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 WebWhich statements are inconsistent with Rutherford’s nuclear theory as it was originally stated? Why? a. Since electrons are smaller than protons, and since a hydrogen atom contains only one proton and one electron, it must follow that the volume of a hydrogen atom is mostly due to the proton. b. A nitrogen atom has 7 protons in its nucleus and 7 … WebRutherford's experiment with alpha particle scattering by gold foil established that: A. electrons have a negative charge. B. protons are 1840 times heavier than electrons. C. protons are not evenly distributed throughout an atom. D. atoms are made of protons, neutrons and electrons.
