WebRutherford was gradually turning his attention much more to the α (alpha), β (beta), and γ (gamma) rays themselves and to what they might reveal about the atom. That is, he was leaving radio-chemistry to others and turning to physics. Rutherford always gathered a group of bright young researchers around him. WebHe stated that the components of chemical compounds always combine in the same proportions by weight. For example, Proust found that no matter where he obtained his …
WebRutherford’s basic model by proposing that electrons had set energy levels (Fig. 7). This is the model of the atom most commonly portrayed in textbooks: a nucleus orbited by electrons at different levels. It helped solve the problem of the collapsing atom and earned Bohr a Nobel Prize. Just as Bohr built on Rutherford’s model, many other
