So, this is first ionization energy, let's think about second ionization energy.

那么，这就是第一电离能，下面让我们来想一想第二电离能。

youdao

So, second ionization energy simply means you've already taken one electron out, now how much energy does it take for you to take a second electron out.

第二电离能简单地说就是，在你已经拿走一个电子以后，再拿走第二个电子，所需要消耗的能量。

youdao

So I've sort of just spread out what we have as the second row here, graphed against the ionization energy.

所以我将第二行的情况，在这里展了，纵坐标是电离能。

youdao

This is the second ionization energy. That is to say the ionization energy of the second most electron.

这是二级电离能，这就是说,电子数第二多的电离能。

We call these first, second, third ionization energies in sequence. This is the first ionization energy.

我们按照顺序把这些叫做一级，二级,三级电离能，这是初级电离能。
