anyone familiar with this? Rutherford (Ernest) had a famous experiment with the gold leaf and some radiactive source. Anyone want to calloborate? Becuz i m not so clear on wat that is
reilly said:You might try an atomic or nuclear physics book. Simply stated, by bombarding the foil with alpha particles, Rutherford demonstrated that nucleii are very small, and that atoms are mostly space. The so called plum pudding model was disproved.
Bohr, who worked with Rutherford, saved the idea of a "planatary model" of the atom, with the astonishing idea of quantum stability, and derived the formulas of the hydrogen spectra to substantial accuracy. Rutherford discovered the nucleus, Thompson discovered the electron, and Bohr gave the first successful theory of the atom based on electrons and nucleii.

Rutherford's Gold Leaf experiment was a series of experiments conducted by physicist Ernest Rutherford in 1911 to investigate the structure of the atom.
The purpose of Rutherford's Gold Leaf experiment was to test the existing model of the atom, the Thomson model, and to discover the true structure of the atom.
Rutherford's Gold Leaf experiment involved shooting alpha particles at a thin gold foil and observing their deflection. The alpha particles were released from a radioactive source and were detected by a screen coated with zinc sulfide.
The results of Rutherford's Gold Leaf experiment showed that most of the alpha particles passed straight through the gold foil, but a small percentage were deflected at large angles. This led Rutherford to conclude that the atom has a small, dense, positively charged nucleus surrounded by mostly empty space.
Rutherford's Gold Leaf experiment revolutionized our understanding of the atom and led to the development of the modern atomic model. It showed that the atom is mostly empty space, with a small, dense nucleus at its center containing the majority of its mass and positive charge. This experiment also paved the way for further advancements in nuclear physics and led to the discovery of the proton and neutron.
