It is formed by a process of "self-ionization".
它是由“自身电离”这一过程形成的。
And we can calculate the ionization energy.
我们能够计算电离能。
So let's compare those ionization energies.
那么让我们来比较一下它们的电离能。
That is the strict definition of ionization.
这是离子化的严格定义。
For example, I could look at the ionization of lithium.
例如，我能观察锂的电离。
An atom is stripped of all electrons by ionization.
一个原子由于电离而被剥掉其全部电子。
Yeah. OK. We're looking for the lowest ionization energy.
对，好，我们再找最低的电离能。
So, oftentimes you'll just be asked about ionization energy.
经常你们会被问到关于电离能。
We will never have a case where ionization energy is negative.
我们绝不会见到一个,电离能是负值的情况。
This is called ionization, gas phase species loses an electron.
而这个过程是离子化，气相组分失去一个电子。
So, as we go down a column, we see ionization energy's going to decrease.
总之，当我们沿着列往下走的时候，我们会看到电离能在降低。
As we go down a column, what happens is that the ionization energy decreases.
当我们沿着列向下走的时候，会发现电离能是在降低的。
The ionization energy, of course, is just the negative of the binding energy.
电离能，我们知道也就是,负的结合能。
So, in terms of ionization energy, we would expect to see sulfur in the middle.
因此，按照电离能，我们应该把硫放在中间。
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 if we want to solve for ionization energy, we can just rearrange this equation.
因此，要想解出电离能，我们只需要将这个方程中的项变换一下位置。
So, thinking about ionization energy, which atom would you put in the middle here?
那么，从电离能的角度考虑，大家会把哪个原子放在中间？
The low ionization potentials of the heavier gases also account for their chemistry.
较重的稀有气体具有较低的电离势，这也可以解释它们的化学性质。
We know that binding energy is always negative, ionization energy is always positive.
我们知道结合能，总是负的，电离能总是正的。
A long tendril of colder gas and dust extends many light years into the void from the receding ionization front.
低温气体和尘埃长长的卷须从渐行渐远的电离前沿一直延伸到数光年远的太空。
The first ionization potentials are as follows: He, 24.6; Ne, 21.6; Ar, 15.8; Kr, 14.0; Xe, 12.1; and Rn, 10.7 eV.
稀有气体的第一电离势是这样的：He 24.6; Ne 21.6;Ar 15.8;Kr 14.0;Xe 12.1;Rn 10.7 eV。
Our ionization energy is going to be equal to the incident energy coming in, minus the kinetic energy of the electron.
我们的电离能将等于，入射能量，减去电子的动能。
If something has a high ionization energy, it means that it really, really, really does not want to give up an electron.
如果某个东西有很高的电离能，这意味着它非常非常，非常不愿意失去一个电子。
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。
