How one can establish that the Earth is round? So once again, my goal is In an atomic nucleus, nucleons thus have a net positive charge. But if one ignored all charged particles except for protons and electrons, $N_e=N_p$ would really arise from the neutrality of the Universe, and it is approximately obeyed by the Universe around us, anyway. The atomic number or nuclear charge number (symbol Z) of a chemical element is the charge number of an atomic nucleus.For ordinary nuclei composed of protons and neutrons, this is equal to the proton number (n p) or the number of protons found in the nucleus of every atom of that element. I guess the goal of the exercise was to compute that equivalence. So, assuming the early universe looked more like the interior of a neutron star than what we see today. that means at the beginning of the universe things were likely electrically neutral. X, Y are respectively. And multiplying our second Our goal is to make science relevant and fun for everyone. yes you can add in the half-reactions but you have to make sure you have a balanced reaction. Isotopes are atoms with the same atomic number but different neutron numbers and thus different mass numbers.
