How did Antoine Lavoisier say substances should be named?
Antoine Lavoisier proposed that substances should be named based on their elemental composition, meaning that they should be named using the elements they are composed of.
What did lavoisier contribute to the periodic table?
In 1789 Lavoisier published his Elementary Treatise of Chemistry in which he identified oxygen, nitrogen, hydrogen, phosphorus, Mercury, zinc and sulphur as substances which could not be broken down further - that is, they were identified as elements.
Did Antoine Lavoisier discover 33 elements?
No, Antoine Lavoisier did not discover 33 elements. He is known for his contributions to the field of chemistry, including establishing the law of conservation of mass and naming oxygen and hydrogen as elements. Lavoisier is credited with identifying and characterizing around 33 elements.
Why did Antoine lavoisier change the periodic table?
Antoine Lavoisier determined that oxygen was a key substance in combustion, and he gave the element its name. He developed the modern system of naming chemical substances and has been called the “father of modern chemistry” for his emphasis on careful experimentation.
Which scientist showed that the total mass of the substances in a chemical reaction is always the same before and after the chemical reaction?
Antoine Lavoisier, a French chemist, is credited with demonstrating that the total mass of substances in a chemical reaction remains constant. This fundamental principle is known as the law of conservation of mass and is a cornerstone of modern chemistry.

Who classified elements?
lavoisier.
What is the definition of a elemant according to Lavoisier?
Antoine Lavoisier defined an element as a substance that cannot be broken down into simpler substances by chemical means. He proposed the Law of Conservation of Mass and the concept of chemical elements in his work on the nature of matter.
Did Antoine Lavoisier discover 33 elements?
No, Antoine Lavoisier did not discover 33 elements. He is known for his contributions to the field of chemistry, including establishing the law of conservation of mass and naming oxygen and hydrogen as elements. Lavoisier is credited with identifying and characterizing around 33 elements.
How did lavoisier distinguish between compounds and elements?
Lavoisier distinguished between compounds and elements by conducting experiments to show that compounds can be broken down into simpler substances, while elements cannot be further broken down by chemical means. He also proposed the Law of Conservation of Mass, which states that the total mass of substances present before a chemical reaction is equal to the total mass after the reaction, providing further evidence for the distinction between compounds and elements.
Who classified elements into four categories?
Antoine Lavoisier classified elements into four categories: metals, nonmetals, earths, and gases.
What is the for the reaction that breaks substances into their basic elements?
The reaction that breaks substances into their basic elements is called a decomposition reaction. Modern chemistry is said to have started when an 18th century Frenchman, LaVoisier, heated a gray ore and got mercury and oxygen out of it! The first recognized decomposition reaction.
What are the simplest substances cannot be broken down into any other substances?
You think to atoms of chemical elements.
What is stoichiometry all about?
Stoichiometry is about the Lavoisier's principle on the conservation of mass and elements in chemical reactions.[Cf. Related links on A. Lavoisier, below this answer]

Why did lavoisiers classification fail?
Lavoisier's classification system failed because it was based on the elemental theory that all substances are composed of earth, air, fire, and water, which was later proven incorrect. Additionally, Lavoisier's system did not account for the wide variety of elements that were discovered after his time, leading to inaccuracies and limitations in classification.
