Isotopen van tin
Tin (Sn), met een atoommassa van 114,818(3) u, bezit 10 stabiele isotopen: 112Sn, 114Sn, 115Sn, 116Sn, 117Sn, 118Sn, 119Sn, 120Sn, 122Sn en 124Sn, waarvan 120Sn het meest abundant is (ongeveer 32,5%). De overige 29 radio-isotopen zijn onstabiel en hebben een relatief korte halveringstijd (de meesten minder dan een seconde). Tin is het element met het hoogste aantal stabiele isotopen. Dit is te wijten aan het feit dat 50 een magisch aantal protonen is.
De kortstlevende isotoop van tin is 99Sn, met een halfwaardetijd van ongeveer 5 milliseconden. De langstlevende is 126Sn, met een halfwaardetijd van 230.000 jaar.
