Question

A) On the basis of Thomson's model of an atom, explain how atom is neutral as a wholie.B) Which sub-atomic particle is present in the nucleus of an atom ?

Answer 1

1)According to Thomson’s model of an atom, an atom is made up of positively charged substance in the form of a sphere. Into this sphere electrons are embedded. The total negative charge of the electrons is equal to the positive charge of sphere, hence atom remains electrically neutral.

2) On the basis of Rutherford's Model Proton is the subatomic particle which resides in the nucleus. While according to the Bohr's Atomic model neutrons and protons are the subatomic particles residing in the nucleus.
