They examined fluids seeping out of fractures in a mine and found particular isotopes of the noble gas xenon.

他们查看从矿井裂缝中渗出的液体，从中发现了惰性气体氙的特殊同位素。

The noble gases, that's the other name for the group, 18 elements, noble gases.

惰性气体，这是该族的另一个名称，18 种元素，惰性气体。

They're all envious of the noble gases, because the noble gases have eight electrons in their outer shell.

他们都羡慕惰性气体，因为惰性气体的外壳里有八个电子。

Then finally you get to kind of your atomic nirvana in the noble gases here.

然后你终于可以在这里的惰性气体中实现你的原子必杀技。

Group 18 solids meanwhile are the solid phase materials of the noble gases Group 18 on the periodic table.

18族固体同时是元素周期表中第18族惰性气体的固相材料。

Finally, he left clues that led directly to the discovery of the group of elements known as the noble gases, some of which are so elusive that the last of them wasn't found until 1962.

最后，他还留下线索，直接导致一组名叫惰性气体的元素的发现。其中有几种是极难获得的，最后一种直到1962年才被发现。

Once again the reason why it's out here with the noble gases is because it's very stable and very inert like the noble gases that's why we now use those helium for balloons instead of hydrogen.

再一次，它与惰性气体一起出现在这里的原因是因为它像惰性气体一样非常稳定和非常惰性，这就是为什么我们现在将这些氦气而不是氢气用于气球。

Now let's think about helium and helium's an interesting character because all of the rest of the noble gases have eight Valence electrons which makes them very stable but helium only has two Valence electrons.

现在让我们考虑一下氦，氦是一个有趣的特性，因为所有其他惰性气体都有八个价电子，这使得它们非常稳定，但氦只有两个价电子。

These are going to be the most electronegative, Sometimes we don't think as much about the noble gases because they aren't, they aren't really that reactive, they don't even form covalent bond, because they're just happy.

这些将是最具电负性的，有时我们对惰性气体考虑得不多，因为它们不是，它们并不是那么活泼，它们甚至不形成共价键，因为它们只是快乐.
