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.
The Rutherford atomic model has 2 main parts: the nucleus, and the atom’s remaining space, occupied by electrons. According to the model, the nucleus is a very small portion of the atom’s volume. It occupies a small space in the very center of the atom. Protons and neutrons make up the nucleus and define the atom’s chemical properties.

23 de abr. de 2024 · Ernest Rutherford (born August 30, 1871, Spring Grove, New Zealand—died October 19, 1937, Cambridge, Cambridgeshire, England) was a New Zealand-born British physicist considered the greatest experimentalist since Michael Faraday (1791–1867). Rutherford was the central figure in the study of radioactivity, and with his concept of the nuclear ...
Ernest Rutherford. Through his inventive experimental work Rutherford made many new discoveries in both radioactivity and nuclear physics. Ernest Rutherford (1871–1937) postulated the nuclear structure of the atom, discovered alpha and beta rays, and proposed the laws of radioactive decay. He received the Nobel Prize in Chemistry in 1908.
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. Figure 3.4.2 3.4. 2 (a) The experimental setup for Rutherford's gold foil experiment: A ...
Rutherford’s new model for the atom is based on the experimental results obtained from the Geiger-Marsden experiments (also called the Rutherford gold foil experiment). The Geiger–Marsden experiments were performed between 1908 and 1913 by Hans Geiger (of Geiger counter fame) and Ernest Marsden (a 20-year-old student who had not yet earned his bachelor’s degree) under the direction of ...
