Which particle was discovered in the gold foil experiment?
The Rutherford gold foil experiment is also known as the Geiger-Marsden experiments. In them, alpha particle scattering was measured, and showed how a large focus was found in such a way as to describe atoms having a dense nucleus. This experiment is not used for much today in any field other than focused particle physics, wherein it is the basis of most other calculations involving how atoms work.
E. Rutherford, H. Geiger and E. Marsden discovered that all atoms have a positive charged nucleus. The electrons orbits this nucleus. Rutherford's experiment established what an atom looks like. When Rutherford sent alpha particles toward the gold foil, some passed while others bounced back. He collected the data and made a model of the atom. The only reason why some rays went through while others bounced back because of the composition of the atom in…
If a particle hits a gold nucleus in a head-on collision, the two would come to a rest for a very brief moment and then the particle would bounce straight back. This is describing a hypothetical situation proposed for Rutherford's gold foil experiment where he confirmed a small positively charged nucleus was present in atoms.
Alpha particles are composed of two neutrons and two protons, so they have a positive charge. When the alpha particles bounced straight back from the gold foil, this indicated that they had hit a particle of like charge, in other words a positively charged particle in the gold foil, which repelled the alpha particle.
Through the Gold Foil Experiment, he discovered that when Gold Atoms were deflected off of tin foil, some of them must have bounced. He noticed this because of a dense center in the atoms, which he noted to be the nucleus. Because of this, he is considered the discoverer of the nucleus. he had a 1cher he was a dick thanks did I help?
