WebJul 27, 2015 · How was the nucleus of an atom discovered? By means of the classic gold foil experiment of Marsden, Rutherford, and Geiger, 1909, at the University of … History The nucleus was discovered in 1911, as a result of Ernest Rutherford's efforts to test Thomson's "plum pudding model" of the atom. The electron had already been discovered by J.J. Thomson. Knowing that atoms are electrically neutral, J.J.Thomson postulated that there must be a positive charge as well. In his … See more The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment. After the discovery … See more Nuclei are bound together by the residual strong force (nuclear force). The residual strong force is a minor residuum of the strong interaction which … See more Although the standard model of physics is widely believed to completely describe the composition and behavior of the nucleus, generating … See more • The Nucleus – a chapter from an online textbook • The LIVEChart of Nuclides – IAEA in Java or HTML • Article on the "nuclear shell model", giving nuclear shell filling for the various elements. Accessed September 16, 2009. See more Protons and neutrons are fermions, with different values of the strong isospin quantum number, so two protons and two neutrons can share the same space wave function since they are not identical quantum entities. They are sometimes viewed as two … See more The effective absolute limit of the range of the nuclear force (also known as residual strong force) is represented by halo nuclei such as lithium-11 or boron-14, in which dineutrons, or other collections of neutrons, orbit at distances of about 10 fm (roughly similar to … See more • Giant resonance • List of particles • James Rainwater, modelled non-spherical nuclei • Nuclear medicine • Radioactivity See more

WebLike Thomson’s discovery of the electron, the discovery of radioactivity in uranium by French physicist Henri Becquerel in 1896 forced scientists to radically change their ideas about atomic structure. Radioactivity demonstrated that the atom was neither indivisible nor immutable. Instead of serving merely as an inert matrix for electrons, the atom could … ntdp boys volleyball
