Plum Pudding Model Definition: The Plum Pudding Model is defined as an early scientific attempt to describe the atom, conceptualizing it as a sphere of positive charge with negatively charged electrons embedded within it. Experimental Foundations: This model was based on J.J. Thomson’s cathode ra...

to understand how a color is created, we must first understand the structure of an atom, which itself — being an object a million times thinner than a strand of human hair – can be comprehended only through descriptions. J.J. Thomson’s Plum Pudding Model was one such description of an...
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 ...
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 ...

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 plum pudding model, which describes that atoms are unif...
Though defunct by modern standards, the Plum Pudding Model represents an important step in the development of atomic theory. Not only did it incorporate new discoveries, such as the existence of the electron, it also introduced the notion of the atom as a non-inert, divisible mass. Henceforth...
