Question

Which of the following are the postulates of Thomson’s model of an atom?

• 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 electrons are embedded in it, the posivite and negative charges are equal in magnitude.
• 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

Thomson proposed that :

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