Discover how John Dalton's experimental methods shaped the foundation of atomic theory in modern chemistry.

570 views

John Dalton used experimental methods to propose an atomic theory in the early 19th century. Dalton’s experiments on the properties of gases and his studies on the laws of definite proportions led him to theorize that matter is composed of indivisible atoms. His contributions laid the foundation for modern chemistry, introducing key concepts such as atomic weights and symbols for elements.
