It is formed by a process of "self-ionization".

它是由“自身电离”这一过程形成的。

So let's address this by considering another example, which should clarify what the difference is between these ionization energies.

让我们用另外一个例子来讲一讲这个问题，这应该能够说清楚,各个电离能之间的区别。

The first ionization potentials of the noble gases provide a measure of how firmly the outer electrons are held by the effective nuclear charge.

稀有气体的一阶电离势提供了一个评价的标准，能衡量外层电子被有效核电荷束缚的强度。

So, this one can be tricky because oxygen looks like it's in the middle because of the way it's written, but we need to start by looking at the lowest ionization energy.

这个例子可能有些狡猾,因为氧看起来是在中间的,因为它是这样写的，但是我们需要从寻找最低的电离能开始。
