Diese Vorstellung wurde in der Quantenmechanik zugunsten einer diffusen Verteilung der Aufenthaltswahrscheinlichkeit des Elektrons aufgegeben. Das quantenmechanische Atomorbital erstreckt sich für gebundene Elektronen vom <a href="/wiki/Atomkern" title="Atomkern">Atomkern</a> im Zentrum nach außen bis ins Unendliche, wobei die Aufenthaltswahrscheinlichkeit außerhalb weniger 0,1 nm typischerweise sehr klein ist und für größeren Abstand <a href="/wiki/Asymptotisch" class="mw-redirect" title="Asymptotisch">asymptotisch</a> weiter gegen null geht. Der wahrscheinlichste Abstand vom Atomkern ist für das innerste Orbital gleich dem Radius der 1. bohrschen Kreisbahn. </p><p>Anschaulich stellt man ein Orbital gewöhnlich durch die Oberfläche des kleinstmöglichen Volumens dar, in dessen Inneren sich das Elektron mit großer Wahrscheinlichkeit aufhält.
