Answer
Plum pudding model
Explanation
The discovery of the electron led to the plum pudding model, which depicted the atom as a ball of positive charge with negative electrons embedded in it.
Common mistake
Confusing Models
Students often confuse the plum pudding model with the nuclear model, thinking they describe the same structure of the atom.
To fix this, students should focus on the key differences: the plum pudding model depicts a positive sphere with electrons embedded, while the nuclear model shows a dense nucleus with electrons orbiting around it.
