    Journey of the Atom

  • Dec 15, 1574

    Giordano Bruno

    He thought that god existed in atoms.
  • Isaac Newton

    He thought that atoms can move and are not stationary.
  • John Dalton

    John Dalton proposed that atoms have always existed and cannot be created or destroyed, everything is made from atoms, they are the smallest and cannot be broken apart, chemical reactions occur when atoms move and that atoms of the same element are alike because they have the same mass. He also had many more contributions
  • Henri Becquerel

    He founded radioactivity when he researched uranium and other subtances that were radioactive.
  • J.J Thompson

    He discovered the electron and made the plum-pudding model of the atom.
  • Robert Milikan

    He found out about the electric charge of electrons.
  • Henry Moseley

    He worked on many theories about the atomis number. He also organised many elements on the periodic table.
  • Ernest Rutherford

    His Geiger–Marsden experiment gave us information about the atomic structure, where the atom is a nucleus and electrons orbit around it.
  • Neils Bohr

    Neils Bohr discovered the revised structure of the atom.
  • Louis de Broglie

    He discovered that electrons are similar to both particals and waves. He also supported Einstein.
  • Erwin Schrodinger

    He came up with the schrodinger theory.
  • Werner Heisenberg

    He discovered the Heisenberg Uncertainty Principle.
  • James Chadwick

    He discovered the neutrally-charged neutron.
