Who discovered that atoms contain subatomic particles?
J.J. Thomson discovered the first subatomic particle, the electron, in the late 19th century through his experiments with cathode rays. This discovery led to the understanding that atoms contain subatomic particles.
Who discovered the subatomic particles and in which order?
Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919 Neutron: James Chadwick, 1932
What did Rutherford's discover that Thomson did not understand?
That most of an atom's mass was packed in a central nucleus
What did Rutherford discover that Thomson did not understand?

Who are the scientists that discovered the atom?
There were four scientists that discovered the atom. These scientist were John Dalton, William Crooke, J.J. Thomson and Ernest RuthThere were four scientists that discovered the atom. These scientist were John Dalton, William Crooke, J.J. Thomson and Ernest Rutherford.
Which was discovered first proton or electron in which year and by whom?
the electron was first discovered in 1897 by Joseph john Thomson and the proton was discovered in 1913 by ernest Rutherford
Did jj Thomson or ernest Rutherford discover the neutron?
Neither J.J. Thomson nor Ernest Rutherford discovered the neutron. The neutron was discovered by James Chadwick in 1932 through experiments involving the interactions of neutrons with other atomic particles.
What did ernest Rutherford and jj Thomson do together?
Ernest Rutherford and J.J. Thomson worked together on research related to the structure of the atom. Thomson discovered the electron and proposed the plum pudding model of the atom, while Rutherford conducted the famous gold foil experiment that led to the discovery of the atomic nucleus. Their work laid the foundation for modern atomic theory.
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 is discovered the subatomic particles?
Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919
Who discovered binomial particles?
Binomial particles like protons, neutrons, and electrons were discovered by multiple scientists. The electron was discovered by J.J. Thomson in 1897, the proton was discovered by Ernest Rutherford in 1919, and the neutron was discovered by James Chadwick in 1932.
What did Rutherford discover that JJ Thomson did not understand?
Rutherford discovered the nuclear structure of the atom, proposing that it consists of a dense, positively charged nucleus surrounded by orbiting electrons. This contradicted Thomson's "plum pudding" model, which depicted the atom as a uniform sphere of positive charge with electrons embedded within it. Rutherford's gold foil experiment revealed that most of the atom's mass is concentrated in the nucleus, leading to a more accurate understanding of atomic structure. This shift laid the groundwork for modern atomic theory.
