Atomic models

By Bread Crumbs
  • Dalton's model (By John Dalton)

    Dalton's model (By John Dalton)

    Dalton's model was a sphere which he called "atom", he believed this was the smallest particle in existence and they formed everything. He also stated that they couldn't be destroyed, created or divided.
  • Thomson's model (By Joseph John Thomson)

    Thomson's model (By Joseph John Thomson)

    Thomson's model is composed of a large sphere of positive carge with electrons (negative charge)incrusted in it and that since both had the same magnitude the atom was neutral.
  • Rutherford's model (By Ernest Rutherford)

    Rutherford's model (By Ernest Rutherford)

    Rutherford's model stated that the atom is made up of a core of positive energy and electrons orbit around it. it stays united thanks to the force of electrostatic attraction.
  • Bohr's model (By Niels Bohr)

    Bohr's model (By Niels Bohr)

    Bohr's model perfected Rutherford's model by adding that the electrons orbit around the core in determined levels and can emit or absorb energy when passing to another orbit
  • Quantum-mechanic model (By a group of scientists)

    Quantum-mechanic model (By a group of scientists)

    The latest model, explains how the electrons orbit the atom's core at spectral lines where instead of the electrons' position being determined it's based on the probability of the particle being there.
