Antoine Lavoisier‚ deemed the father of modern chemistry‚ was born August 26‚ 1743 in Paris‚ France‚ but he did not pursue his love for science as a career until after he received a bachelor’s degree in law and obtained a license to practice law in 1764. Lavoisier always had a strong interest in the sciences‚ but was encouraged by his father to consider it only a hobby. However‚ in 1764‚ the same year he decided against practicing law‚ his first scientific paper was published‚ and he was elected

Known mainly for his works in naming elements like oxygen and hydrogen‚ establishing the infrastructure of the phlogiston theory‚ developing the metric system and helping establish the role oxygen plays in a combustion reaction he has most significantly changed Chemistry as a whole for millions around the world. Mr. Lavoisier was born on August 1743 to a noble family in Paris‚ France. At that time‚ historically

Currently‚ the atom is known as the basic unit of a chemical‚ but there was a time when that was not known among scientists. There were multiple scientists that contributed to the creation of the first Atomic Theory: Democritus‚ Antoine Lavoisier‚ Joseph Proust‚ and John Dalton. Dalton took the information that he had taken from the three scientists prior to him and put everything into one theory. The Atomic Theory is the most well-known and accurate theory we know right now. Later on in history

In the late 1700 ’s another Frenchman‚ Proust‚ discovert that elements can be combined to make different compounds‚ and that certain proportions had to be used. This became know as "law of definite proportions". A few years later an English chemist‚ John Dalton‚ a fan of Boyle worked on Proust ’s theory and came up with "the law of multiple proportions"

Antoine Lavoisier was a French nobleman that had made a hobby of chemistry. However because of this bored tax collector with a passion we were able to accurately test countless theories. Lavoisier created the “Law of Conservation of Matter‚” which stated that no matter could be created or destroyed. This Law caused a flurry of questions‚ were did this

Law of Conservation of Mass – Discovered by Antoine Laurent Lavoisier. States that matter can neither be created nor destroyed. There is no detectable change in mass in an ordinary chemical reaction. Lavoisier proved this law by conducting many experiments in which he showed that eth total mass of matter at the end of the experiment was exactly the same as that at the beginning. Law of Constant Composition – Discovered by Joseph Proust. States that any
