We'll then take a turn to talking about the periodic table, we'll look at a bunch of periodic trends, including ionization energy, electron affinity, electronegativity and atomic radius.

然后我们再开始讲元素周期表，我们会看到很多周期性规律，比如电离能，电子亲和能，电负性以及原子半径。

So let's turn our attention to a new topic, which is thinking a little bit about the periodic table, and also talking about periodic trends.

我们的新主题上，我们将会讨论一点关于元素周期表的知识，同时也会讲一讲周期性规律。

And there's a lot we can explain by talking about what we see in the periodic table in terms of what different trends are in grouping different elements in different spots within the periodic table.

我们可以解释很多，通过讨论元素，周期表中的内容，按照各种不同的规律，将周期表中不同位置的元素分组归类。
