short paragraph on plump pudding model
Answers
Explanation:
The plum pudding model is one of several historical scientific models of the atom. First proposed by J. J. Thomson in 1904[1] soon after the discovery of the electron, but before the discovery of the atomic nucleus, the model tried to explain two properties of atoms then known: that electrons are negatively-charged particles and that atoms have no net electric charge. The plum pudding model has electrons surrounded by a volume of positive charge, like negatively-charged "plums" embedded in a positively-charged "pudding".
this model, atoms were known to consist of negatively charged electrons. Though Thomson called them "corpuscles", they were more commonly called "electrons" which G. J. Stoney proposed as the "fundamental unit quantity of electricity" in 1891.[2] At the time, atoms were known to have no net electric charge. To account for this, Thomson knew atoms must also have a source of positive charge to balance the negative charge of the electrons. He considered three plausible models that would be consistent with the properties of atoms then known:[
