The mass number 204 – 82 protons = 122 neutrons. You can see my papers of nuclear structure in  my  FUNDAMENTAL PHYSICS CONCEPTS . An atom contains protons (positively-charged particles), electrons (negatively-charged particles), and neutrons (neutrally-charged particles). An element's atomic number is defined by the number of protons it has. e. 20 protons, 20 neutrons, and 22 electrons 7. In the following diagram of Se-82 you see that the 64 nucleons with 32 protons and 32 neutrons from p1n1 to p32n32 have a structure of high symmetry . The paper was also presented at a nuclear conference held at NCSR "Demokritos" (2002). Also the 14 extra neutrons of opposite spins are not shown. Calculate the number of protons, neutrons, and electrons in 210/ Pb4+. The nucleus consists of 34 protons (red) and 46 neutrons (blue). It is of interest to note that the two first extra neutrons like the n35(-1/2) and the n36(+1/2) fill the  two blank positions formed by p33n33 and p34n43 respectively. Su masa es 1/1,837 de la masa de un protón. However, when it is charged, the number of lost or gained electrons is equal to the charge. The atomic number of Se is 34.
