    Democritus

    Revolves around the atoms that are present in the atmosphere. These are about the atoms that are present in all the forms of existence.
  • John Dalton

    John Dalton

    Dalton concluded that evaporated water exists in air as an independent gas.
  • Ernest Rutherford

    Ernest Rutherford

    Conducted some experiments to search the problem of alpha particles scattering by the thin gold-leaf. Rutheford knew that the particles contain the 2e charge.

    J.J. Thompson

    Thomson interpreted the deflection of the rays by electrically charged plates and magnets.

    electrons revolving around the nucleus, bound by electrostatic forces (in analogy to the rings revolving around Saturn, bound by gravitational forces).That is why he called his model the SaturnianModel
  • Niels Bohr

    Niels Bohr

    He discovered that electrons traveled in orbits around the atom's nucleus that the chemical properties of the element was largely determined by the number of electrons in the outer orbits that an electron could drop from a higher-energy orbit to a lower one, emitting a photon (light quantum) of discrete energy.

    Werner Heisenberg & Erwin Schrodinger

    The electron cloud model shows the probable locations of electron in an atom. The probability of finfing a n electron is higher in the denser regions of the cloud.
  • James Chadwick

    James Chadwick

    He proved neutrons. He concluded in his experiment that the particles produced were neutral because a charged object id not deflect their paths.
