Answer
Plum pudding model
Explanation
The plum pudding model was developed to incorporate the presence of electrons within a positively charged 'soup'.
Common mistake
Misunderstanding the Plum Pudding Model
Students often think the plum pudding model describes electrons embedded in a solid mass rather than a diffuse positive charge with electrons scattered throughout.
Clarify that the plum pudding model suggests a positive 'pudding' with negatively charged electrons as 'plums' distributed within it.
