according to jj thomsons model of an atom,an atom consists of a positively charged sphere with electrons in it.however,it was later found that positively charged particles reside at the center of the atom called nucleus,and the electrons revolve around the nucleus.
The Rutherford model involve a positive nucleus separated from electrons.
a bohr model is shown by taking the number of valence electrons in an atom and put it in a circle around the atomic symbol of an atom
J.J. Thomson's ideas were called the plum-pudding model. This model described how electrons were evenly distributed throughout the atom.
If i remember correctly, Dalton's focuses more on the nucleus while Thompson's focuses more on electrons. But I'm not sure. well in 1803 John Dalton makes a strong case that atoms are small, solid balls and Joeseph John Thompson discovers electrons, and developed plum pudding model of an atom..... Dalton says that nothings smaller than the atom, but Thompson says that electrons are.
The Bohr model of the atom was a planetary model.
The Rutherford model involve a positive nucleus separated from electrons.
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
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!
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.

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.
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.
The charge of the negative charge of electrons surrounding the nucleus of the atom.

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.
