    The subatomic particles mentioned in daltons atomic model are Protons, Electrons and Neutrons.

    1. Proton :Proton are positively charged subatomic particles.
      Mass of a proton is 1.6727 x 10-24 g.
      For ease of calculations,
      we use amu (Atomic Mass Unit) [ 1 amu = 1.6605 x 10-24 g]
      So, the mass of a proton in amu is 1.007316.
    2. Neutron : Neutrons are particles with zero effective charge i.e neither positive nor negative.
      Mass of a neutron is 1.6750 x 10-24 g which is 1.008701 amu.
    3. Electron : An electron is the negatively charged subatomic particle.
      Mass of an electron is 9.110 x 10-28 g which is 0.000549 amu.
