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.
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.
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.
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.
The nickname for Thompson's atomic model is the "plum pudding model." This model suggests that atoms are made up of a positively charged "pudding" with negatively charged electrons embedded within it, resembling plums in a pudding.
I think you're referring to JJ Thomson's model. It is more oftenly called the 'plum-pudding model'.
Yes. Absolutely. We are fooling our children. We need to come clean with our children. The time is now! Rise up!
The plum pudding model ddi not employ the concept that the nucleus was the centre of the atom and that the electrons were not randomly placed around the nucleus but were in orbits in different energy levels. The Bohr model introduced the concept that a certain number of electrons could occupy each energy level and no more ie 2 8 8 18 18 32
If the Thomson model of the atom had been correct, Rutherford would have observed that most of the alpha particles passed straight through the atom without being deflected or scattered. This would indicate a uniform distribution of positive charge throughout the atom, as proposed by Thomson.
No, the concept of the electron cloud was proposed by Schrödinger and Heisenberg as part of the development of quantum mechanics in the early 20th century. J.J. Thomson, on the other hand, is known for his discovery of the electron and his plum pudding model of the atom.
It is J.J. Thompson that is given credit for the discovery of the electron, and he theorized that these negative charges were embedded in a positively charged cloud like plums in a plum pudding. This gave rise to the "plum pudding" model of the atom, a theoretical structure that was swept aside by the Geiger and Marsden gold foil experiment.
J. J. Thomson's scientific ideas were called the "plum pudding model" or the "Thomson model." This model proposed that atoms were composed of a positively charged material with negatively charged electrons embedded within it, resembling plums in a pudding.
The first atomic model based on experimentation was developed by J.J. Thomson in 1897. Thomson's model, known as the "plum pudding model," proposed that atoms were made up of a positively charged material with negatively charged electrons scattered throughout, similar to the seeds in a watermelon.
