Well, sodium is going to have the same electron configuration as neon.

好吧，钠将具有与氖相同的电子配置。

Well, to think about that you just have to think about their electron configurations.

好吧，要考虑到这一点，您只需要考虑它们的电子配置即可。

So this is the electron configuration, right here, of nitrogen.

这就是氮的电子构型。

Armed with this knowledge you could write out the electron configuration for pretty much any element on the table.

等等。 有了这些知识， 您就可以写出表格中几乎所有元素的电子构型。

For example, the electron configuration for lithium is going to be the same as the electron configuration of helium, of helium.

例如，锂的电子构型将与氦的电子构型相同。

Helium has two Valence electrons, its electron configuration is one S two.

氦有两个价电子，其电子构型为一S二。

That's why iron's reactivity is a little bit at least based on just this superficial electron configuration.

这就是为什么铁的反应性至少是基于这种表面电子结构的原因。

So what is helium's electron configuration?

那么氦的电子排布是怎样的呢？

So now these guys are both happy from an electron configuration point of view.

所以现在从电子配置的角度来看，这些人都很高兴。

Sodium, you lose an electron, now it looks a lot like neon, at least its electron configuration.

钠，你失去了一个电子，现在它看起来很像氖，至少它的电子配置是这样。

So its electron configuration is going to be 1s2.

所以它的电子构型将是 1s2。

But I prefer to think of an incomplete electron configuration as a cacophonous symphony playing in different keys and at different tempos.

但我更愿意将不完整的电子配置视为以不同的键和不同的速度演奏的不和谐的交响曲。

Its electron configuration is one, S1 that one electron is its one Valence electron.

它的电子排布是一个，一个电子就是它的一个价电子的S1。

So the electron configuration for carbon, the first two electrons go into, so, 1s1, 1s2.

所以碳的电子配置，前两个电子进入，所以，1s1，1s2。

So this is the electron configuration for silicon.

这就是硅的电子构型。

Now what we were doing here, this is called an electron configuration.

现在我们在这里做的，这叫做电子构型。

For example, if you look at the electron configuration for, let's say carbon, carbon is going to have the same electron configuration as helium, as helium.

例如，如果您查看碳的电子配置，碳将具有与氦相同的电子配置，如氦。

But if you wanted to visualize the p orbitals-- let's say we're looking at the electron configuration for, let's say, carbon.

但是如果你想可视化 p 轨道——假设我们正在研究碳的电子配置。

These get a little bit more involved because as we already learned that once you're in the fourth period, Let's say we want to do the electron configuration.

这些会涉及更多一点，因为正如我们已经了解到的那样，一旦你进入第四阶段，假设我们想要进行电子配置。

So if we wanted to write the electron configuration for hydrogen, we would write-- so hydrogen, the electron configuration, it's in the first energy shell, at 1s.

所以如果我们想写出氢的电子构型，我们会写——所以氢， 电子构型，它在第一个能量壳层中， 在 1s 处。
