But, can you see that as you get really close together the negative electronic cloud surrounding the two ions start to sense one another.

然后当你真的让它们,离得很近时,这两个离子周围的负电子云能感应到对方。

So we know what that number would be, it would be negative 424 kilojoules per mole that we see here.

我们知道它的值是多少，它就是我们在这见到过的负，424，千焦每摩尔。

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 other theme that we see throughout the Deuteronomistic material is the negative presentation of the Canaanites.

我们在《申命记》中看到的另一主题是,对迦南人负面的描述。

It could be that in thinking about the nature of the combination we're led to see that in certain ways the combination-- the interaction effects--are negative, are bad ones.

可能在考虑这种组合的本质时,我们看到了再某些方面这种组合-,相互影响，是负面的，是不好的。

And remember again, the binding energy physically is the negative of the ionization energy, and that's actually how you can experimentally check to see if this is actually correct.

电离能的负值，那个事实上是可以,通过实验来验证，它是否是对的,并且它等于负的。

So, let's change our graph where we now have this zero point set as the two individuals hydrogen atoms, and then we see that our h 2 molecule is at the negative of the dissociation energy, or the negative what that bond strength is.

那么让我们把曲线图中的零点能改到,两个分离的氢原子处，那我们就会看到,氢分子就是负的离解能，或者负的键的强度。

If we think of the size of a typical atom, we would say that would be about 10 to the negative 10 meters. So, we can see the diameter of a nucleus is absolutely smaller really concentrating that mass into a very small space.

一个普通细胞的大小，抱歉，我和细胞核搞混了0,如果我们考虑，一个普通原子的大小,这大概是10的负十次方米,所以原子核的直径确实非常小,真的是把质量。

This was my first glance at plum pudding, and I guess you can see that this must be that positive part -- most of the plums are within that, and you can see all these little raisins or plums in here, that would be that negative charge.

我想你们可以，看到着一定是正电部分,大部分的李子,都在这里面，你们也可以看到,这些小的葡萄干或李子，这就是负电荷。

So, in this case, we see that our formal charge is negative on the nitrogen, in this case it's negative on oxygen.

那么，在这种情况下，我们看到氮的形式电荷是负的，而在这种情况下，氧的是负的。

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 we know that we can relate to z effective to the actual energy level of each of those orbitals, and we can do that using this equation here where it's negative z effective squared r h over n squared, we're going to see that again and again.

我们知道我们可以将有效电荷量与,每个轨道的实际能级联系起来，我们可以使用方程去解它,乘以RH除以n的平方,它等于负的有效电荷量的平方,我们将会一次又一次的看到它。
