John Dalton's Atomic Model

John Dalton's Atomic Model proposed that matter is made up of small, indivisible particles called atoms. Each element consists of atoms of a specific type, which are unique in weight and size. Dalton suggested atoms are like tiny, solid spheres that cannot be broken down further. These atoms combine in fixed ratios to form compounds. His model was foundational in understanding chemical reactions, emphasizing that atoms are the basic building blocks of matter. While later refined with more complex theories, Dalton's model was crucial in establishing the concept of the atom in science.
