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.

Rutherford changed Thomson's model of the atom because his gold foil experiment showed that most of the atom's mass and positive charge were concentrated in a small, dense nucleus. This contradicted Thomson's "plum pudding" model, in which positive charge was thought to be evenly distributed throughout the atom.

How did thomsons experiment change daltons atomic model?
Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were in.
What is the purpose of the Rutherford experiment?
The purpose of the Rutherford experiment was to investigate the structure of the atom. By bombarding a thin gold foil with alpha particles and observing their scattering patterns, Rutherford discovered that atoms have a small, positively charged nucleus at the center surrounded by mostly empty space with electrons orbiting around it. This experiment revolutionized our understanding of atomic structure.
Did Ernest Rutherfords results fit with J.J Thomsons view of the atom?
Ernest Rutherford's results did not fit with J.J. Thomson's view of the atom. While Thomson proposed the "plum pudding" model with evenly distributed positive charge throughout the atom, Rutherford's gold foil experiment showed that the positive charge is concentrated in the nucleus at the center of the atom, with electrons orbiting around it.
What is the difference between Thomsons atomic model and Rutherfords atomic model?
Thomson's model was the "Plum Pudding model" because it had electrons "floating" around in the ball, but Rutherford's model shows the electron shells, the nucleus, and the molecular particles: neutron, proton, and electron. Hope this helps!
What discovery lead the scientists to question john daltons model of the atom and to favor jj Thomsons model?
JJ Thomson's discovery of electrons indicated that atoms were not indivisible.

This experiment revolutionized our understanding of atomic structure.
How did Rutherfords findings change Thomsons plum pudding model?
Rutherford supposed that the atom had a central positive nucleus surrounded by negative electrons.
How did Rutherfords model of the atom different from thomsons?
The Rutherford model involve a positive nucleus separated from electrons.
Who atomic model determined that an atoms positive charge is concentrated in the atoms center?
This is the Rutherford model.
How was bohrs atomic model similar to Rutherford's model?

How did Ernest Rutherford's gold foil experiment change the model of the atom?
Ernest Rutherford's gold foil experiment showed that atoms have a small, dense, positively charged nucleus at the center, with most of the atom being empty space. This led to the development of the nuclear model of the atom, overturning the previous plum pudding model and suggesting that electrons orbit the nucleus.

What scientific inquiry skill was Rutherford using in selecting Thomson's model for investigation?
Thomsons model is sometimes called the plum pudding model. Rutherfords results that while most alpha particles were undeflected some alpha particles bounced back
How does Rutherford's model of atoms explain the deflection of alpha particles by gold foils?
Rutherford's model of the atom suggested that atoms have a small, dense, positively charged nucleus at the center. When alpha particles (positively charged) were shot at gold foil, some were deflected at large angles or even reflected back. This indicated that the positive charge and mass of the nucleus were significant enough to affect the trajectory of the alpha particles.
