What else can I help you with?
In Thomson's plum pudding model what do the plums represent?
The plums represent the electrons, which has a negative charge.
What are three types of subatomic particles are and?
Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919
When was Tom Thomson born?
Tom Thomson was born on August 5, 1877.
When was Peter G. Thomson House created?
Peter G. Thomson House was created in 1907.
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.
What experimental evidence did Thomson have atoms of all elements contain electrons?
The deflection of cathodic rays was the source of inspiration for Thomson.
What evidence convinced J.J Thomson that an atom consist of more than electrons?
The evidence for JJ Thomson was that the plum pudding model could not predict why atoms absorbed and emitted spectral lines.
How did J. J. Thomson change the atomic model based on his experimental results?
He described the atom as a sea of positive charge sprinkled with electrons
What observation did Thomson make to suggest that an electron has a negative electric charge?
The deflection of cathodic rays was the source of inspiration for Thomson.
Why did George Paget Thomson win The Nobel Prize in Physics in 1937?
The Nobel Prize in Physics 1937 was awarded jointly to Clinton Joseph Davisson and George Paget Thomson for their experimental discovery of the diffraction of electrons by crystals
. J. J. Thomson and experiments provided evidence that an atom .?
a cathode ray
What evedence convinced JJ Thomson that an atom consists of more than electrons?
The evidence for JJ Thomson was that the plum pudding model could not predict why atoms absorbed and emitted spectral lines.
Why did J Thomson reason that electrons must be a part of the atoms of all elements?
Cathode rays are negatively-charged particles.
Who named electrons called electrons?
j.j. Thomson
Who scientist discovery the electrons?
J.J. Thomson is credited with discovering electrons in 1897 through his cathode ray tube experiments. Thomson's work paved the way for the understanding of atomic structure and the development of the atomic model.
How did J.J. Thomson discover the electrons?
Thomson was experimenting with currents of electricity inside empty glass tubes.
What did Thomson discover about the electron?
J. J. Thomson is credited with the discovery of electrons.
