The major difference is that Allende is depleted in the most volatile elements, like hydrogen, carbon, oxygen, nitrogen, and the noble gases, relative to the Sun.

主要的差别是，相比于太阳，阿连德陨石缺失了大部分的挥发性元素，例如氢、碳、氧、氮和稀有气体。

What do we know about the noble gases?

那我们对惰性气体有哪些了解呢？

And the answer is yes, we know something about the noble gases.

答案是肯定的，我们对惰性气体有所了解。

I left out the noble gases here because they do something a little bit special, and actually, I'm going to give you one last clicker question today to see if you can tell me what you think noble gases do.

我并没有把稀有气体算在里面,因为它们的电子亲和能有点特别，实际上，我将会把这作为今天的,最后一个选择题，来请大家告诉我,你们觉得稀有气体电子亲和能应该是怎样的。

We have elements that are totally inert, and we have examples of this, the noble gases, dominantly inert.

因为那些元素都是惰性的，而且我们可以举出些例子，比如惰性气体，完全是惰性的。

Perhaps the next Nobel prize involving noble gases will be for medicine, not physics.
