WebbBased on the number of \alpha α particles deflected in his experiment, Rutherford calculated that the nucleus took up a tiny fraction of the volume of the atom. The nuclear model explained Rutherford's experimental results, but it also raised further questions. For example, what were the electrons doing in the atom? WebbThe proton and neutron are collectively called as (A) deuteron (B) positron (C) meson (D) nucleon Q20. The atomic weight of an element is 39. The number of neutrons in its nucleus is one more than the number of protons. The number of protons, neutrons and electrons respectively in its atom would be
Nuclear Physics 101: What Holds the Nucleus Together?
Webb6 juli 2015 · To give a well-known example, U-238 is a 0+ nucleus, so it appears spherical to all measurements: there is no direction for an asymmetry to point. Np-239 is essentially … Webb13 apr. 2024 · He described it as a positively charged nucleus, comprised of protons and neutrons, surrounded by a negatively charged electron cloud. In the model, electrons orbit the nucleus in atomic shells. The atom is held together by electrostatic forces between the positive nucleus and negative surroundings.
