Learn about the plum pudding model, also known as Thomson atomic model, which describes atoms as spheres of positive charge with embedded electrons. Find out how this model was developed, supported, and abandoned by scientists in the early 1900s.
What is the Plum Pudding Model? A plum pudding model is a historical scientific model of the atom that was proposed by J.J. Thomson in 1904, shortly after he discovered the electron.
The plum pudding model was the first scientific model of the atom with internal structure, proposed by J. J. Thomson in 1904. It postulated that atoms were spherical and that electrons were distributed uniformly throughout the atom, like raisins in a plum pudding.
Plum pudding is an English dessert similar to a blueberry muffin. In Thomson's plum pudding model of the atom, the electrons were embedded in a uniform sphere of positive charge, like blueberries stuck into a muffin.
Learn how Thomson discovered the electron and proposed a model of the atom with negative plums in a positive pudding. Find out how this model failed to explain the emission spectra of elements and was replaced by Rutherford's nuclear model.
Learn about the plum pudding model of J J Thomson, which suggested that atoms were made of positive 'dough' with negative electrons. Find out how this model explained static...
Learn about the Plum Pudding Model, a 19th century atomic theory proposed by J.J. Thomson based on his experiments with cathode rays. Find out how it was developed, what it looked like, and why...
Thomson's model of the atom, also known as the plum pudding model, envisioned electrons as blueberries in a jelly-like positive substance. It was disproved by Rutherford's gold foil experiment and replaced by more accurate models.
Learn about the plum pudding model of the atom, which was proposed by J. J. Thomson based on his discovery of the electron. Find out how this model was challenged by Rutherford's experiments with alpha and beta particles.
Atomic model, in physics, a model used to describe the structure and makeup of an atom. Atomic models have gone through many changes over time, evolving as necessary to fit experimental data. ... He used his discovery to strongly support the so-called “plum-pudding” model of atomic structure first proposed by Lord Kelvin. The model ...
