Dalton's Model
The first atomic model was created by Jhon Dalton, in these model he try to explain the composition of matter. he explain that the atom like the smalest part of an atom is indivisible, so to representate he use a simple circle, like a ball -
Period: to
Thomson Model
The whole process for the atomic model by Thompson it start when he discovered negatively charged particles through a cathode ray tube experiment. His model represents negative balls that float on a positively charged substance, simulating a cake with raisins -
Period: to
Rutherford's Model
This model is the first to add orbits to the nucleus of a positively charged atom. However the atom has a neutral charge, the electrons (in the orbits) are charged negatively and equivalent to the protons in the nucleus. -
Period: to
Bhor's Model
Like the Rutherford model, the atomic model has orbits and electrons, but the difference is that electrons jump between orbits, without going through intermediate orbits, which have a fixed value and distance to the nucleus -
Period: to
Sommerfeld's Model
Using the law of Coloumb and the relative theory of Einstain. Sommerfeld perfected Bohr's theory, explaining that the trajectory of electrons should be elliptical and not circular. Adding sub-levels to the orbits -
Period: to
Schrodinger's Model
Schrödinger's atomic model originally conceived electrons as waves of matter.
Thus, in 1916, Arnold Sommerfeld modified Bohr's atomic model, in which electrons only rotated in circular orbits, saying that they could also rotate in more complex elliptical orbits and calculated the relativistic effects. -
Period: to
Dirac Jordan's Model
in these model explain the probability of finding electrons is greater while closer to the nucleus and smaller if we move away from the nucleus, the fourth parameter with quantum characteristic, called S, appears in addition to the already known N, L and M.
It is also called "quantum model" -
Period: to
Chadwick's Model
Chadwick discover the neutron (the particle in the nucleus of the atom without electric charge)
