The nucleus contains negatively charged particles (electrons) thereby making it to be neutral
Explanation:
An atom contains a centrally placed nucleus containing protons and neutrons while the electrons revolve around the nucleus.
The protons are positively charged while the neutrons has no charge. The electrons are negatively charged.
In the model given above, the centrally placed nucleus has negatively charge particles together with the positive charge particles thereby making it to be neutral. This is not acceptable as the nucleus of an atom is always positively charged.
The correct model of the atom should only have positive nucleus because the neutrons have no charge while negatively charged electrons revolve around.
