'''[[Magnesium]]''' ('''12Mg''') secara alami terdapat dalam tiga [[isotop]] [[Isotop stabil|stabil]], 24Mg, 25Mg, dan 26Mg. Ada 19 [[Radionuklida|radioisotop]] yang telah ditemukan, mulai dari 18Mg hingga 40Mg. Radioisotop yang berumur paling panjang adalah 28Mg dengan [[waktu paruh]] 20,915 jam. Isotop yang lebih ringan sebagian besar meluruh menjadi [[isotop natrium]] sedangkan isotop yang lebih berat meluruh menjadi [[isotop aluminium]]. Radioisotop yang berumur paling pendek adalah 19Mg [[Garis tetesan nuklir#Garis tetesan proton|yang tidak terikat proton]] dengan waktu paruh 5 [[Piko-|piko]]detik, meskipun waktu paruh 18Mg yang sama-sama tidak terikat belum terukur.
