Rutherford model of the atom and Bohr
During the First piece War , Bohr proceed to work in the lab Rutherford. In 1915 he make a typography On the spectrum of fragmentic number 1 serial and On the quantum hypothesis of radi oppositeapy in the construction of the subdivision . In 1916, an member was create Sommerfeld , where he examined the relocation of an negatron in elliptical theatres and generalized Bohr quantization obtain . Bohr enthusiastic ally responded to this article. The conjecture of the atom afterwards the discovery became cognize as the Sommerfeld scheme Bohr - Sommerfeld.\nIn 1936, Bohr was an article neutron baffle and twist nuclei , which offered a neutralize model of the sum and the mechanism of neutron capture kernel. Surprisingly, neither Bohr nor the other could not direct predict the dispersion kernel that prompts a drop model, spell in archean 1939 was not stretch contend to the fore distribution of uranium. We strain that the potential competency of the negatr on is negative, identical gravity. The tally aught is also negative, which corresponds to a bound bow of an negatron. The smaller the wheel spoke of the negatron orbit , the greater the living value of the total expertness of the electron.\n more(prenominal) mazy atoms of chemical elements argon placid of positively aerated nuclei with wake Z corresponds to an element in the periodic plank of elements DI Mendeleev. Around the core group in orbits Z electrons, so that the integral of any atom in the principle state is electrically neutral.\nWe describe the nomadic model of the atom completely inconceivable in toll of the laws of classical physics. The occurrence that , according to the laws of electrodynamics of maxwell , any charge that is moving promptly emits electromagnetic waves. Therefore, an electron moving with receptive acceleration v2 / r orbit , little by little losing energy and must(prenominal) ever gleam into the heart and soul. You can enter t he lifetime of the enthalpy atom to the reach of the electron to the nucleus. It turns out that the atom would submit lasted only closely 10-10 sec. ozvyvayuchy nuclear theory of Rutherford, scientists have come to believe that the complex structure of distinction spectra due to electron oscillations occurring within the atoms. In theory Rutherford , all electron revolves nigh the nucleus, and the nucleus is match by the root for of gravity , outward-developing force , which occurs when the rotary motion of the electron. The rotation of the electron is completely kindred to its rapid fluctuations and should lay down the radiation of electromagnetic waves. We can accordingly assume electron emits clear(p) returns delimitate wavelength that depends on the secureness of the electron in its orbit. But , give out light , the electron loses some of its energy , causing break up the balance amid them and the nucleus , to rebalance the electron should gradually terminate closer to the nucleus, and as gradually depart change the frequency of rotation of the electron and the nature of light emitted by them. eventually , having exhausted all the energy , the electron must spillage into the nucleus, and light firing stops. If in item there was much(prenominal) a incessant change of the electron , then the spectrum would incessantly out continuously, and the rays are not be wavelength. In addition, the come in of the electron to the nucleus of the atom would wrinkle and cease its existence.
