Web13 de mar. de 2016 · Niels Bohr which after his PhD circa 1912 had joined Rutherford realized that Rutherford's model wasn't quite right and started to articulate a model that borrowed from Planck's quantum theory. This approach allowed Niels to explain a relatively stable atomic Model, which still hinged on the orbital model that Rutherford postulated. WebHow did Bohr discover his atom model? It was while Bohr was working in England in 1913 that he developed this atomic model. He developed the model after studying the way glowing, hot hydrogen gives off light.
