On the basis of Thomson’s model of an atom, explain how the atom is neutral as a whole.

According to Thomson’s model of the atom, an atom consists of both negatively and positively charged particles. The negatively charged particles are embedded in the positively charged sphere. These negative and positive charges are equal in magnitude. Thus, by counterbalancing each other’s effect, they make an atom neutral.

As per Thomson’s model of the atom, an atom consists both negative and positive charges which are equal in number and magnitude. So, they balance each other as a result of which atom as a whole is electrically neutral.

On the basis of his experiment, Rutherford put forward the nuclear model of an atom, which had the following features:

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. So the atom as a whole is electrically neutral.

On the basis of Thomson’s model of an atom, an atom consists of an electrically positively charged sphere in which negative charges are embedded. The
magnitude of the positive and negative charges are equal and hence, the atom as a
whole is electrically neutral.
