It doesn't have to put federal bureaucrats in charge of what procedure is covered and what medication is not."

So we could think about comparing the potassium ion to a sodium ion. They have the same charge of plus one.

我们可以想象比较一下钾离子,与钠离子，它们都同样带有正一价的电荷。

So for example, that might have a formal charge of negative 1, because to some extent it has gained that much electron density that it now has a formal charge that's negative.

比如，可能它的形式电荷为负一，因为在一定程度上它得到了这么多的共用电子密度,那么它现在就有了负的形式电荷。

Prime Minister Fischer and President Klaus have yet to decide who will be in charge of this and other events of the E.U.presidency.

The examples we've done so far have been pretty straightforward, so we haven't needed to use formal charge to make this kind of decision.

我们之前做过的例题,都是非常简单直接的，因此我们还不需要,用形式电荷来做这种决定。

The only thing they have to pay on that is a regular interest charge to the IMF as a fee for the conversion of the currency,"

But we could, for example, look at a case where we have several different structures that look pretty good, and the one we want to determine as being the lowest energy structure is the one in which the absolute values of the formal charges are going to be lower, so essentially that they have less charge separation.

但是我们可能，比如，遇到一种情况,有好几个候选的路易斯结构看起来都挺好的，这时候我们就需要,通过比较哪个形式电荷的绝对值更低,来决定哪个结构的能量更低，本质上这个结构中分开的电荷更少。

So, let's say we have an atomic number of 3, 3 that means we have 3 electrons, so we better hope to get our neutral atom that we have a charge of plus 3in the nucleus.

这也是很合理的，因为Z就是原子序数，假设原子序数是，那就有3个电子，那我们就希望,性原子有个带3个正电荷的原子核。
