John Dalton Tanpreet and Manvir
Personal Story • Born September 6, 1766 – died July 27, 1844 • Gave lectures on natural philosophy at the age of 12 • Made principal within 4 years • His brother and him were born color blind • This led him to research color-blindness, which is officially known as Daltonism
Idea of the Atom 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
Experiments/ Areas of Study • 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
Major Scientific Contribution • 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.
