丰度分子式：CAS号：性质：即元素的丰度(abundance of element)，指化学元素在一定自然系统中的平均含量，如宇宙丰度、地球丰度、地壳丰度、某区域丰度或某类岩石的丰度等，表示一定空间或类别的地球化学系统中元素的平均含量。丰度有三种不同单位的表示方法。以重量单位表示的称为重量丰度，丰度较高的常量元素一般用重量百分数(wt％或10-2)表示，微量元素多采用百万分数(10-6,g/t)，少数超微量元素用十亿分数(10-9)表示；以原子单位表示的称为原子丰度，为某元素原子数占全部元素总原子数的份额，一般原子百分数(原子％)表示；以相对原子数单位表示的称为相对丰度，是以某一元素的原子数为基准表示的相对原子数，通常取分布较广的硅元素的原子数为106为基准。上述三种不同单位元素丰度中，重量丰度是常用表示方法，也是最基本的丰度数据，它由各类样品测试数据统计计算获得；其他二种丰度可以通过重量丰度换算得到。
