Web11 de jan. de 2016 · Let's take the simplest example, atomic hydrogen, #H#.In hydrogen nuclei there is ONE fundamental, positively charged nucleon, a NUCLEAR proton (note that in this "nucular" context, protons are different from acidic species, which we often represent as #H^+#.We could represent this species as #""^1H#, and in fact most of the hydrogen … WebIsotopes are atoms that have the same numbers of protons but different numbers of neutrons. An ion is an atom that has gained or lost electrons, so it now has more or fewer electrons than it does protons. So an ion has a negative or positive charge. All atoms are isotopes and if an isotope gains or loses electrons it becomes an ion.
