John Dalton
The contributions that he discovered is that all matter is made of atoms, absolutely everything is made of atoms. Atoms are indivisible and indestructible, Dalton thought that atoms were small particles of matter. All atoms of a given element are determined, they all have the same characteristics. Atoms of different elements vary in mass and property. -
Joseph John Thomson
Discovered the first subatomic particle, the electron J.J. Thomson discovered negatively charged particles using a cathode ray tube experiment. As a consequence of this discovery and considering that there was still no evidence of a level atom, he thought that the electrons were immersed in a positive charge. Since it has a neutral charge. Kind of like having jello with raisins floating in it. For this reason his model is known as: Raisin Pudding Model. -
Ernest Rutherford
I determine the existence of a positively charged atomic nucleus in which the highest percentage of its mass speaks. In short, his model speaks of a neutral particle. Where the patterns are in the nucleus and the electrons rotating around the nucleus so as not to collide because they are opposite charges. -
Niels Henrik David Bohr
Electrons in motion with a negative electrical charge should emit electromagnetic radiation. The model solved this problem by indicating that the electrons orbit allowed with a specific energy and with a specific energy and with a neutron in the nucleus that avoids charge shocks. It indicates that the electrons orbit around the nucleus but in certain allowed orbits with a specific energy and with a neutron in the nucleus. -
James Chadwick
he discovered one of the fundamental particles of matter, the neutron, a discovery that led directly to nuclear fission and the atomic bomb. -
Erwin Schrödinger
Study of the wave properties of matter and an equation that accurately gave the energy levels of atoms. "With the help of so-called wave mechanics you have found the solution to several problems in atomic physics.
