Groundbreaking Experiment
Rutherford Scattering was discovered through a groundbreaking experiment conducted by Ernest Rutherford and his colleagues in 1909.
The Plum Pudding Model
Prior to Rutherford’s experiment, the widely accepted model of the atom was the “Plum Pudding Model.” Rutherford’s findings revolutionized the understanding of atomic structure and revealed flaws in this model.
Alpha Particle Source
In Rutherford’s experiment, he bombarded a thin gold foil with alpha particles, which are helium nuclei consisting of two protons and two neutrons.
Unexpected Results
Rutherford expected the alpha particles to pass straight through the gold foil or be slightly deflected. However, he found that a small fraction of the particles were deflected at large angles, and some even bounced back.
Nuclear Model of the Atom
Rutherford’s experiment led to the development of the nuclear model of the atom, which states that atoms have a small, dense, positively charged nucleus at the center, surrounded by negatively charged electrons in an electron cloud.
Concentration of Charge
Rutherford’s observations of the deflected alpha particles led him to conclude that the positive charge and most of the mass of an atom are concentrated in its nucleus.
Empty Space
The results of Rutherford’s experiment also revealed that atoms are mostly empty space, with the electrons occupying a large volume around the nucleus.
Nuclear Forces
Rutherford’s model of the atom paved the way for the understanding of nuclear forces and the strong force that holds the nucleus together.
Size of the Nucleus
From his experiments, Rutherford estimated that the size of the nucleus is about 1/10,000th the size of the entire atom.
Proton Discovery
Rutherford’s work on atomic structure also led to the discovery of the proton, which is a positively charged particle found in the nucleus.
Nobel Prize in Chemistry
Ernest Rutherford was awarded the Nobel Prize in Chemistry in 1908 for his investigations into the disintegration of the elements and the chemistry of radioactive substances.
