Answer» Atomic nucleus was discovered in 1911 by Ernest Rutherford Explanation:Discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment. After the discovery of the neutron in 1932, models for a nucleus composed of protons and neutrons were quickly DEVELOPED by DMITRI Ivanenko[1] and WERNER Heisenberg.[2][3][4][5][6] An atom is composed of a positively-charged nucleus, with a cloud of negatively-charged electrons surrounding it, bound together by electrostatic force. Almost all of the mass of an atom is located in the nucleus, with a very small CONTRIBUTION from the electron cloud. Protons and neutrons are bound together to form a nucleus by the nuclear force. |
