And specifically, when we talk about ionization energy, it's assumed that what we mean is actually the first ionization energy.
特别地,当我们讨论电离能的时候,我们默认,这指的是第一电离能。
Well, if we look on the chart, the first ionization energy is what is reported in your Periodic Table.
如果我们查阅图表,一级电离能,已经在元素周期表上标示了。
So, if we want to think about what the first ionization energy is of boron, what you want to do is write out the electron configuration, because then you can think about where it is that the electron's coming out of.
如果我们要考虑,硼的第一电离能,你首先要做的是写出它的电子排布,因为在这之后,你才能知道拿走的是哪里的电子。
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。
So, in a first blush, you might say, well, why don't we just take the first ionization energy?
当你在这个问题上第一次陷入尴尬境地的时候,你可能会说,我们为什么不取第一个电离能呢?
Whenever you hear the term ionization energy, make sure you keep in mind that unless we say otherwise, we're talking about that first ionization energy.
但无论什么时候你听到电离能这个词,一定要记得,除非特别说明,我们都是在说第一电离能。
If you flip the Periodic Table over you will have the ionization energy of sodium, first ionization energy, 5eV and it is about 5 eV which, when you convert, 496kJ/mol is a whopping 496 kilojoules per mole.
如果浏览周期表,你可以得到钠的离子化能,第一电离能,大约,当你转换的时候,是巨大的。
The first ionization energy of lithium is about 5.4 electron volts per atom.
锂的一级电离能,大约是每原子5。4电子伏。
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。
So, let's think about kind of differentiating, however, between first ionization energy or just ionization energy, and other types such as second or third ionization energy, and let's take boron as an example here.
那么,让我们来区分一下第一电离能,也就是电离能与其他类型的电离能,比如第二,第三电离能,我们以硼为例。
What we've learned so far is as a first approximation, what we want to do is put the atom with the lowest ionization energy in the middle here.
我们之前所学的可以作为第一近似,我们要做的是把电离能,最低的原子放在中间。
