'''[[버클륨]]'''은 [[인공 원소]]로 표준 원자량이 정해져 있지 않고 [[안정 동위 원소]]가 존재하지 않는다. 최초로 발견된 버클륨 동위 원소는 <sup>243</sup>Bk으로, 1949년에 합성하였다. 원자량 235에서 254 사이에 총 20개의 [[방사성 동위 원소]]와 6개의 [[이성질핵]]이 발견되어 있으며, 가장 안정한 동위 원소는 약 1380년의 [[반감기]]를 갖는 <sup>247</sup>Bk이다.

자연에서는 [[우라늄]] 원자의 [[중성자 포획]]에 의해 미량 존재한다.<ref>{{서적 인용|last=Emsley|first=John|title=Nature's Building Blocks: An A-Z Guide to the Elements|edition=New|year=2011|publisher=Oxford University Press|location=New York, NY|isbn=978-0-19-960563-7}}</ref>
