In 1911 the existence of the atomic nucleus was discovered by Ernest Rutherford through his interpretation of the gold foil experiment conducted two years earlier by Hans Geiger and Ernest Marsden. In 1932 Dmitry Ivanenko proposed the proton-neutron model of the nucleus.

How where atoms discovered to be made of electrons?
1. Atoms are made from the atomic nucleus (protons plus neutrons) and electrons.2. For the discovery of electrons is credited J. J. Thomson in 1897.
Who proposed the protons?
No one proposed it. It IS about the atomic number.
Which statement describes James Chadwicks discovery He discovered that the atomic nucleus is a dense positively charged mass He discovered negatively charged atomic particles that were deflected by a?
an electrical neutral particle from the atomic nucleus
When did Marie and Pierre curie discover their atomic theory?
Marie and Pierre Curie did not discover the atom. John Dalton is credited with the discovery of the atom and J.J. Thomson with the discovery of the electron.
Who is given credit for discovering the existence of the neutal particle in the atom in 1932?
James Chadwick is credited with the discovery of the neutron in 1932. His experiments demonstrated the existence of this neutral particle within the atomic nucleus, contributing significantly to the understanding of atomic structure. Chadwick's work built on earlier theories but provided definitive evidence for the neutron's existence, leading to advancements in nuclear physics. His discovery earned him the Nobel Prize in Physics in 1935.

Rutherford's experiments led to the discovery of the?
Rutherford's experiments led to the discovery of the atomic nucleus. Through his gold foil experiment, he found that atoms have a small, dense, positively charged nucleus at their center and that the rest of the atom is mostly empty space. This discovery revolutionized our understanding of atomic structure.
Who came up with the idea of a nucleus of an atom?
The discovery of the nucleus is typically credited to Ernest Rutherford, an English physicist of the early 1900s. Rutherford first came up with the idea of a nucleus as a result of his gold foil experiments.
What was Sir Ernest Rutherford famous for?
Sir Ernest Rutherford was a pioneering physicist known for his contributions to the understanding of atomic structure and radioactivity. He is credited with developing the nuclear model of the atom and conducting the famous gold foil experiment, which led to the discovery of the atomic nucleus. Rutherford's work laid the foundation for modern nuclear physics.
Who is credited who discovery?
J.C. Adams and U.J.J. Le Verrier are credited with the mathematical discovery and D'arrest and Galle are credited with the observational discovery.
Who is credited with neptunes discovery?

What was the name of the scientist who was credited with the discovery of the cathode ray?
The scientist credited with the discovery of the cathode ray is J.J. Thomson. Thomson conducted experiments with cathode rays in the late 19th century and discovered the electron, which revolutionized our understanding of atomic structure.
What did chadwhicks experiment kead to the discovery of?
Chadwick's experiment led to the discovery of the neutron, which is a subatomic particle with no charge located in the nucleus of an atom. This discovery helped to further our understanding of atomic structure and the composition of matter.
What was ernest rutherfords greatest science achievement?
Opinions vary. The discovery of the atomic nucleus ("most of the atom is empty space")
