Hello Soni

Neutrons,Protons and Electrons all are parts of an atom.

Neutron:It is found in the nuclues of every atom other than hydrogen.It is called neutron because it does not have any charge and is neutral.The total number of neutrons in an atom tells about the isotope and also about the physical properties of an atom.

Proton:Protons are also present in the nuclues of an atom but each proton have a positive charge of +1.The total number of protons determines which element the atom belongs to and also tells about the chemical properties of that atom.

Electron:Electrons are located in the volume of atoms around the nuclues and each electron has a negative charge of -1.They are considered to be elementary paricles.
