  • James Dalton born

    In England
  • Dalton creates atomic theory

    Dalton’s Atomic Theory:1) All matter is made of atoms. Atoms are indivisible and indestructible.2) All atoms of a given element are identical in mass and properties3) Compounds are formed by a combination of two or more different kinds of atoms.4) A chemical reaction is a rearrangement of atoms
  • John Dalton Law of multiple porportions

    The Law of Multiple Proportions states that if two elements form 2 compounds, the mass ratio of the elements in one compound is related to the mass ratio in the other by a small whole number.
  • Dalton's law of definite composition

    The law of definite composition states: A pure compound always contains the same elements in the same proportions by mass.
