And so, each hydrogen has access to each electron, and now we have a satisfied system.
每个氢原子都有两个电子，这是一个令人满意的体系。
-
If we want to talk about two hydrogen atoms, then we just need to double that, so that's going to be negative 2 6 2 4 kilojoules per mole that we're talking about in terms of a single hydrogen atom.
而要讨论两个氢原子，我们只需要把它乘以二，因此应该是负的，2624，千焦每摩尔,这就是单个的氢原子的情况。

This is the diagram taken right from your text, there are the two electrodes coming in and this is atomic hydrogen in the gas tube.
这是从教科书上复制下来的图表，这里有两个电极进来,这是气体管中的氢原子。
-
So, we see that the two h atoms separate have a certain energy that's lower than when the electron's not with the atom.
那么，我们看到两个分开的氢原子所具有的能量,比原子中没有电子时更低。
-
We don't have two different species of hydrogen here, so the electrons are perfectly shared.
我们没有两个不同源的氢原子，所以电子很好的而得到了平分。
-
Essentially it would only allow for us to bond to two hydrogen atoms.
本质上，它只能允许我们,和两个氢原子成键。
-
So, if we talk about dissociating h 2, we're going from the h 2 molecule, and breaking this bond right in half, so we now have two individual hydrogen atoms here.
那么，如果我们讨论的是离解氢分子，我们将从氢分子开始，使这个键断裂，一分为二，那么就得到了两个分开的氢原子。
-
So there's one electron in each hydrogen atom.
所以每个氢原子中有两个电子。
-
We've got an electron from each of the hydrogens.
然后我们从氢原子那得到了两个电子。
-
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。
-
Now here are these two isolated hydrogen atoms.
现在这是两个分别独立的氢原子。
-
Both hydrogens are going to share equally.
两个氢原子将平分能量。
-
So we can have our two hydrogen atoms come in here, and what we will find is - now that we have all of our orbitals filled up -- so thinking about what this angle is here, would you expect it to be less than or greater than what we saw for ammonia before?
我们在这里有两个氢原子，我们会发现,现在我们所有的轨道都填满了-,考虑一下这里的角度，你们觉得它比在氨中看到的,要大还是要小？
-
So, if we look at this graph where what we're charting is the internuclear distance, so the distance between these two hydrogen atoms, as a function of energy, -- what we are going to see is a curve that looks like this -- this is the general curve that you'll see for any covalent bond, and we'll explain where that comes from in a minute.
因此，如果我们来看一看这幅曲线图,这里我们画的横坐标是核间距，也就是这两个氢原子之间的距离，纵坐标是能量，我们看到的这是能量关于核间距的曲线-,这是一条普遍的曲线，在研究任何共价键时你都会遇到，我们马上就会解释一下它是怎么来的。
-
So you can see here in this slide we have the atomic orbitals for the two hydrogen atoms, each of them have one electron in them, hydrogen has one electron in a 1 s orbital.
从这个幻灯片你们可以看到我们,有这两个氢原子的原子轨道，每个上面有个电子，氢原子上面有一个电子在1s轨道上。
