Bohr's atomic model
of Rutherford's experiments. And the discovery of the neutron Zack Vick. Revealed that protons and neutrons together in atomic nuclei. I still do not know what sort of electrons in the structure of the atom. Need to know that electrons surrounding the nucleus in any manner. Scientists have studied the flames from the burning of various substances and educational spectrum with a tool called a spectroscope The results obtained from chemical burns. Scientists have been trying to bring the old model to explain the experimental results but can not explain it. Make assumptions about the atomic model is new. To atoms with atomic structures that can transfer energy protons. And neutrons together in the nucleus And electrons around the nucleus. Electrons rushing around the nucleus with the electron energy levels than one that runs around the nucleus moves in any energy. Based on the energy of the electron spectrum of knowledge. It Nils Bohr, a Danish scientist. Has proposed a new atomic model. The expansion follows the model of Rutherford. Atoms consist of protons and neutrons together in the nucleus. The electrons in orbit around the nucleus of a circle with a radius r, a layer or a power level that is only one power similar to the orbits of the planets around the sun. He called the orbits of electrons near the nucleus. And that the class K has the lowest energy orbit to the next and called out. The energy level picks up, the class L, M, N, O ..., respectively, but the current run-class K, L, M, ... that the energy levels n = 1, n = 2, n = 3, respectively.
