鋰的同位素

鋰（原子量：6.941(2)）共有10個已知同位素，質量數介於4-13之間，其中有2個是穩定的，其他都具有放射性。天然存在的鋰同位素有2個，分別是6Li和7Li，皆為穩定同位素，其中以7Li占天然鋰的大部分，豐度為92.41%。其他放射性同位素都不出現在自然界中，只有在實驗室製造出來過，且半衰期都極短，非常不穩定。一般来说，盐湖锂矿所含的锂-6比例多低于海洋背景水平，茶卡盐湖的尤其低；Mao-Yong He, Chong-Guang Luo, Hong-Jun Yang, Fan-Cui Kong, Yu-Long Li, Li Deng, Xi-Ying Zhang, Kai-Yuan Yang,
