The plum pudding model was wrong because it incorrectly suggested that the atom was a uniform, positively charged sphere with negatively charged electrons scattered throughout, like plums in a pudding. This model was disproven by the results of the Rutherford gold foil experiment, which showed that the atom has a small, dense, positively charged nucleus at its center, with electrons orbiting around it.

What was JJ Thomson's contribution to the periodic table?
JJ Thomson is known for discovering the electron, which led to the development of the plum pudding model of the atom. His work helped to provide a better understanding of atomic structure, but he did not directly contribute to the organization of the periodic table.
What did Rutherford scattering experiment reveal about atoms?
The Rutherford scattering experiment showed that atoms have a tiny, positively charged nucleus at their center surrounded by mostly empty space. This experiment led to the discovery of the atomic nucleus and helped establish the model of the atom as mostly empty with a dense nucleus at its core.
Rutherford's experiment included bombarding thin gold foil with alpha particles based on this research he concluded that?
Rutherford concluded that the atom is mostly empty space with a small, dense nucleus at the center. He also proposed the nuclear model of the atom, where electrons orbit the nucleus in a mostly empty space. This experiment laid the foundation for the modern understanding of atomic structure.
Have the models of atoms changed over the years?
The pretty universally accepted model from the time we first began to suspect (with some actual evidence, as opposed to being ancient Greeks pulling theories out a posteriori) that there were such things as atoms was that they were small, indivisible ... well, probably spheres. At least some of them were probably spheres, anyway.Around 1900 it became clear that while "small" was still true, "indivisible" was ... not so much. This lead to several competing theories that came out all about the same time (within a decade or so, anyway; 1902 to 1911): the cubic model, the "plum pudding" model, the "Saturnian" model, and the "Rutherford" model. All of these were attempts to explain the newly-discovered electrons and what exactly they were doing inside atoms.In 1913 Niels Bohr modified the Rutherford model a bit (incorporating some pieces of the Saturnian model as well) and came up with the Bohr model, which proposed that the electrons orbited a concentration of positive charge in the center of the atom in well-defined circular orbits. The Bohr model accounted for the fact that the electrons didn't immediately radiate energy and spiral into the nucleus by proposing that they were confined by ... something ... into specific orbits having characteristic energies. An electron could jump from one orbit to another (provided there was a space open), but only by giving off energy exactly equal to the difference in energy between the two orbits. This accounted for the observed phenomenon that atoms did in fact give off energy of very specific, or quantized, values.There were still problems with the Bohr model, one of which was that there didn't seem to be any particular reason the energy levels should happen to be what they were, so the Bohr model eventually disappeared in favor of the current quantum mechanical model, which describes the electrons as being in eigenstates of the time-dependent Hamiltonian equation, accounting precisely for their energies.

Why was the plum pudding model of the atom not successful?
There are a few reasons why Thomson's atomic model failed. It did not consider the reasoning behind atomic reactions or neutrality. It was just a visual he created with electrons placed haphazardly on a proton base. That arrangement is why it is commonly known as the plum pudding or raisin bun model.

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.
How do you know geocentric model is wrong?
"Models" aren't wrong; they are "more useful" or "less useful" for the intended purposes. The geocentric model is quite useful, for the purpose of celestial navigation, for example. It makes the math easier. But the geocentric model doesn't really describe what's going on in the solar system, where the Earth and other planets orbit the Sun. Of course, the "heliocentric", or "sun-centered" model is only useful for describing things within our solar system; it doesn't model other stars or the rest of the galaxy or universe accurately.
Why is the Bohr model wrong and what are the implications of its inaccuracies in understanding atomic structure?
The Bohr model is considered wrong because it does not fully explain the behavior of electrons in atoms. It simplifies the structure of atoms by suggesting that electrons orbit the nucleus in fixed paths, which contradicts the principles of quantum mechanics. This inaccuracy has implications in understanding atomic structure as it fails to account for the wave-like behavior of electrons and their uncertainty in position and momentum. This limits our ability to accurately predict the behavior of atoms and molecules, hindering advancements in fields such as chemistry and materials science.
What are common mistakes to avoid when making rice pudding?
Common mistakes to avoid when making rice pudding include overcooking the rice, using the wrong type of rice, not stirring frequently enough, and adding too much sugar or liquid.
How did Thompson explain the over all neutral charge of the atom?
Hepostulated (he was wrong) the existence of a 'sticky' substance like pudding that had a positive charge that the electrons was stuck in. Like plum pudding. Electrons were like plums actual particles with negative charges. The pudding was just a smear of stuff with a positive charge and held the atom together.
What simile is used describing poking out the cyclops eye in The Odyssey?
This may be wrong... "...as a shipwright turns a drill..." (line293)
Do Chinese people eat rice pudding at new year?
Not 100% sure but probably. They like rice. You didn't hear that from me if it's on your homework and you get it wrong :)
How are atoms identical?
they are not identical. Dalton's model was wrong.
How do you fix a be be gun?
It all depends on the model and what is wrong with it.
