What is the plum pudding model?
Could you please elaborate on the concept of the plum pudding model? I'm intrigued to know how this model came to be and what it represents in the realm of atomic structure. Is it a metaphorical portrayal or a more literal depiction? Additionally, what are its key characteristics and how does it differ from other prevailing theories of atomic composition during its time? I'm particularly interested in how it shaped our understanding of matter and how it eventually evolved with the advent of new scientific discoveries.
Why was the plum pudding model replaced?
Why was the plum pudding model, a once widely accepted theory of the atomic structure, eventually replaced? Was it due to new discoveries that contradicted its assumptions? Or did technological advancements enable scientists to observe atomic structures more accurately, revealing flaws in the plum pudding model? Was there a particular experiment or breakthrough that prompted the shift towards a new understanding of the atom? As an inquirer seeking clarity, I am keen to understand the motivations and factors that led to the replacement of this historical scientific model.
