자연계에 존재하는 [[주석 (원소)|주석]]의 '''안정 동위 원소'''는 10종으로 가장 많이 존재한다. 

인공적으로 만들어진 주석의 동위 원소는 <sup>99</sup>Sn에서 <sup>137</sup>Sn까지 존재한다. 이중 <sup>99</sup>Sn은 인공적으로 만들어진 동위 원소들 중 [[양성자]]의 개수가 [[중성자]]보다 더 많은 동위 원소들 중 가장 무거우며, <sup>100</sup>Sn는 양성자가 중성자와의 개수가 동일한 동위 원소들 가장 무거우며, 이중 마법 수를 가지고 있다.

<sup>121m1</sup>Sn은 들떠 있지만 반감기는 43.9년이나 되어 중간 반감기 핵분열 생성물로 분류되며, 이들 중 가장 낮은 비율로 생성된다.

<sup>126</sup>Sn은 주석의 핵분열 방사성 동위 원소 생성물들 중 반감기가 가장 긴 23만년이며, 태양계 극 초창기에는 많이 존재했었지만 [[반감기]]가 짧아 이른 시기에 사라졌으며, 현재는 [[우라늄]], [[토륨]]의 자발핵분열 생성물로 자연계에 미량 존재하며, [[원자로]]의 [[핵분열]]로 생성된다.
