Apr 27, 2014· Rutherford's experiment showed that the atom does not contain a uniform distribution of charge. > Thomson's plum pudding model viewed the atom as a massive blob of positive charge dotted with negative charges. A plum pudding was a Christmas cake studded with raisins ("plums"). So think of the model as a spherical Christmas cake. When Rutherford shot α particles through gold foil, he .

Rutherford backscattering spectrometry - Wikipedia

Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science.Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.

Design a test to determine whether thorium-234 also emits particles. First, explain how Rutherford's experiment measured positive particles aimed at the gold foil. Then, explain a test that might detect whether particles are emitted from thorium-234. Last, explain why it would be more difficult to detect the release of neutrons than protons.
