Rutherford scattering - Study guides, Class notes & Summaries

Ancient greek model of the atom Atoms are tiny solid spheres which cannot be divided. JJ Thompson Discovered the electron and developed the "plum-pudding" model of the atom plum pudding model of the atom atoms are balls of positively charge with negative electrons embedded in it Rutherford, Geiger, and Marsden carried out the alpha particle scattering experiment and developed the nuclear model of the atom Alpha particle scattering experiment Fired alpha particles at a thin sheet of go...

Included in these notes are the key definitions (e.g. critical mass, mass defect) as well as the theory and experimental procedure of the Rutherford scattering experiment. The differences between alpha, beta, and gamma radiation are also stated along with their uses and how to distinguish between them experimentally. The inverse square law for gamma radiation was also proved. Furthermore, equations and theory behind radioactive decay are stated as well as how the forces in the nucleus help keep ...

Ernest Rutherford was the co-worker and a student of J.J. Thomson regarding the structure of an atom. He performed a-particle scattering experiment to locate electrons and protons in an atom in 1911.
