The table of elements at left was constructed from analysis of the solar spectrum, which comes from the photosphere and chromosphere of the Sun. But it is thought to be representative of the entire Sun with the exception of the solar core because of the degree of mixing which takes place between the layers of the Sun's interior.

左边的元素表是通过对太阳光谱的分析而构建的,该光谱来自太阳的光球层和色球层。但由于太阳内部各层之间存在一定程度的混合,因此该表被认为可以代表整个太阳,除外核区域。

About 67 elements have been detected in the solar spectrum.

已检测到约67种元素存在于太阳光谱中。
