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。
So specifically, what we're asking here is as we go across the periodic table, we want to consider which has the smaller ionization energy.
具体地说，我们这里要问的是，从周期表来看，你认为，哪一个元素的电离能更低。
So, what we can do instead of talking about the ionization energy, z because that's one of our known quantities, so that we can find z effective.
我们做的事可以代替讨论电离能，因为那是我们知道的量子数之一，那是我们可以解出有效的，如果我们重新排列这个方程。

研究了钠、铝对不同电离能和激发能的分析谱线的干扰效应。
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。
So, second ionization energy simply means you've already taken one electron out, now how much energy does it take for you to take a second electron out.
第二电离能简单地说就是，在你已经拿走一个电子以后，再拿走第二个电子，所需要消耗的能量。
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？
