The plum pudding model of the atom by J. J. Thomson, who discovered the electron in 1897, was proposed in 1904 before the discovery of the atomic nucleus. In this model, the atom is composed of electrons (which Thomson still called "corpuscles", though G. J. Stoney had proposed that ...

The plum pudding model suggested that an atom consists of a sphere of positive charge, called the pudding, with electrons embedded in it, like plums in a desert. The electrons were arranged in shells and balanced the positive charge of the sphere. ...
Thomson's discoveries raised questions concerning the nature of the atom. He demonstrated that the atom is not the simplest unit of matter; rather, it has a structure. Thomson's atomic theory has informally been called the "plum-pudding" model, but the early history of this expression has ...
The Plum Pudding Model, also known as Thomson’s Plum Pudding Model, is also a scientific model for explaining the arrangement of subatomic particles. This model was first proposed by a British physicist Sir J. J. Thomson in 1904. This model was stated soon after the discovery of the ...

How did Thomson come up with the plum pudding model? William Thomson knew that atoms had an overall neutral charge. After JJ Thomson discovered the electron, William Thomson reasoned that there must be a positive charge within an atom to balance the negative charge of electrons. He created the...
The electrons were the negative plums embedded in a positive pudding. The name stuck, and the model is still commonly referred to as the Plum Pudding Model. Knowledge can either be derived by acquaintance, such as the color of a tree, or — if the phenomenon is impossible to “become acqu...
