Kimyoviy elementlarning barqaror izotoplari
Jadvalda kimyoviy elementlarning barqaror izotoplari hamda, Yer yoshiga nisbatan juda katta yarim yemirilish davriga ega bo‘lgan tabiiy radioaktiv izotoplar haqidagi asosiy ma'lumotlar keltirilgan. radioaktiv izotoplar yarim yemirilish davri juda katta bo‘lganligi uchun, ular ham tabiiy barqaror izotoplar turkumiga kiritildi. Jadvalning to‘rtinchi ustunidagi izotop formulasi yonidagi qavs ichida radioaktiv tabiiy izotopning yarom yemirilish davri ko‘rsatilgan.
