我要说的是，完全相反，正电荷集中在中心,在一个非常非常小的体积内。
-
If the atom is fixed mass, the electron is tiny, It must be the positives have all the mass.

-
So we can do this for any final charge we have, if we have a molecule that has a charge of plus 2, then all of the formal charges should add up to plus 2 and so on.
对于任意净电荷的情况,我们都可以这样做，比如假设我们有一个带两个正电荷的分子，那么所有的形式电荷加起来应该等于正二，等等。

It still has positive charge, and there is nothing saying another chloride could not stick to it.
它仍然具有正电荷，不能说明另外一个氯,不能固定在上面。
-
So, essentially you've got a positive ball which is identical to the size of the atom.
首先你要有一个和原子差不多大小的,带正电荷的球。
-
And so, if we go and we draw this again, if this is the carbon here, hydrogen, hydrogen, hydrogen, hydrogen like this, then this is going to be a little bit plus.
如果我们继续，我们将再次画下这个，如果这儿是碳，氢，氢，氢，氢，就像这样，这里有些正电荷。
-
There is nothing saying that that sodium, its positive charge has not been neutralized.
什么也没有，钠的正电荷没有被中和是。
-
And, it involves a single electron orbiting a positively charged nucleus.
包含了一个单独的电子轨道,一个带正电荷的核。
-
This is a point that's negative, and this is the point that's positive.
这是一个负电荷，这是一个正电荷。
-
He shot alpha particles which have a charge of plus two.

-
And, so we have the positive charge in the center.
正电荷在中心。
-
The center of the delta minus is the center of the molecule.
正电荷中心在分子中心。
-
So where is the center of the delta minus?
正电荷中心在哪？
-
So, shielding happens when you have more than one electron in an atom, and the reason that it's happening is because you're actually canceling out some of that positive charge from the nucleus or that attractive force with a repulsive force between two electrons.
所以当你们在原子中有多于一个电子,屏蔽就会发生，它之所以会发生的原因是,你们实际上抵消了,一些来自原子核的正电荷,或者来自吸引力,在两个电子之间。
-
So, the bulk of the atom is positive.
原子的主体带正电荷。
-
So if we have total +2 and complete shielding -1 where that can actually negate a full positive charge, because remember our nucleus is plus 2, +1 one of the electrons is minus 1, so if it totally blocks it, all we would have left from the nucleus is an effective charge of plus 1.
抵消一个完全的正电荷,因为记住我们的原子核是,其中一个电子是,所以如果它完全挡住了它，我们从原子核中留下的，全部有效电荷就是，所以，在我们的第一个例子中,我们的第一种极端情况。
-
But once in awhile, one of these plus twos comes in almost on axis, and it gets whipped around by the Coulombic repulsive forces.
但是偶尔一个带两个正电荷的粒子,以接近于轴的位置进入，会快速的移动到周围,由于库仑斥力的作用。
-
And so we have a positive charge in the nucleus which is given by the number of protons.
在原子核上,有很多质子聚集而形成的正电荷。
-
It could be hydrogen, it could be helium plus, it could be lithium double plus and so on.
它可能是氢，可能是带一个正电荷的氦，也可能是带两个正电荷的锂，等等。
-
So, this is a positive sphere of custard, and inside are little, negative bits.

-
So, if I've got positive charge uniformly distributed, look at the choice. It's a brilliant experiment.
所以如果按照正电荷是均匀分布的假设来说，就会是这样的，这是一个聪明的实验。
-
So, I've got this tiny volume with, in the case of gold 79 plus of charge, and I've got some electrons out here somewhere, and the vast majority of the atom is nothing.
我认为这个小体积里面，比如金的79个正电荷，电子在外面的某些地方，原子里面大部分是空心的。

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。
-
OK, so all I do is I take into account that I've got all the positive charge, whatever it is, it's a nucleus.
我做的全部是考虑,我得到所有的正电荷，无论是什么，都是一个核。
-
Coulomb's law says the negative will be attracted to the positive, and the atom will collapse.
