Werner Heisenberg went to University or Munich to study physics. Schrödinger was a student at University of Vienna from 1906 to 1910. He acquired a mastery of eignenvalue problems in the physics continues media. In the 1930's they discovered the Electron Cloud. They modified Rutherford model by proposing that the orbital of electrons is restricted to predefined orbits and they can make a transition between the orbits on absorbing or emitting energy. It was kind of similar to the Bohr Model but the electrons was totally different like the electron look like little particles floating around the nucleus but the Bohr electron look like its orbiting around the nucleus. The only problem with the Electron cloud was that we didn’t know where the electrons are. Now if you look at the Electron cloud it look like the proton and neutron are form into little particles and the electrons look like little particles floating around the nucleus.

Ernest Rutherford went University of New Zealand, in 1889, where he was awarded a scholarship. Then he enter into Canterbury College, where he graduated M.A., in 1893 with a double in first mathematic and physic science. He continue with research work at college for a short time, recieving his B.Cs. degree. In 1909 Ernest Rutherford discovered the Planetary Model, which was another name for the Rutherford model, he developed this model of atom with the protons in the nucleus and the electron orbting around the nucleus, like a sun orbiting around earth. When he did test on this, what he did was a stream of alpha particles was directed at a thin foil of gold atoms and dector arranged to surround the same completely, except for a small for a entry of the particles. In his beforehand model the electron had took up a lot of space but now it depends on the size of the atom. There was number of different problems with the model because when the energy of the electron would slow down it would eventually would collaspe, but rutherford couldnt explain why it collaspe. Now the model is the electron and neutron form into a particle while the electron is orbiting around them.

J.J Thompson enrolled at owens college manchester in 1870. Then in 1876 he entered trinity college as a minor scholar.the thompson model was discovered in Great Britian in 1904.There were many experiments used leading up to the thompson model. The Investigations In the Thompson model, stated the ideas in the model could be separated by using magnetism another investigation stated whether or not the rays could be deflected by an electron field. In the last experiment thompson measured the mass-to-charge ratio of the cathode raysTthe atom is composed and surrounded by a soup of positive charge to balance the electron's negative charge. Thomson was not successful in making his model account for some major spectral lines known for some elements. He had negative electron scatter everywhere.

Neils Bohr Went to Copenhagen University he also recieved his masters degree in physics in 1909 and his doctor's degree in 1911.The model was created in 1885 along with adding in quatuum theory. The electrons orbiting around the nucleus according to Newton's laws would sooner or later lose energy and eventually fall into the nucleus. The electrons are put on seperate fixed energy levels. Everything is cordniated together.the electrons are on the outside they are like an resemble an orbiting planet.
John Dalton Discovered the Daltons model in September of 1803. Before this model was discovered John Dalton he began teaching in his native town at the age of 12. Dalton, his older brother, and cousin conducted a school in Kendal. In 1798 he went to manchester and spent the rest of his life teaching at a new college and then later became a private tutor.He was a long Bachelor and died july 1844. He also incorporated the Atomic theory. The discovery of Daltons model was lead by the discovery that in reaction, volumes of gases always reacted in whole number ratios. An example of this would be that when you decomposed water you always got twice the volume of hydrogen compared to the volume of oxygen. This was the fist and last Daltons model. Daltons model doesnt have any electrons, neutrons. or protons. The only problem he had making this model he had was that atomic weight of oxygen that was assigned was seven.
