Dalton's Atomic Theory

Dalton's Atomic Theory, proposed in the early 19th century, states that matter is made up of small, indivisible particles called atoms. Each element consists of atoms of a specific type with unique weights. Atoms of different elements have different properties and combine in fixed ratios to form compounds. In chemical reactions, atoms are neither created nor destroyed but simply rearranged. This theory helped explain how substances interact and laid the foundation for modern chemistry, emphasizing that atoms are the fundamental building blocks of all matter.
