Web13 mei 2016 · If the ions derived from different atoms are isoelectronic species, then they all have same number of electrons in their electronic shells and will have got same electronic configuration but their nuclear charge will differ because of their difference in number of protons in the nucleus. WebA neutral sodium atom, Na, loses one electron to form a cation, Na ^+ +. Image credit: Introduction to Chemistry: General, Organic, and Biological, CC BY-NC-SA 3.0 In the diagram above, we see a neutral atom of sodium, Na, losing an electron. The result is that the sodium ion, Na ^+ +, has 11 protons, but only 10 electrons.
