如果在板子上没有电荷，这些液滴就只会由于重力掉下。

If there is no charge on the plate, these droplets will simply fall under gravity.

因为我们没有电荷补偿，我们就可以随意地加上火减少中子。

And since we don't have to charge compensate, we can add or subtract neutrons at liberty.

这些物质微粒与电子相似，但因为没有电荷，它们可以穿透任何物体。

These particles of matter are similar to electrons, but since they have no electric charge, they can pass through anything.

So if we add them all up, there should be no net charge on the molecule, if the molecule is neutral.

因此如果我们把它们都加起来，这个分子上应该没有净电荷，如果这个分子是中性的话。

And if we were to think about which one of these is better, it turns out that it's the same i in terms of formal charges, so that doesn't help us out.

而如果我们要考虑它们中的哪个更好，结果从形式电荷来看,它们之间没有区别，因此这不能帮我们进行判断。
