Webb30 maj 2024 · Both radon and oganesson consist only of radioactive isotopes. Noble Gas Properties The noble gases are relatively nonreactive. In fact, they are the least reactive elements on the periodic table. This is because they have a complete valence shell. They have little tendency to gain or lose electrons. Det finns inga grundämnen med ett atomnummer över 82 (efter bly) som har stabila isotoper. Kärnans stabilitet minskar i stort sett då atomnumret stiger. Alla isotoper med ett atomnummer över 101 sönderfaller radioaktivt med en halveringstid under en dag. På grund av anledningar man ännu inte har förstått helt så finns det en viss ökning i kärnstabiliteten kring atomnummer 110–114, …
