The plum pudding model suggested that the electrons were dispersed throughout the atom (like Chocolate Chips in a cookie) and the space was positively charged so that in the end the atom was neutral. Today, people know that the electrons are in a "cloud" around the atom and the protons (and neutrons) are in the nucleus, at the center of the atom.

What is JJ Thomson model called?
J.J. Thomson, also known for discovering the electron, also proposed a model of the atom in 1904. This model is known as both the plum pudding model and the blueberry muffin model, and it posits that the atom is made up of electrons which are surrounded by a "pudding" of positive charges.
How did jj Thomson come up with the idea that an atom could shape like a plum pudding?
In Thomson's "Plum Pudding Model" each atom was a sphere filled with a positively charged fluid. The fluid was called the "pudding." Scattered in this fluid were electrons known as the "plums." The radius of the model was 10-10 meters. Thomson suggested that the positive fluid held the negative charges, the electrons, in the atom because of electrical forces. However, this was only a very vague explanation and failed to provide any definite answers.
Which scientist or scientists came up with the Electron Cloud nodel of the atom?
I think you're referring to JJ Thomson's model. It is more oftenly called the 'plum-pudding model'.
If the Thomson model of the atom had been correct Rutherford would have observed?
Before we state the results of the Rutherford gold foil experiment based on the correctness of the Thomson plum pudding model, let's back up and review just a bit. Atoms were thought to be made up of electrons distributed in a positive "matrix" of sorts. With the electrons "evenly distributed" throughout the volume of the atom, a parallel or comparison was made to plum pudding. The plums, which were "scattered" throughout the pudding, were thought of as the electrons in the atom. This is the basis for the plum pudding model of the atom. The gold foil experiment that Rutherford proposed was set up, and alpha particles were "fired" at gold foil from an alpha source (alpha emitter). As the alpha particles were known to be massive compared to an electron, an experiment on atoms conforming to the plum pudding model of the atom would show that the alpha particles zip right through. There would be nothing anywhere near as massive as an alpha particle in the plum pudding atom to stop or scatter them. All the alpha particles would strike the target screen behind the foil in a direct line from the source. When the experiment was actually conducted, most of the alpha particles struck as expected. But a few were scattered in different directions, and this was "impossible" if the atom was constructed as suggested by the plum pudding model. What internal structure in the plum pudding atom could possibly deflect (scatter) a few (or any!) alpha particles? The plum pudding model was set aside, and Rutherford's suggestion was that most of the mass of the atom was concentrated as a positive charge in the center in what we call a nucleus.
Is plum pudding a man in strawberry shortcake?
Yes. Absolutely. We are fooling our children. We need to come clean with our children. The time is now! Rise up!
Atoms are made up of negatively charged electrons embedded in a positively charged sphere?
in plum pudding model why thomson has considered electrons embedded in positively charged sphere?
Which scientist envisioned the atom as a ball of postive charge with electrons embedded in it?
This is J. J. Thompson's model. I've heard it referred to as the 'plum pudding model', 'raisin pudding model', and 'chocolate chip cookie model'. You may learn more about J. J. Thompson at http://en.wikipedia.org/wiki/J_J_Thompson
What is the difference between a Bohr diagram and Lewis diagram?
Electrons dot diagrams/Lewis Dot Diagrams show the symbol for the element surrounded by dots that show the number of valence electrons. Bohr diagrams show the amount of total number of electrons in an element, filling each shell up until the final one.
What is the difference between the plum pudding and the nuclear model of an atom?
- Plum pudding model: electrons are included in a positive sphere.- The Bohr model consider that electrons are in a continuous movement around the atomic nucleus.
Descibe Thomson atomic model?
J.J. Thompson was the person who suggested the plum pudding model for the atomic structure. He declared that the electrons are located between a cloud of the positive charges. This model was proven incorrect from the alpha particle experiment done by Ernest Rutherford.
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.
What did Rutherford did?
Ernest Rutherford was a brilliant scientist who, among other things, discovered what was inside an atom, putting paid to the previously accepted "plum pudding" model. By setting up a classic experiment involving gold foil and an alpha particle emitter, he noticed that atoms consisted of a dense central region (the nucleus), which possessed a positive charge.
