And if you come and ask a question that you could have easily answered by doing the reading, coming to lecture, or using Google, they're going to have less patience.

所以如果你过来仅仅是问一个,你能很轻松的,通过阅读、上课、或者，在谷歌上搜索就能得到答案的问题，他们会失去耐心的。

So when we talk about formal charge, basically formal charge is the measure of the extent to which an individual atom within your molecule has either gained or lost an electron.

说到形式电荷，基本上形式电荷就是,单个原子在形成分子之后,是得到了电子还是失去了电子的一种量度。

So, for example, in an electrochemical cell, it would be possible to take the sodium ion, give back its electron, and convert it into a metallic sodium, take the chloride ion, remove its electron, and restore chlorine gas.

所以，例如一个电化学的电池，它可能带有钠离子，让它得到电子，把它变成金属钠，得到氯离子，让它失去电子，作为氯气储存。

So we have four choices in terms of initial and final energy levels, and also what it means - in terms of the electron -- whether it's gaining energy or whether it's going to be emitting energy?

我们有这四个选项,各有不同的初始能量和末能量,它都是按照电子来说的,不管是失去能量还是得到能量？
