Commentary

Rutherford model The Rutherford model is a name for the concept that an atom contains a compact nucleus. Why does Rutherford model matter? This principle is one of the building blocks physicists use to explain the world. Without it, a whole cl ass of phenomena would have no mathematical description. Engineers, chemists, and astronomers all rely on it. Background: Rutherford model The Rutherford model is a name for the concept that an atom contains a compact nucleus. The concept arose after Ernest Rutherford directed the Geiger–Marsden experiment in 1909, which showed much more alpha particle recoil than J. J. Thomson's plum pudding model of the atom could explain. Thomson's model had positive charge spread out in the atom. Rutherford's analysis proposed a high central charge concentrated into a very small volume in comparison to the rest of the atom and with this central volume containing most of the atom's mass. The central region would later be known as the atomic nucleus. Rutherford did not discuss the organization of electrons in the atom and did not himself propose a model for the atom. Niels Bohr joined Rutherford's lab and developed a theory for the electron motion which became known as the Bohr model.
