So, if we look on the periodic table, comparing, for example, s to o, if we have s it's below o, what happens to ionization energy as we go down a table?

那么，如果我们看周期表上，比较，比如，硫和氧，硫在氧下面，当我们沿着表向下看的时候,电离能是怎么变化的？

So as we go down we're now adding electrons to further and further away shells, so what we're going to see is that the atomic radius is going to increase as we're going down the periodic table.

当我们向下走时,我们会将电子加在越来越远的壳层上，因此我们将看到原子半径,将随我们沿周期表向下走而增大。

So that's exactly what we see as we go down the right branches.

当我们这样做下去,我们就会看到这些。

And all of those long notes are coming on the downbeat so that's how we start to hear that as a downbeat and that's how we know to make our hand go down at that point so that's one way.

所有的长音都出现在重拍上,这就是我们怎么判断出重拍,如何判断出该什么时候把手往下摆的,所以那是一条途径

Similarly we see as we go down the table, so as we're going from one row to the next row, so, for example, between helium and lithium, we see a drop; the same with neon to sodium, we see a drop here.

同样地，我们来看看沿着周期表往下走，当我们从一行到下一行时，比如，从氦到锂，我们看到了一个下落;,从氖到钠也一样，我们看到这里有个下落。

So this is not even thinking about the other electron shielding, just if we think of the fact, all we need to think about is that the effect of going to a further away n n as we go down the table.

到现在我们甚至还没有考虑,其它电子的屏蔽效果，即使我们要考虑这个因素，我们需要考虑也就是,沿着周期表的某一列往下走，距离会逐渐变远,将起最重要的作用，actually，dominates,这一结果所产生的影响。

If you want candy, sit much closer down, and that way we can film you as well as we go along. Right.

如果你想要糖的话，坐近一点，这样我们就能,更好的进行互动了，好。

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。

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。

So it cuts it down quickly as we go along.

我们把它缩减的非常快。
