Изотопи на скандиумот

Природно настанатиот скандиум (21 Sc) е составен од еден стабилен изотоп, 45Sc. Карактеризирани се 27 радиоизотопи, од кои најстабилни се 46 Sc со полураспад од 83,8 дена, 47Sc со полураспад од 3,35 дена и 48Sc со полураспад од 43,7 часа и 44Sc со полураспад од 39 часа. Сите преостанати изотопи имаат полураспад кој е помал од четири часа, а повеќето од нив имаат полураспад помал од две минути, а најмалку стабилен е неврзаниот протон 39Sc со полураспад пократок од 300 наносекунди. Овој елемент има и 13 мета состојби а анјстабилен е најстабилна 44m2Sc (t1/2 58,6 ж).

Изотопите на скандиум се движат од 37Sc до 62Sc. Примарниот режим на распаѓање на маси пониски од единствениот стабилен изотоп, 45Sc, е бета-плус или електронски распад, а примарниот режим на маси над него е бета-минус. Примарните распадни производи при атомска тежина под 45Sc се изотопи на калциумот и примарни производи од поголема атомска тежина се изотопи на титанот.
