So what that means is that's how much energy we would have to put into a hydrogen molecule in order to get it to split apart into its two atoms.

它的意义,就是我们需要向一个氢分子中注入这么大的能量,才能将它分解成两个独立的原子。

So if we can figure out the binding energy, we can also figure out how much energy we have to put into our atom in order to a eject or ionize an electron.

所以如果我们可以计算出结合能，我们也可以计算出,我们需要注入多少能量到原子中,去逐出或电离一个电子。

How did we put our gene fragments into this plasmid DNA in order to make multiple copies of it, or to clone the gene?

如何把基因片段整合到质粒DNA上,来获得大量拷贝,或者说来克隆基因呢

This means in order to do that we actually have to put 7 kilojoules per mole of energy into the reaction to make it happen.

这意味为了完成上面的反应,我们不得不往里面注入,7，千焦每摩尔的能量。

putting all those things together, if you looked at this question again we'd get 100% on it, 0 9 that our only option here is 0. 9, and that it's not the negative, it's the positive version, because we're talking about how much energy we have to put into the system in order to eject an electron.

把这些放在一起，你们再看一下题目,大家100%都能选对，我们唯一的选择就是这个，它不是负数，它是正的，因为我们说的，是要,把电子激发出来,需要提供的能量。

Remember, because that 1 s orbital is all the way down in terms of if we're thinking about an energy diagram, we're all the way down here, so we have a huge amount of energy we have to put into the system in order to eject an electron.

还记得吧，因为1，s，轨道在能量示意图里,是在最底部的，我们要一直到最下面，所以我们要向这个系统注入非常大的能量,才能打出一个电子。
