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, 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?

通过查周期表可以看到它就在氧的正下方，因此它们两个都有六个价电子。

By looking at the periodic table it's right underneath oxygen, so those both have 6 valence electrons.
