• C. both A and B
• D. None of the above

Answer 1

The correct option is B

plum pudding model

Explanation:

J.J. Thomson proposed a model of an atom. The postulates of this model are:

• An atom consists of a positively charged sphere with electrons embedded in it.
• An atom as a whole is electrically neutral because the negative and positive charges are equal in magnitude.

• This model, shown above, resembles a plum pudding. So, it is also called the plum pudding model.

Therefore, option B is correct. Thomson's atomic model is also called the plum pudding model.
