Diatomic mean it's di atomic, it's made up of two atoms, and homonuclear means that those two are the same atoms.

双原子意味着它是两个原子，它由两个原子组成，同核意味着这两个原子时相同的原子。

I want to point out that the zero energy is defined as when you have a naked proton -- where the electron has popped out -- that's what we've defined as zero energy up to this point when we're talking about single atoms.

我想指出，这里零点能的定义,是当我们只有一个裸露的质子,而没有电子时-,到目前为止对零点能一直采用这样的定义,当我们在讨论单个原子时。

The one problem that we run into is as we go to more and more atoms on the table, as we add on electrons, the Schrodinger equation is going to get more complicated.

我们将会遇到的一个问题,是当我们处理周期表中越来越多的原子时，当我们增加了电子，薛定谔方程,变得愈加复杂。

Soon when we're talking about multi-electron atoms, and I just want to introduce it here, that it is sort of opposing ideas that even though the s is the biggest and it's most likely that the electron's going to be furthest away from the nucleus, that's also the orbital in which the electron can, in fact, penetrate closest.

当我们说多电子原子时，我这里要先介绍一下，这些概念有些相反,虽然ｓ轨道最大,所以电子最可能远离原子核，但它上面的最容易，穿透到离原子核最近。

z So the main idea here is z effective is not z, so don't try to plug one in for the other, they're absolutely different quantities in any case when we're not talking about a 1 electron atom.

所以这里主要的观点是有效的z不同于，所以不要尝试将一个插入到另一个，当我们不在讨论1个电子的原子时,它们在任何情况下是绝对不同的量子数。

So that doesn't make a difference for us when we're talking about neutral atoms, 4s because we would fill up the 4 s first, because that's lower in energy until we fill it, and then we just keep going with the d orbitals.

所以那对我们来说没什么不同,所以当我们讨论中性原子时，因为我们会首先填充，因为在我们填充它之前它的能量都较低，然后我们继续填充d轨道。

But when we get to the multi-electron atoms, we see that actually the p orbitals are higher in energy than the s orbitals.

但是当我们来看多电子原子时，可以看到实际上p轨道的能量,要高于s轨道。

But instead in this chemistry course, I will just tell you the solutions to differential equations. And what we can do is we can start with some initial value of r, and here I write r being ten angstroms. That's a good approximation when we're talking about atoms because that's about the size of and atom.

但在这个课里，我会直接，告诉你们微分方程的解,我们可以给距离r一个初始值,我这里把r取10埃,当我们讨论原子时,这是一个很好的近似,因为原子的尺寸。
