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 ...
a dessert adored by the British. 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. However, it is also often called the Watermelon Model. I’m sure the connotation is obvious. ...
the Plum Pudding Model was born, so named because it closely resembled the English desert that consists of plum cake and raisins. The concept was introduced to the world in the March 1904 edition of the UK’s
Preparing plum pudding can take weeks, depending on the recipe. Some recipes steam the pudding, after which it is kept in a cooling place for several days before it is re-steamed and served. Even after it is served, families often keep leftovers until another big event of holiday, such as...

In 1899, Thomson published a description of his version of the atom, commonly known as the "plum pudding model." An excerpt of this paper is found on theChem Teamsite. Thomson's model of the atom included a large number of electrons suspended in something that produced a positive charge gi...
If atoms were structured according to the plum pudding model, where it just contained a mixture of positive and negative charges, the alpha particles should just fly straight through. Instead, Rutherford, Geiger and Marsden found that the alpha particles kept getting deflected, sometimes by a ...
However, Thomson also postulated that electrons were distributed throughout the atom, which was a uniform sea of positive charge. This became known as the "plum pudding model", which would later be proven wrong. This took place in 1909, when physicists Hans Gieger and Ernest Marsden (under th...
