Ernest Rutherford (August 30, 1871 - October 19, 1937), also in 1911 had discovered the existence of particles of positively charged protons. He said nucleus consists of protons in it.
Previously scientists thought that the atom must contain a type of small particles other positively charged to offset the negative charge on the electron so that the whole atom is neutral.
Rutherford performed his most famous work after receiving the Nobel prize in 1908. Along with his assistant, Hans Geiger and Ernest Marsden in 1909, he carried out the Geiger–Marsden experiment, which demonstrated the nuclear nature of atoms by deflecting alpha particles passing through a thin gold foil. Because it is unusually ductile, gold can be made into a foil which is
