- Iron has four naturally occurring isotopes: 54 Fe, 56 Fe, 57 Fe, and 58 Fe12. 56 Fe is the most abundant, making up 91.754% of naturally occurring iron1. 57 Fe and 58 Fe are present in smaller amounts, at 2.119% and 0.286%, respectively1. 54 Fe is also present, but in even smaller amounts, at 5.845%1. There are also 24 known radioactive isotopes of iron, the most stable of which are 60 Fe and 55 Fe1.了解详细信息:✕以上信息汇总借助人工智能技术,若访问原文请查看了解详细信息。
