WebThe prevailing theory of atomic structure at the time of Rutherford's experiments was the "plum pudding model".This model was devised by J. J. Thomson.Thomson had discovered the electron and believed that every atom was a sphere of positive charge throughout which the electrons were distributed, a bit like raisins in a Christmas pudding.The existence of …
WebMar 28, 2024 · Rutherford’s atomic theory was that an atom had a central positive nucleus with negative electrons orbiting it. He developed this theory with his gold foil experiment. Ernest Rutherford’s gold foil experiment involved a particle emitter, a round detecting screen with a slit in it and a slip of gold foil in the middle. railway tsr boardsWebMay 8, 2024 · Proton-Neutron Hypothesis: This hypothesis was proposed by Chadwick after the discovery of neutron in 1932. A nucleus of mass number ‘A’ and atomic number ‘Z’, contains Z protons and ‘A – Z’ no. of neutrons inside the nucleus. ‘Z’ no. of electrons are revolving around the nucleus.
