  21. Dalton's 1st Atomic Theory
    Each element is compose dog extremely small particles called atoms.
  22. Dalton's 2nd Atomic Theory
    All atoms of a given element are identical, but the atoms of one element are different from the atoms of all other elements.
  23. Dalton's 3rd Atomic Theory
    Atoms of one element cannot be changed into atoms of a different element by chemical reactions; atoms are neither created nor destroyed in chemical reactions. (Law of Conservations of Mass)
  24. Dalton's 4th Atomic Theory
    Compounds are formed when atoms of more than one element combine; given compound always has the same relative number and kind of atoms. (Law of constant Composition)
  25. Law of multiple proportions
    If two elements A and B combine to form more than one compound, the masses of B that can combine with a given mass of A are in the ration of small whole numbers.
