Answer : The correct option is,
Particles Charge Location
Proton + inside nucleus
Electron - outside nucleus
Neutron 0 inside nucleus
Explanation :
As we know that an atom is the smallest unit of a matter that consist of three subatomic particles which are electrons, protons and neutrons.
The protons and the neutrons are located inside the nucleus or center of the nucleus where the mass of the an atom is concentrated and the electrons are located around the nucleus.
The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.
From the given table, we conclude that
The particle proton has positive charge and location is inside the nucleus.
The particle electron has negative charge and location is outside the nucleus.
The particle neutrons has no charge and location is inside the nucleus.
