How is Thomson's model based on the experiment of passing alpha particles through the gold foil?
The results of this experiment led to the model of the atom called "Rutherford's model", rather than Thomson's model, which it basically disproved. Some of the alpha particles were deflected in ways that suggested to Rutherford that most of the atom's mass was concentrated in a positively charged "nucleus".
What did ernest Rutherford's model disprove?
Ernest Rutherford's model of the atom disproved the Plum Pudding Model proposed by J.J. Thomson. Rutherford's gold foil experiment led to the conclusion that the atom is mostly empty space with a small, dense nucleus at the center, which contradicted the idea of electrons being randomly distributed throughout the atom.
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.
What were rutherford's and Thomson's key discoveries about the atom?
Rutherford's key discovery was that the atom has a small, positively charged nucleus and is mostly empty space. Thomson discovered the electron and proposed the "plum pudding" model of the atom, in which electrons were embedded in a positively charged sphere.
How did Rutherford's theory change Thomson's theory?
Rutherford's theory significantly altered Thomson's earlier model of the atom by introducing the concept of a dense, positively charged nucleus at the center, surrounded by orbiting electrons. While Thomson's "plum pudding" model suggested that electrons were scattered within a diffuse cloud of positive charge, Rutherford's gold foil experiment demonstrated that most of an atom's mass and positive charge is concentrated in a small nucleus. This shift paved the way for the modern understanding of atomic structure, emphasizing the nucleus's role and leading to the planetary model of the atom.
What value did Rutherford's model of an atom have over Thomson's model?
Thomson said that charges are distriduted evenly in entitre atom. but Rutherford said that charges(electrons) are continuously revolving around the nucleus,a small region where the entire mass of atom is subjected to be. Thomson failed to put forward the concept of nucleus and orbitals.
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.
What did ernest Rutherford?
Ernest Rutherford is perhaps best known for his model of the atom. He developed his own model, based upon his research, to replace Thomson's plum-pudding model.
What did Rutherford discover that Thomson did not understand?
That most of an atom's mass was packed in a central nucleus
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.
Who are the scientist that develop of the concept of the atom?
Some of the key scientists who played a major role in developing the concept of the atom include John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr. Dalton proposed the atomic theory, Thomson discovered the electron, Rutherford conducted the famous gold foil experiment leading to the nuclear model of the atom, and Bohr developed the planetary model of the atom.

When did Ernest Rutherford propose the plum pudding model of the atom?
The ''plum pudding atomic model" is from J. J. Thomson, year 1904.

How many types of atom do you have?
You mean elements? So far scientists have brought out some 109 elements. If you mean atom model, then first Prout's model Then Thomson's, Rutherford's, Bohr's, Sommerfeld's. Finally vector atom model.
Who invented the present atom modle?
John Dalton was the one who invented atom model. Thomson, Rutherford, Bohr and de Broglie also helped him build it.
