Where is the center of net negative charge in this molecule?

分子的负电荷，中心在哪？

The effect of this would be to educe the net negative charge and thus lower the repulsive force seen in Figure 1.

这种方法会减少减少净负电荷，从而降低颗粒间的排斥力，如图1所示。

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。

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。

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。

youdao

When a suBstance has no net electrical charge, the total numBers of positive and negative charges within it must just Be equal.

当物质没有净电荷时，它内部的正负电荷总数必定正好相等。

youdao

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。
