The correct option is B

False

False.

Now we know that the atom can be divided into its subatomic particles i.e., electrons, protons and neutrons. J.J Thomson gave an atomic model according to which
1. An atom consists of a positively charged sphere with electrons embedded in it.
2. The positive and negative charges are equal in magnitude; hence the atom as a whole is electrically neutral.
