Basic Atomic Structure

(Subatomic Particles)


    Subatomic Particle          Mass        Charge

            Proton                 ~ 1 a.m.u           +1

           Electron               ~ 0 a.m.u.           -1

           Neutron               ~ 1 a.m.u.            0


  a.m.u. = atomic mass unit = 1/12 the mass of a carbon-12 atom
