  1. Wiki says about Dalton:

    The main points of Dalton's atomic theory were:

    Elements are made of extremely small particles called atoms.
    Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties.
    Atoms cannot be subdivided, created, or destroyed.
    Atoms of different elements combine in simple whole-number ratios to form chemical compounds.
    In chemical reactions, atoms are combined, separated, or rearranged.

  4. whoops, I saw the p but not the px
    Only 2 electrons can fit in the p orbital pointing in the x direction. You can also have 2 py electrons and 2 pz electrons.
