So we haven't gotten to molecules yet, we're just talking about single atoms or single ions, but what's nice is just talking about this very straightforward principle of atomic radius.

我们还没有开始讲分子，我们仍然只是在讨论单个原子或离子，但它的好处在于可以讨论,这个关于原子半径的非常简单直接的原理。

Let's move on to the last topic in terms of this first exam, which is thinking about the idea of isoelectronic atoms, or isoelectronic ions. And isoelectronic is very straightforward, it just means having the same electron configuration.

下面我们继续讲第一次考试的最后一个主题，也就是等电子原子，或等电子离子的概念，“等电子的“是非常直接的表达，它的意思就是具有相同电子排布的。

That's a very large number, it's all relative, so you don't necessarily know it's large without me telling you or giving you other ions to compare to, but chlorine does have a very large affinity, meaning it's really likes getting an electron and becoming a chlorine ion.

这是个非常大的数值，这种数值都是相对的，因此你不一定能知道这是非常大的,除非我告诉你或给你另外离子数值作为参考，但是氯确实有很高的电子亲和能，这意味着它非常乐意得到一个电子,而变成一个氯离子。
