WebTrue The nucleus of an atom contains only neutrons True False The number of nucleons present in the nucleus is equal to the number of electrons present outside the nucleus. False The nucleus accounts for almost all the volume of an atom. False The nucleus accounts for almost all the mass of an atom. The largest known completely stable nucleus (i.e. stable to alpha, beta, and gamma decay) is lead-208 which contains a total of 208 nucleons (126 neutrons and 82 protons). Nuclei larger than this maximum are unstable and tend to be increasingly short-lived with larger numbers of nucleons. Meer weergeven 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 … Meer weergeven Protons and neutrons are fermions, with different values of the strong isospin quantum number, so two protons and two neutrons … Meer weergeven The effective absolute limit of the range of the nuclear force (also known as residual strong force) is represented by halo nuclei such as Meer weergeven • Giant resonance • List of particles • James Rainwater, modelled non-spherical nuclei • Nuclear medicine Meer weergeven 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.
