Michael Faraday

Michael Faraday, oil on canvas by Thomas Phillips, 1841–42; in the National Portrait Gallery, London.
Faraday, who became one of the greatest scientist of the 19th century, began his career as a chemist. He wrote a manual of practical chemistry that reveals his mastery of the technical aspects of his art, discovered a number of new organic compounds, among them benzene, and was the first to liquefy a “permanent” gas.

Bohr Atomic model

Imagen
Bohr agreed with Rutherford’s proposal that in the atom the electrons revolve around a central positively charged nucleus that is responsible for most of the weight of the atom. But from his special evidence, he concluded that electrons are found at only certain distances from the nucleus, and have particular values of energy. ohr’s atomic theory also helped to explain the spectra. He explained the discrete lines on the hydrogen spectra by proposing if a hydrogen atom was given energy, an electron can jump to a higher shell, away from the nucleus. However they will always return back to their ground state as the atom will be unstable.

Jhon Dalton Atomic model

proposed that elements consisted of atoms that were identical and had the same mass and that compounds were atoms from different elements combined together, his atomic model was a simple sphere. He also stated that atoms of a given element are idntical in size, mass, and other properties.As democriyus he also thought that atoms cannot be subdivided, created, or detroyed.

J.J Thomson Atomic model

From this he discovered that no matter what metal the electrodes were made up of or what type of gas was in the tube, the mass to charge ratio was unchanged. He also deducted that there were two parts of atom held together by electrostatic attraction. A heavier part, responsible for the majority of mass of the atom and a negatively charged ‘corpuscle’. This meant that Dalton’s model of an atom was incorrect, since the atom was not the smallest possible particle.
