  50. Theory: Atomos (Atom)= uncuttable, indivisible
    Democritus of Abdera
  51. Theory:
    1. First to associate the ancient idea of atoms with stoichiometry
    2. That a given compound always contains the same proportions (by mass) of the element
    3. *Law of Constant Composition*
    John Dalton
  52. Theory:
    1. Atom is breakable
    2. Cathode rars are negatively charged particles
    3. Particles are constituents of the atom
    4. Atom's structure has electrons suspended in a positively charged electric field
    J. J. Thomson
  53. Theory:
    1. Atom mostly empty space
    2. Atom contains a dense particle that was small in volume, compated to the atom, but large in mass
    3. This dense particle was positively charged
    Rutherford
  54. Dalton's Atomic Theory
    • 1. Elements are made of tiny particles called atoms.
    • 2. Atoms of one element can combine with atoms of other elements to form compounds
    • 3. Atoms are indivisible in chemical processes.
