Who discovered the nucleus and it's subatomic particles?
The nucleus was discovered by Ernest Rutherford in 1911 through his gold foil experiment. Subatomic particles in the nucleus, such as protons and neutrons, were later identified by other scientists such as James Chadwick and J.J. Thomson.
How is the work of Joseph John Thomson related to that of Ernest Rutherford?
Joseph John Thomson, while at the Cavendish Laboratory of the University of Cambridge, circa 1897, discovered the electron while studying cathode rays. His conclusion was that the electron was both a carrier of electricity and a component of all atoms. Ernest Rutherford began his work at Cavendish around the same time, working on radioactivity. Returning later to the Cavendish, around 1919, after his discovery of the nucleus, he succeeded Thomson as Cavendish Professor of Experimental Physics.

Who Evidenced the existence of subatomic particles?
For the particles in the atom: Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutheford, 1919
What kiwi split the atom?
Physicist Sir Ernest Rutherford, a New Zealand native, conducted the experiment that first split the atom at the University of Manchester in 1919. This pioneering work laid the foundation for nuclear physics and the development of atomic energy.
Who is the father of nuclear-physics?
Several people might claim this title but I would go for Ernest Rutherford. In 1907 Rutherford took the chair of physics at the University of Manchester. There along with Hans Geiger and Ernest Marsden he carried out the Geiger-Marsden experiment, which demonstrated the nuclear nature of atoms. It was his interpretation of this experiment that led him to the Rutherford model of the atom, with a very small positively-charged nucleus orbited by electrons. In 1919 he became the first person to transmute one element into another when he converted nitrogen into oxygen through the nuclear reaction 14N(α,p)17O. In 1921, while working with Niels Bohr (who postulated that electrons moved in specific orbits), Rutherford theorized about the existence of neutrons, which could somehow compensate for the repelling effect of the positive charges of protons by causing an attractive nuclear force and thus keeping the nuclei from breaking apart. Rutherford's theory of neutrons was proved in 1932 by his associate James Chadwick, who in 1935 was awarded the Nobel Prize in Physics for this discovery.
What scientist discovered positively charged subatomic particles?
Ernest Rutherford in 1919.
Who discovered the subatomic particles of proton?

Who is discovered the subatomic particles?
Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919
Who are the discovery of these 3 subatomic particles?
Particles in the atom: Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919
Why are scientists concerned about subatomic particles?
For the particles in the atom: Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919
Who discover subatomic particle?
There are 3 subatomic particles in an atom, electrons, protons, and neutrons. The first discovered was the electrons by J.J. Thomson in 1897. The second discovered was the protons by Ernest Rutherford in 1919. The third discovered was the neutrons by James Chadwick in 1932.
Who invented subatomic particles?
For the particles in the atom: Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919 The word "invented" is not adequate; correct is "discovered".
Who is discovered the nucleus and its subatomic particles?
The nucleus of an atom was discovered by Ernest Rutherford in 1911 through his gold foil experiment. Subatomic particles within the nucleus, such as protons and neutrons, were later identified by James Chadwick in 1932.
