Cards (11)

  • Provided a more precise description of the atom in Dalton's Atomic Theory

    John Dalton
  • Elements are made up of extremely small particles called atoms
  • All atoms of a certain element are exactly alike. Atoms of different elements are different
  • Atoms of same elements have the same
    sizes, mass and chemical properties
  • Atoms of one element combine with atoms of another element to form compounds
  • A chemical reaction does not result in the creation or destruction of atoms
  • A chemical reaction results only in the separation, combination, or rearrangement of atoms
  • It is the model of the atom
    Solid Sphere Model
  • Laws based on Dalton's Atomic Theory
    Law of chemical combination
  • Mass can neither be created nor destroyed in a chemical reaction
    Law of Conservation of Mass
  • A pure compound will always have the same proportion if the same elements
    Law of Constant (Definite) Proportions
