WebDiagram of the nuclear composition and electron configuration of an atom of promethium-147 (atomic number: 61), the most common isotope of this element. The nucleus consists of 61 protons (red) and 86 neutrons (blue). 61 electrons (green) bind to the nucleus, successively occupying available electron shells (rings). WebOxygen contains 8 protons, 8 neutrons and 8 electrons. Hence, for D 2 O Number of electrons =2+8=10 Number of protons =10 Molecular mass of D 2 O =4+16=20 hence, Number of neutrons = Molecular mass - number of protons = …
