The plum pudding model is an obsolete scientific model of the atom. It was first proposed by J. J. Thomson in 1904 [1] following his discovery of the electron in 1897 and subsequently rendered obsolete by Ernest Rutherford 's discovery of the atomic nucleus in 1911. The model tried to account for two properties of atoms then known: that there ...
Following the discovery of the electron, J.J. Thomson developed what became known as the "plum pudding" model in 1904. 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.
Jun 18, 2023 · The plum pudding model was an early attempt to explain the atom by J.J. Thomson in 1904. It suggested that an atom consists of a sphere of positive charge with electrons embedded in it. The model tried to account for the properties of atoms and matter, but it failed to explain some phenomena and experiments. It was soon replaced by Rutherford ...

The History of the Atomic Model: Thomson and the Plum Pudding. Expert. . 1. m. J.J Thomson contributed massively to the model of the atom and the modern day theory. His work involved the use of cathode ray tubes and identifying a particle lighter than the atom itself, the electron. Refresher: The atomic model originated in the 5th century BC ...

Oct 19, 2023 · 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 acquainted with” — by description.
The plum pudding model depicts the electrons as negatively-charged particles embedded in a sea of positive charge. The structure of Thomson's atom is analogous to plum pudding, an English dessert (left). Image from Openstax, CC BY 4.0.
