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, 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。

The process took advantage of an electric charge differential existing between the polymer, which was positively charged, and the bacteria cells, which carried a net negative charge.

After all this education, the physican will have substantial negative net worth due to all the loans that the schools charge and a heavy opportunity cost of 11-15 years post HS education in which no net money was made.
