What is the difference between the plim pudding model and the nuclear model?
The "plum pudding" (as they called it) model suggest's that the electrons were dispersed throughout the atom. Where as the nuclear model has positively charged protons which are present in the center of an atom (called the nucleus)
What did jj Thomson think the atom looked like?
J.J. Thomson proposed the "plum pudding" model of the atom, where electrons were embedded in a positively charged sphere, similar to plums in a pudding. This model suggested that the atom was a uniform, positively charged structure with negatively charged electrons scattered throughout.
What did Rutherford discover that Thomson did not understand?
That most of an atom's mass was packed in a central nucleus
What was the plum-pudding atomic model?
The plum pudding model of the atom, forwarded by J.J. Thomson, stated that the atom was like a plum pudding. The negatively charged electrons were evenly distributed throughout a positive "web" or "soup" much like plums in plum pudding are distributed here and there in the pudding. It was Rutherford, based on his observations with the gold foil experiment, who was able to push this theory aside and cause a shift in thinking to the idea that most of the mass of the atom was concentrated in a small volume within a given atom.
How is the Bohr atomic model different from the plum-pudding model?
In Bohr's model , the atoms mass is found at its center instead of distributed throughout.this is for apex
Where is most of mass in the plum pudding model?
In the plum pudding model, most of the mass is thought to be concentrated in a diffuse, positively charged "pudding" that fills the atom. This pudding is interspersed with negatively charged electrons, resembling plums within the pudding. The model, proposed by J.J. Thomson in the early 20th century, suggests that the mass of the atom is primarily due to this positive charge, with the electrons contributing to the overall structure rather than mass. However, this model has since been replaced by the more accurate nuclear model of the atom.

What is the origin of the name of the element rutherfordium?
Named for the famous chemist Ernest Rutherford who improved on the "plum pudding" model of the atom by postulating a nucleus which contained most of the atom's mass.
What is the plum pudding model and who come up with it?
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 the Thomson model of the atom?
J.J. Thompson's model of the atom is also known as the "plum pudding" model. Thompson modeled the atom as a mixture of positive protons amongst negatively charged electrons.Ernest Rutherford proved this model to be incorrect when he showed that the positive protons of an atom are located in the central nucleus. If the nucleus of a hydrogen atom were expanded to the size of a tennis ball, the electrons surrounding the nucleus would be (on average) several kilometers away from the nucleus.
What is the plum modeling?
It was proposed by "J.J. the Jet Plane Thompson" in 1904 as a model of the atom. It consisted of a positive mass [pudding] with little negative charges scattered throughout
What model replaced the plum pudding model?
The plum pudding model was replaced by the Rutherford model of the atom. In 1911, Ernest Rutherford conducted his gold foil experiment, which demonstrated that atoms have a dense, positively charged nucleus surrounded by electrons. This shifted the understanding of atomic structure from the diffuse distribution of mass in the plum pudding model to a more concentrated nucleus with electrons orbiting around it, laying the groundwork for the modern atomic model.
What was Ernest Rutherford model of the atom?
Ernest Rutherford proposed the nuclear model of the atom in 1911, which suggested that an atom consists of a small, dense, positively charged nucleus surrounded by orbiting electrons. This model was based on his gold foil experiment, which demonstrated that most of an atom's mass and positive charge is concentrated in its nucleus.
What did Rutherford discover that Thomson did not understand?
That most of an atom's mass was packed in a central nucleus
How was rutherfords model similar to thomsons model and how was it different?
Rutherford's model was similar to Thomson's model in that both described atoms as having a positively charged center (nucleus) surrounded by negatively charged electrons. However, Rutherford's model differed in that he proposed that the majority of an atom's mass and positive charge was concentrated in the nucleus, with electrons orbiting around it, while Thomson's model suggested that the positive charge was uniformly distributed throughout the atom.

The plum pudding model of the atom, forwarded by J.J. Thomson, stated that the atom was like a plum pudding.
