the noble gases

基本解释

What do we know about the noble gases?
那我们对惰性气体有哪些了解呢？
In other words, the noble gases of the atmosphere are isotopically heavier than those of the sun.
换句话说，这些来自大气的惰性气体同位素率相较那些来自太阳的气体更加重。
In all of the known chemical compounds of the noble gases, the noble-gas atom has a net positive charge.
在为人所知的所有稀有气体化合物中，稀有气体原子具有净正电荷。

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。
