Why? Bundle of properties: mechanical strength, chemical inertness, ease of fabrication: that's not a unique solution.

为什么，属性的总和：,机械强度，化学惰性，易于制造，那不是独特的解决方法。

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。

Versus looking at, for example, helium or neon or argon, these are all inert gases, inert meaning essentially do not react, those were grouped together in the periodic table.

相反，他发现氦，氖，氩，都是惰性气体，惰性的意思是基本不参与化学反应，因此把它们放在周期表中的同一类里。

So they have to be engineered to be inert so that they can be safely inside a system and there's not every material you could pick would have that property.

缝合线必须是惰性的,以便确保植入人体后的安全性,不是随便哪个材料都能做到这一点

So platina is like a diminutive of silver, but we now know that platinum is far superior to silver It is far more noble. It has a higher melting point, a higher chemical inertness, a fantastic metal.

所以普拉塔就像一个小小的银，但我们现在知道普拉塔比银要好很多,更为珍贵，熔点更高，化学惰性更高，是一种非常不可思议的金属。

I know neon has a higher yet electronegativity, but normally it is inert.

我知道氖有个更高的电子力，但在常态下它是惰性气体。

So, no matter whether or not you write out the full form here, or the noble gas configuration where you write ne first or whatever the 3s1 corresponding noble gas is to the core electrons, we always write out the valence electrons here.

所以无论你是否,写出了完整形式，或者对应于价电子的惰性气体,再一次,我们可以写Ne然后，我们总是可以在这里写出价电子。

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。

And, although you think that nitrogen, I mean, it's an inert gas.

尽管你认为那是氮气，我的意思是，它是一种惰性气体。
