Question

Which of the following is/are true as per Thomson's model of atom?

• A. An atom is not electrically neutral.
• B. An atom is a positively charged sphere with electrons embedded in it.
  
• C. Negative and positive charges in the atom are equal in magnitude.
• D. None of the above

Answer 1

Answer: (B), (C)

An atom is a positively charged sphere with electrons embedded in it.
Negative and positive charges in the atom are equal in magnitude.

Thomson's model of atom states that:

1. An atom consists of a positively charged sphere with electrons embedded in it.
2. Total positive and negative charges in the atom are equal in magnitude. So, atom is electrically neutral.
