# Isotopen van titanium

Het chemisch element titanium (Ti), met een atoommassa van 47,867(1) u, bezit 5 stabiele isotopen: $^{46}$Ti, $^{47}$Ti, $^{48}$Ti, $^{49}$Ti en $^{50}$Ti, waarvan $^{48}$Ti het meest abundant is (ongeveer 74%). De overige 21 radio-isotopen zijn onstabiel en hebben een relatief korte halveringstijd (de meeste minder dan een seconde).
De kortstlevende isotoop van titanium is $^{38}$Ti, met een halfwaardetijd van minder dan 120 nanoseconden. De langstlevende is $^{44}$Ti, met een halfwaardetijd van meer dan 60 jaar.
