Who discovered the subatomic particles and in which order?
Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919 Neutron: James Chadwick, 1932
What main feature of Thomson atomic model was charged after Rutherford discoveries?
The main feature of Thomson's atomic model that was changed after Rutherford's discoveries was the location of the positive charge in the atom. Rutherford discovered that the positive charge was concentrated in a small nucleus at the center of the atom, rather than being spread out evenly throughout the atom as Thomson had proposed.
Who coined the word Proton?
The word "proton" was coined by Ernest Rutherford in 1920 during his experiments with radiation. Rutherford used this term to describe the positively charged particles he identified in the nucleus of an atom.
Why did Rutherford change Thomson's model of the atoms?
According to his Thompson's model, an atom was a sphere of positive matter that held electrons, so Rutherford discovered that an atom has a nucleus and that the nucleus contains most of the matter of the atom. Also that the atom has electrons, protons, and neutrons surrounding it.
When did julius plucker discover the electron?
Julius Plucker did not discover the electron. The electron was discovered by J.J. Thomson in 1897 through his experiments with cathode ray tubes.
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 discovered that Thomson did not understand?
That most of an atom's mass was packed in a central nucleus
What did Rutherford discover that Thomas did not understand?
That most of an atom's mass was packed in a central nucleus
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.
How did Rutherford's idea differ from Thomson's idea?
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
Was neils bohr jj Thomson's student?
No, Niels Bohr was not J.J. Thomson's student. Niels Bohr was a student of Ernest Rutherford, who was a colleague of J.J. Thomson. Bohr developed his own atomic model, known as the Bohr model, which built upon the work of Thomson and Rutherford.
Who did Niels Bohr work with?
JJ Thomson, Ernest Rutherford
What particle did Thomson discover?
Electrons
What other scientists did j j Thomson work with?
J.J. Thomson worked with several notable scientists during his career, including Sir William Ramsay, who he collaborated with to discover the noble gases; his student Ernest Rutherford, who went on to discover the nucleus of the atom; and his son George Paget Thomson, who won the Nobel Prize in Physics for his work on the wave-like properties of electrons.
What did Thomson discover about the electron?
J. J. Thomson is credited with the discovery of electrons.
How was Thomson's atomic theory differ from Rutherford atomic theory?
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
When did Ernest Rutherford discover rutherfordium?
Rutherfordium was not discovered by Ernest Rutherford.
