3. Atomic Theory Matter is composed of small particles called atoms, cannot be broken into smaller particles, created or destroyed Atoms of any given element are all identical to each other and different form the atoms of other elements Atoms of different elements combine in specific ratios to form compounds In a chemical reaction, atoms are separated, rearranged, and recombined to form new compounds Idea of the Atom

4. Studied weather, atmospheric pressure and meteorology Daltons Law of Partial Pressures Discovery of air and its components Performed numerous experiments of mixtures of gases Daltonism Experiments/ Areas of Study

5. Atomic Theory All matter is composed of extremely small particles called atoms, which cannot be broken into smaller particles, created, or destroyed. The atoms of any given element are identical to each other and different from the atoms of other elements. Atoms of different elements combine in specific ratios to form compounds. In a chemical reaction, atoms are separated, rearranged, and recombined to form new compounds. Major Scientific Contribution
