According to Thomson's model, an atom can be considered as a sphere of uniformly distributed positive charge in which there are electrons distributed symmetrically. The electrons must be held by the positive charges by electrostatic forces. The mutual repulsions between the electrons are balanced by the force of attraction towards the centre of the sphere. In an atom with a single electron like the hydrogen atom, the electron must be situated at the centre of the positive sphere.

Who opposed J J Thomsons atomic theory?
Some scientists who opposed J.J. Thomson's atomic theory included William Prout, Ernst Rutherford, and Max Planck. These scientists challenged aspects of Thomson's model, such as the presence of subatomic particles within the atom.
What was JJ Thomsons model of the atom called?
JJ Thomson's model of the atom is called the "plum pudding model." It suggested that atoms were made up of positive and negative charges distributed throughout a neutral, positively-charged background.
What did J. J. Thomsons experiments provided evidence about an atom?
J. J. Thomson's experiments provided evidence for the existence of electrons as subatomic particles within the atom. This led to the plum pudding model of the atom, where electrons were embedded in a positively charged "pudding." These experiments laid the foundation for our understanding of atomic structure.
Is the statement An atom consists of a dense nucleus surrounded by a cloud of electrons best described as a law or hypothesis or a theory?
The statement "An atom consists of a dense nucleus surrounded by a cloud of electrons" is best described as a theory in the field of atomic structure. The atomic theory explains the structure of atoms based on experimental evidence and scientific principles.
Did Ernest Rutherfords results fit with J.J Thomsons view of the atom?
Thomsons model is sometimes called the plum pudding model as he envisaged a soup of positive charge with negative charges, by then already called electrons swimming round. He came up with this idea in 1904."the atoms of the elements consist of a number of negatively electrified corpuscles enclosed in a sphere of uniform positive electrification"Rutherford following on from the famous scattering experiment with gold foil and alpha particles proposed that the positive charge was concentrated in a central nucleus.
How was Thomsons atomic theory different from Rutherfords 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.
What were Thomsons and rutherfords key discoverirs about the atom?
im awesome!
What aspect of Dalton's theory was supported by Thomsons findings?
the electron part
How did Rutherfords model of the atom different from thomsons?
The Rutherford model involve a positive nucleus separated from electrons.
Who opposed J J Thomsons atomic theory?
Some scientists who opposed J.J. Thomson's atomic theory included William Prout, Ernst Rutherford, and Max Planck. These scientists challenged aspects of Thomson's model, such as the presence of subatomic particles within the atom.
In Thomsons Raisin Bun model what were the electrical charges on the bun and the raisins?
The charge of the negative charge of electrons surrounding the nucleus of the atom.
How did Rutherfords findings change Thomsons plum pudding model?
Rutherford supposed that the atom had a central positive nucleus surrounded by negative electrons.
When was Thomsons Online Benefits created?
Thomsons Online Benefits was created in 2000.
What is the area of Thomsons Lake?
The area of Thomsons Lake is 5,380,000.0 square meters.
What were J. J. thomsons ideas called?
J.J. Thomson's ideas were called the plum-pudding model. This model described how electrons were evenly distributed throughout the atom.
How does the current model of the atom differ from j.j Thomsons model?
J.J. thomson's model doesn't have an electrons flowing around like how are planets orbit the sun. The current model has these things.
