这时有些电子或离子与油滴碰撞而粘附在油滴上。

Some of the electrons or ions then collide with the drops and stick to them.

因此，作为配体的分子或离子有具有作给予用的孤电子对。

Molecules orions which act a ligands should therefore have lone pairs of electrons for donation.

扩散是微小颗粒或离子分散或者从高浓度区域向低浓度区域传递的过程。

Diffusion is the process by which molecules or ions scatter or spread from regions where they are in higher concentrations toward regions where they are in lower concentrations.

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。

So, basically any time we have a really high positive number of electron affinity, it means that that atom or ion really wants to gain another electron, and it will be very stable and happy if it does so.

因此，基本上无论什么时候,只要我们有一个很大的正的电子亲和能，这就意味着这个原子,或离子非常希望得到一个电子，如果它得到了，会变得更稳定更开心。

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。
