laughed go missing, continuously, their energy and therefore collapse, approaching the atomic nucleus. Contrary to what was said above the atom should be stable, so the conclusion was that classical physics could not manage to explain the experiments, and stillneeded to be a response because the atoms emit and / or absorb certain frequencies of radiation . In September 1911, Niels Henrik David Bohr(1885-1962) starts working in the laboratory of the University of Cambridge, which was directed by JJ Thomson(1856-1940). Through this lab, Bohr Rutherford met, which led to Manchester University he worked. The mutual collaboration between these two scientists marks the history of quantum physics and arises Bohr model of the atom. Bohr, far from discarding the planetary model, sought tocorrect him on what he had more embarrassing - the strange instability atom. For this, he incorporated the Rutherford model the concept of quantum energy ...he conjectured that the electron could only move in certain orbits, which were removed at defined distances of the atomic nucleus, with no energy radiation. Thus was born the so-called "Bohr atom". So the proposed Bohr, states that each electron has specific energies, and that each of these energies corresponds to a circular orbit. The higher the energy of the electron in the atom furthest orbit is the nucleus. Bohr explains his model using the following assumptions: an electron moves in a circular orbit due to their Coulomb attraction to the nucleus; allowed only a few orbits, which are defined distances from the nucleus, not in the electron beam energy. In these orbits the angular momentum must be integers ratio of Planck's constant and 2 III. an electron moving in one of these allowed orbits does not emit electromagnetic radiation; electromagnetic radiation is emitted or absorbed if an electron moves from one orbit to another. In addition to circular orbits proposed by Bohr, Arnold Sommerfeld(1868-1951) proposes elliptical orbits, trying to explain the case of more complicated atoms.

smijali nestalo, kontinuirano, njihova energija i stoga kolaps, približava atomsku jezgru. Suprotno onome što je rekao gore atoma trebao biti stabilan, tako da je zaključak bio da je klasična fizika ne može uspjeti objasniti eksperimente, a ipakbiti odgovor jer se atomi emitiraju i / ili apsorbirati određene frekvencije zračenja . U rujnu 1911 Niels Henrik David Bohr(1885-1962) počinje raditi u laboratoriju Sveučilišta u Cambridgeu, koji je u režiji JJ Thomson(1856-1940). Kroz ovaj laboratorij, Bohr Rutherford met, što je dovelo do Manchester University radio. Međusobna suradnja između ova dva znanstvenika obilježava povijest kvantne fizike i javlja Bohr model atoma. Bohr, daleko od odbacivanjem planetarnom modelu, tražioje daga ispravi o tome što je imao više neugodno - neobičnu nestabilnost atom. Za to, on je ugrađen Rutherford modelu koncept kvantne energije ... on je pretpostavio da se elektron može samo kretati u određenim putanjama, koje su uklonjene u određenim udaljenostima od atomske jezgre, bez energetskog zračenja. Tako je rođen takozvani "Bohr atom".(ROCHA, 2002, str. 221) Tako predloženi Bohr, navodi da svaki elektron ima specifične energije, te da svaki od tih energija odgovara kružnoj orbiti. Viša energija elektrona u atoma najudaljenijeg orbiti je jezgra. Bohr je svoj model objašnjava koristeći sljedeće pretpostavke: se elektron giba u kružnoj orbiti zbog svoje privlačnosti prema Coulombovom jezgre; Dozvoljeni samo nekoliko orbita, koje su definirane udaljenosti od jezgre, a ne u elektronskim snopom energije. U tim orbitama kutni zamah mora biti cijeli omjer Planckova konstanta, a dvije III elektron se kreće u jednom od tih dopuštenih putanja ne emitira elektromagnetsko zračenje; elektromagnetsko zračenje emitira ili apsorbira Ako elektron prelazi iz jedne u drugu orbitu. Osim kružnim orbitama koje predlažu Bohr, Arnold Sommerfeld(1868-1951) predlaže eliptične orbite, pokušavajući objasniti slučaj složenije atome.
