- 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.

∙ 9y agoIn Thomson's plum pudding atomic model, the atom is composed of electrons (which Thomson called "corpuscles") surrounded by a soup of positive charge to balance the electron's negative charge. The electrons were thought to be positioned throughout the atom, but with many structures possible for positioning multiple electrons. It is important to note that this was before the discovery of the atomic nucleus.
In the Rutherford model, the atom is made up of a central charge (this is the modern atomic nucleus (though Rutherford did not use the term "nucleus" in his paper) surrounded by a cloud of orbiting electrons.
So basically the same thing except that Thompson's didn't have a nucleus and Rutherford's did. Also, Thompson's had electrons surrounding the positive charge, while Rutherford has them in rings around the nucleus.

∙ 10y agoSir J.J. Thompson, a renowned British scientist who actually â??discoveredâ?? the electron (the negative atomic particle), proposed his model of atomic structure in 1904, before the atomic nucleus was actually discovered. Thompson viewed the atom as a cloud-like mass in which the negatively-charged electrons (which he called â??corpusclesâ??) moved in rotating rings through a positively-charged â??soupâ??. This model was likened to an English dessert called a plum pudding, analogizing electrons with the raisins randomly scattered through the interior of the pudding. This model of atomic structure was largely discarded in 1911, based on discoveries made by Sir Ernest Rutherford. Rutherford was another important British physicist, and he amended, rather than disproved, Thompsonâ??s plum pudding model of atomic theory in 1911. He directed a series of experiments that detected a positively-charged central mass in the atom (eventually named the nucleus), around which the negatively-charged electrons moved. It is very similar to Thompsonâ??s plum pudding model, except that the electrons orbit the nucleic center, rather than throughout the atomic structure independently. The biggest differences in the theories lie in the distribution of the negatively- electrons and the presence of a central, positively-charged, massâ??the nucleus. What became known as the Rutherford-Bohr Model of atomic structure is what we envision when we think of what an atom â??looks likeâ??.

in plum pudding model there was no nucleus however in the nuclear model of an atom there is a nucleus.
in plum pudding model there were no shells or orbits while in nuclear model of an atom there are shells or orbits present.

What was Thompson's model of the atom called?
its called the plum pudding model
What was Thomson's model atom called?
The name was plum pudding.
What was Thomson's model of the atomic atom?
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.
How did Ernest Rutherford's atomic model change over time?
Ernest Rutherford's atomic model evolved from the plum pudding model to the nuclear model. In the plum pudding model, he proposed that atoms consist of a positively charged sphere with negatively charged electrons embedded in it. Upon conducting the gold foil experiment and observing that some alpha particles were deflected, he revised his model to include a dense, positively charged nucleus at the center of the atom, surrounded by orbiting electrons. This became known as the nuclear model of the atom.
What did the pudding represent in the plum pudding model?
The pudding in the plum pudding model represented a uniform positive charge that was spread throughout the atom, like the raisins in a plum pudding. This model was later proven incorrect when the discovery of the nucleus revealed that the positive charge is concentrated in a small, dense core at the center of the atom.
What is the difference between the plim pudding model and the nuclear model?
The plum pudding model, proposed by J.J. Thomson, describes an atom as a uniform positive sphere with electrons embedded throughout, like plums in a pudding. The nuclear model, proposed by Rutherford, states that an atom has a dense positively charged nucleus at its center where most of its mass is concentrated, with electrons orbiting around it. The key difference is the distribution of positive charge in the atom: uniformly spread in the plum pudding model and concentrated in the nucleus in the nuclear model.
What are the major difference between the plum pudding and planetary models of the atom?
The plum pudding model of an atom has not a nucleus; in 1904 the nucleus, protons, neutrons were not discovered. See the link below.
What is the plum pudding model different from the nuclear model?
No, the only sub-atomic particle in this atomic model was the electron (at the time called the "corpuscle"). This particle was assumed to be in a positive "gel" like a nut within a pudding.
What is the difference between Thomsons atomic model and Rutherfords atomic model?
Thomson's atomic model (the "plum pudding" model) proposed that electrons were embedded in a positively charged sphere. Rutherford's atomic model (the nuclear model) suggested that the atom is mostly empty space, with a dense, positively charged nucleus at the center and electrons orbiting around it. Rutherford's model overturned Thomson's model by demonstrating the existence of a small, dense nucleus at the center of the atom.
What are the differences between the plum pudding and planetary models of the atom?
The plum pudding model proposed by J.J. Thomson suggests that electrons are embedded in a positively charged sphere, similar to plums in a pudding. In contrast, the planetary model by Niels Bohr suggests that electrons orbit the nucleus in circular paths, similar to planets orbiting the sun. The key difference is that the plum pudding model does not account for discrete electron orbits or quantized energy levels, which are central to the planetary model.
What are the three subatomic models?
The three subatomic models are the plum pudding model, the nuclear model, and the current model known as the quantum mechanical model. These models describe the structure of the atom and the arrangement of subatomic particles within it.

What was JJ Thomsons 1904 model called?
JJ Thomson's 1904 model was called the "plum pudding model." This model described the atom as a sphere of positive charge with electrons embedded throughout, like plums in a pudding. It was later replaced by the more accurate Rutherford model.
