• A. An atom consists of a positively charged sphere and electrons are embedded in it.
• B. The negative and positive charges are equal in magnitude.
• C. An atom consists of a positively charged sphere and neutrons are embedded in it.
• D. An atom consists of a negatively charged sphere and neutrons are embedded in it.

Answer 1

Answer: (A), (B)

The correct options are
A

An atom consists of a positively charged sphere and electrons are embedded in it.

B

The negative and positive charges are equal in magnitude.

Postulates of Thomson’s model of an atom are given below.

1) An atom consists of a positively charged sphere and the electrons are embedded in it.

2) The negative and positive charges are equal in magnitude.

From the above two one can say that the atom as a whole is electrically neutral.
