So in the case of boron here, what we're starting with is the ion, and now we're going to pull one more electron out.

那么在硼的情况下，我们应该从这个离子开始，现在我们要再拿走一个电子。

The best suggestion is just to write it out completely for the neutral atom, and then you want to take an electron out of the highest orbital.

最好的办法是先写出它所对应,中性原子，然后再从,能量最高的轨道上拿走一个电子。

Now this is a good place to start, because we are very familiar with ionization energy, we've been talking about it it's that minimum energy required to remove an electron from an atom.

现在这是一个开始下面内容的好地方，因为我们已经很熟悉电离能了，我们从很久以前就一直在讨论,它是从一个原子中,拿走一个电子所需要消耗的最低能量。

Will it be if you take a 3 s electron from neutral silicone, if you take a 3 p electron from the neutral atom, or if you take a 3 p from the ion?

是从中性硅原子中拿走一个，3，s，电子呢，还是从中性硅原子中拿走一个，3，p，电子呢，又或者是从硅离子中拿走一个，3，p，电子呢？
