Now you have this situation where you have a droplet that is net negative or perhaps net positive.
现在的情况是那些液滴,可能是净负电,也可能是净正电。
So, when we get really close together, granted, there is a net positive negative charge with a Coulombic force of attraction.
当它们真正离得很近时,假设有一个带正负电的电荷,带有库仑引力。
So, if we think about the second case here where we have c n minus, now we're talking about a molecule with a net charge of negative 1.
那么,如果我们考虑的是第二个例子,也就是氰离子,那么现在我们讨论的是一个净电荷量为负一的分子。
Here is a chart that just shows the positive energies, and you can see the various components, and then the negative energies and the net.
这是展示正能量的表格,你可以看到不同的成分,负能量和总能量。
The molecule is net neutral, but this right end is a little bit more negative and the left end is a little bit more positive.
这分子是电中性的,但右边要带一点负电荷,而左边要带一点正电荷。
So that means if we add up all of the formal charges within the molecule, what we would expect to see is that they sum up to give a net charge of negative 1.
那么这就意味着如果我们把这个分子中,所有的形式电荷加起来,我们应该会看到它们加起来,之后得到的净电荷量为负一。
And there is this separation which is a balance of attractive forces because the chloride is net negative and the sodium is net positive, but both of them, regardless of net charge, have electrons.
这里有一个平衡,引力的平衡,由于氯离子带有负的净电荷,钠离子带有正的净电荷,但是它们两个,没有考虑净电荷,电子。
Where is the center of net negative charge in this molecule?
分子的负电荷,中心在哪?
And the chloride is net negative.
而氯离子带负电。
