Answer :
ElectronsProtonsNeutron
Electrons are Negatively charged particles
Electrons are present in outer shells with in an atom and  revolve around the nucleus in well-defined orbits or discrete orbits
The mass of an electron is about 1/ 2000 times
the mass of an hydrogen atom.
A electron  is represented as 'e-'
Protons are Positively charged particles.
Protons are present in the nucleus of all atoms
Number of protons determines the atomic number of an element
The mass of a proton is taken as one unit and equals to neutron.
A proton is represented as 'p+'
Neutrons do not carry any charge and are neutral.
Neutrons are present in the nucleus of all atoms, except hydrogen
The mass of a neutron is taken as one unit and equals to that of proton.
A neutron is represented as 'n'
