The there subatomic particles include:
1.Electrons: They were discovered by J.J Thomson. Their have a negative charge = -1.9 ×10^-19 coulomb .They have mass equal to about 1/1840 of hydrogen atom.
2.Protons: They were discovered by E. Goldstein. They have a positive charge = 1.9+10^-19 coulomb. They have a mass equal to that of hydrogen atom
3. Neutrons: They were discovered by James Chadwik. They contain no charge i. e. they are neutral. They have mass equal to the mass of hydrogen atom.
