For simplicity, let the plasma have only two species: ions and electron; extension to more species is trivial.

为简单起见，假定等离子体只有两种：离子和电子，推广到更多种是不难的。

Hydrogen (H2) at the next catalyst separated into hydrogen ions (h) and electron, hydrogen ions through the solid electrolyte escape, so its concentration can be detected.

氢气(H 2)在催化剂的作用下分离成氢离子(H)和电子，氢离子穿过固体电解质逸出，因此可以检测出其浓度。

Those ions eventually recapture an electron and return to normal.

这些离子最终将重新捕获一个电子而回到正常状态。

But we'll go over that, particularly some exceptions, when we're filling in electron configurations, and how we would go about doing that for positive ions, which follow a little bit of a different procedure.

但是我们将会重温它们，特别是一个特例，当我们填充一个电子构型，而且我们会如何着手,处理阳离子，它遵从一些别的不同的过程。

The positive ions are electron deficient, and these are known as cations.

正离子是缺少电子的，这些就是正离子。

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。
