Apr 2, 2014 · A pioneer of nuclear physics and the first to split the atom, Ernest Rutherford was awarded the 1908 Nobel Prize in Chemistry for his theory of atomic structure.
This was done through his discovery and interpretation of Rutherford scattering during the gold foil experiment performed by Hans Geiger and Ernest Marsden, resulting in his conception of the Rutherford model of the atom.
The atomic nucleus shown expanded more than 10,000 times its size relative to the atom; electrons have no measurable diameter. The Rutherford model was devised by Ernest Rutherford to describe an atom. Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson 's plum ...
Physicist Ernest Rutherford envisioned the atom as a miniature solar system, with electrons orbiting around a massive nucleus, and as mostly empty space, with the nucleus occupying only a very small part of the atom. The neutron had not yet been discovered when Rutherford proposed his model, which had a nucleus consisting only of protons. (more)
Aug 10, 2022 · In 1911, Rutherford and coworkers Hans Geiger and Ernest Marsden initiated a series of groundbreaking experiments that would completely change the accepted model of the atom. They bombarded very thin sheets of gold foil with fast moving alpha particles.
The Rutherford gold foil experiment, also known as the scattering experiment, led to the creation of the model and explained the parts of the atom. In 1909, graduate student Ernest Marsden (under Ernest Rutherford’s supervision) fired alpha particles at a gold foil piece.
This led Rutherford to propose the nuclear model, in which an atom consists of a very small, positively charged nucleus surrounded by the negatively charged electrons. Based on the number of α particles deflected in his experiment, Rutherford calculated that the nucleus took up a tiny fraction of the volume of the atom.
