Expert Answer

The charged particles are the particles which are either neutral or which carries positive or negative charge on them. It may be either a subatomic particle or an ion.

The negatively charged subatomic particles are the electrons and they carry the negative charge of ?1.6×10?19 C. These are the fundamental charges and the basic constituents of the atoms and all the particles and elements exist in nature. The electrons can be made by the combination of other particles like quarks or fermions or bosons or leptons. Till date no electron is broken into any of these charges and hence it is only in theory that the electron could be made up of these particles.
The positively charged sub atomic particles are protons and it carries a positive charge of +1.6×10?19 C. These are found in the nucleus of the atom along with the neutrons. They tend to balance the charges in the atom and because of their presence the element of the periodic table are electrically neutral. The number of protons in an atom is known as Atomic Number. The protons are 10,000 times heavier than the electrons and along with the neutrons are the responsible for the weight of the atom. The weight of a proton is 1.67×10?27 kg.
