Antoine Lavoisier and the Origin of Modern Chemistry | AMS OpenMind


Summary

Aristotle's ancient theory on matter comprising fire, water, air, and earth endured for 2,000 years until challenged by Lavoisier's studies on combustion. Lavoisier's experiments, which included observations on phosphorus and hydrogen in water, revolutionized the understanding of matter. His discoveries contributed to the identification of 55 elements in chemistry and the foundational concept that matter cannot be created or destroyed, shaping the course of chemical history.


Ancient Greek Concept of Matter

Aristotle's theory on matter being composed of fire, water, air, and earth was accepted for 2,000 years in ancient Greece.

Lavoisier's Studies on Combustion

Lavoisier studied combustion to improve gunpowder, challenging the ancient belief of a fire-like fluid releasing flitterstone when burning.

Experiments on Phosphorus

Lavoisier conducted experiments with phosphorus in a sealed vessel, observing changes in matter before and after combustion to challenge existing theories.

Discovery of Elements

Lavoisier's experiments led to the discovery of hydrogen as an element in water, contributing to the identification of 55 elements in chemistry.

Evolution of Understanding Matter

The concept of matter evolved through scientific discoveries, leading to the understanding that matter cannot be created or destroyed, shaping the history of chemistry.
