'''[[아연]]'''은 자연에서 5가지의 [[안정 동위 원소]](<sup>64</sup>Zn, <sup>66</sup>Zn, <sup>67</sup>Zn, <sup>68</sup>Zn, <sup>70</sup>Zn)가 존재하며, 이들 중 <sup>64</sup>Zn가 48.6%로 가장 흔하게 존재한다. 이 밖에 25종류의 [[방사성 동위 원소]]와 10가지의 [[이성질핵]]이 알려져 있으며, 이들 중 가장 안정한 것은 244.26일의 반감기를 가지는 <sup>65</sup>Zn과 46.5시간의 반감기를 가지는 <sup>72</sup>Zn이다. 이 밖의 방사성 동위 원소들은 모두 반감기가 14시간 미만이며, 대부분은 1초 미만이다.

아연의 표준 원자량은 65.38(2)[[원자량 단위|u]]이다.<ref>[http://www.iupac.org/news/news-detail/article/standard-atomic-weights-revised-1.html Standard Atomic Weights Revised – IUPAC]{{깨진 링크|url=http://www.iupac.org/news/news-detail/article/standard-atomic-weights-revised-1.html }}</ref>
