Liste der Isotope/Ordnungszahl 31 bis Ordnungszahl 40

Liste der Isotope ist die Übersichtsseite, um komfortabel auf alle Elemente zugreifen zu können. Dort wird auch der Aufbau erklärt und die Legende zur Tabelle ist auch dort zu finden. Zerfallsenergien wurden mit den angegebenen Massen und dem Masse-Energie-Äquivalent von $\textstyle \Delta m=931{,}4940954{\frac {\mathrm {MeV} }{\mathrm {u} }}$ neu berechnet.
