Question
The atom as a whole is electrically neutral", is a statement proposed by which atomic model:
✓
Answer
- Thomson's atomic model
Thomson proposed that : An atom consists of a positively charged sphere and the electrons are embedded in it.
Thus, the atom is visualized as a pudding or cake of positive charges with raisins (electrons) embedded into it.
Hence it is the raisin pudding model or watermelon model.
The negative and positive charges are equal in magnitude. So that atoms as a whole are electrically neutral.
