We look at what is correct about Dalton's atomic theory and what was proven incorrect by the later discovery of the subatomic particles the proton, the neutron and the electron. We look at how the discovery of isotopes also proved that Dalton's atomic theory was not fully correct. Image credits John Dalton https://commons.wikimedia.org/wiki/Fi...
