WebHet atoommodel van Ernest Rutherford (met een massieve kern en een wolk met elektronen) wordt nog steeds veel gebruikt. Met dit model kunnen we heel dingen verklaren en voorspellen. Door de ontdekking van het neutron door James Chadwick wordt de kern nu niet meer als één massief deeltje beschouwd maar als een kern met protonen en neutronen.

Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure.
