlogiston. Scientists thought that when things burned they released phlogiston into the air.

Lavoisier disproved the phlogiston theory. He demonstrated that there was an element called oxygen that played a major role in combustion. He also showed that the mass of products in a reaction are equal to the mass of the reactants. In other words, no mass is lost in a chemical reaction. This became known as the Law of Conservation of Mass and is one of the most important and basic laws of modern chemistry and physics.

The Elements and Chemical Nomenclature

Lavoisier spent a lot of time isolating elements and breaking down chemical compounds. He invented a system of naming chemical compounds that were made up of multiple elements. Much of his system is still in use today. He also named the element hydrogen.

Water is a Compound

During his experiments, Lavoisier discovered that water was a compound made of hydrogen and oxygen. Prior to his discovery, scientists throughout history had thought that water was an element.

The First Chemistry Textbook

In 1789, Lavoisier wrote the Elementary Treatise of Chemistry. This was the first chemistry textbook. The book contained a list of elements, the most recent theories and laws of chemistry (including the Conservation of Mass), and refuted the existence of phlogiston.

Death

The French Revolution began in 1789. Lavoisier attempted to remain separate from the revolution, but because he had worked as a tax collector for the government, he was branded a traitor. On May 8, 1794 he was executed by guillotine. A year and a half after he was killed, the government said he had been falsely accused.

Interesting Facts about Antoine Lavoisier
  • His wife, Marie, played an important role in his research helping to translate English documents to French so he could study them. She also drew illustrations for his scientific papers.
  • Lavoisier did experiments with breathing and showed that we breathe in oxygen and breathe out carbon dioxide.
  • He worked as commissioner of the French Gunpowder Commission for many years.
  • One of the elements listed in his textbook was "light."
  • He demonstrated that sulfur was an element rather than a compound.
