His work in the 1820s confirmed that compounds existed in fixed proportions, bolstering the atomic hypothesis. While the ancient Greeks speculated on indivisible units, the modern scientific concept began with John Dalton in the early 19th century.
Atomic Theory Clarification: Physical States and Key Reactions Explained
The question of who first proposed atomic theory touches on the foundational shift from philosophical speculation to scientific explanation regarding the nature of matter. The existence of atoms remained theoretical until the turn of the 20th century.
By assigning atomic weights to elements, he gave chemists a powerful predictive tool, transforming chemistry from a descriptive science into a quantitative one. This finding led to the "plum pudding" model, which was later replaced by Ernest Rutherford's nuclear model.

Jöns Jacob Berzelius, a Swedish chemist, refined the theory by developing a system of chemical notation and identifying the law of constant composition. Later Validation and the Modern Atom While Dalton ignited the field, his specific model required corrections.
