    Atoms are a part of everything and can't be destroyed
  • James Dalton

    James Dalton
    that the variation of vapour pressure for all liquids is equivalent, for the same variation of temperature, reckoning from vapour of any given pressure.
  • J.J. Thomson

    J.J. Thomson
    He discovered the electron
  • Hantaro Nagaoka

    Hantaro Nagaoka
    Discoverd that an atom has a central nucleus
  • Ernest Rutherford

    Ernest Rutherford
    Came up with the idea that an atom has a dece positivelty charged nucleus.discovered the arrangement of the subatomic particles in the atom.He used thin gold foil in his expermint.
  • Neils Bohr

    Neils Bohr
    a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus.he Bohr model gives almost exact results only for a system where two charged points orbit each other at speeds much less than that of light. This not only includes one-electron systems such as the hydrogen atom, singly ionized helium, doubly ionized lithium, but it includes positronium and Rydberg states of any atom where one electron is far away from everything else. It can be used for
  • James Chadwick

    neutron.
  • Werner Heisenberg & Erwin Schrodinger

    Werner Heisenberg & Erwin Schrodinger
    it shows that electrons on an orbit around the nucleus and the only way to find the location of an electron with in an atom is through the means of probability.
