WebApr 22, 2014 · Explanation: Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were indivisible particles, and Thomson's discovery of the electron proved the existence of subatomic particles. This ushered in a model of atomic structure referred to as the plum … WebJun 12, 2024 · The gold foil experiment by Ernest Rutherford proved that the positive charge of an atom is located in the nucleus, the small region that contributes most to the mass of the atom. Most of the atom is empty space, but the nucleus, however small, dictates the mass of the atom. To learn more about Ernest Rutherford’s gold foil experiment, …
WebBased on his experimental results, Rutherford made the following conclusions about the structure of the atom: The positive charge must be localized over a very tiny volume of the atom, which also contains most … WebScience. Chemistry. Chemistry questions and answers. Part A Which idea came out of Rutherford's gold foil experiment? Elements have isotopes. O Most of an atom's mass is concentrated in a very small space. O Atoms of the same element have the same mass. O Atoms contain protons and neutrons. - Submit OC Request Answer ON.
WebKey Concepts and Summary. Rutherford’s famous gold foil experiment was performed by aiming α particles at a sheet of gold foil and observing whether the α particles passed … WebApr 25, 2024 · Features. The gold foil experiment consisted of a series of tests in which a positively charged helium particle was shot at a very thin layer of gold foil. The expected result was that the positive particles …
WebIn this experiment, a very thin sheet of gold foil is bombarded with alpha particles. Alpha particles are helium atoms with 2 protons, 2 neutrons, and 0 electrons. Because of this, the overall charge of an alpha particle is +2. Since the alpha particles deflected backwards, a powerful force within the atoms of the gold foil must have repulsed it.
WebIn summary, the significance of Rutherford’s gold foil experiment was that it disproved the current model of the atom, J. J. Thompson’s plum-pudding model (I don’t have time to go into why it was called that – look it up) and led the way to our current understanding of atoms.
