Dalton
Dalton's atomic model emerged in the context of chemistry, was the first atomic model with scientific bases, formulated between 1803 and 1807 by John Dalton. -
Thomson
Thomson's atomic model is a theory about the atomic structure proposed in 1904 by Joseph John Thomson, who discovered the electron in 1898, long before the discovery of the proton and the neutron. -
Rutherford
Rutherford's model was the first atomic model that considered the atom formed by two parts: the "crust", constituted by all its electrons, rotating at high speed around a very small "nucleus"; which concentrates all the positive electrical charge and almost all the mass of the atom. -
Bohr
Bohr's atomic model is a classic model of the atom, but it was the first atomic model in which a quantization to be introduced from certain postulators is introduced. It was proposed in 1913 by the Danish physicist Niels Bohr, to explain how electrons can have stable orbits around the nucleus and why the atoms presented characteristic emission spectra (two problems that were ignored in Rutherford's previous model). -
Sommerfeld
In 1916, Sommerfeld perfected Bohr's atomic model trying to alleviate the two main defects of it. For that sop ofnponu basic modifications: Almost-elliptical orbits for electrons and relativistic velocities. -
Schodïnger
The atomic model of Schrödinger (1924 is a non-relativistic quantum model. It is based on the solution of the Schrodinger equation for an electrostatic potential with spherical symmetry, also called hydrogen atom. In this model the electrons were originally regarded as a standing wave of matter whose amplitude decayed rapidly when exceeding the atomic radius.
