Same sort of subtraction problem, what do we have for the ionization energy of the 2 s electron?
进行类似的减法运算，得到的，2,s，电子的电离能应该是多大呢？
So let's think about the energy required now to remove a 2 s electron, let's say we're removing it from boron plus 1 versus neutral boron.
那么让我们来想一想，拿走一个，2,s，电子所消耗的能量，假设一个是从正一价硼离子中拿走1，另一个是从中性硼原子中拿走。

There’s a radially symmetric blob, and a double-lobed blob with a node in the middle – just like the patterns of electron density that the s and p atomic orbitals give rise to.
右图中的球是围绕碳原子的电子云的图像。 它们分别是径向对称的球和中间有节点的双扁球形状，就像s和p原子轨道给出的电子密度图。
S — we don't have to hybridize it, it already has only one unpaired electron in a 1 s orbital.
s -我们不用杂化它，它已经有而且仅有一个未配对电子在s轨道里。
So, for example, if we needed to figure out the electron configuration for titanium, 4s2 it would just be argon then 4 s 2, 3d2 and then we would fill in the 3 d 2.
所以举个例子,如果我们需要解出钛的电子构型，它会是Ar然后，然后我们填充。
It makes a lot of sense when we look at it energetically, because if we think about a 1 s core electron, that's going to be held really, really tightly to the nucleus.
从能量的观点来看这是非常合理的，因为如果我们考虑一下，1,s，芯电子，它会被原子核束缚得非常非常紧。
We then have the 1 s 2 electron, and what is our third electron going to be?
然后是1s电子，那么第三个电子会是什么呢？是的？
So for example, if you look at the 1 s orbital here, you can see that actually it is lower in the case of the multi-electron atom than it is for the hydrogen atom.
所以举例来说，如果你看到这里的1s轨道，你可以看到实际上，多电子原子情况的。
So, the first again is the 1 s 1 electron.
所以首先又是1s电子。
So if we write the electron configuration you see that this is the electron configuration here, 1s22s22p 1 s 2, 2 s 2, 2 p 6, 3s1 and now we're going into that third shell 3 s 1.
现在我们来到第三层,你们会看到3s1价电子之间的区别，电子构型是，现在我们来到第三层。
For example, for the 2 s, again what you see is that the multi-electron atom, its 2 s orbital is lower in energy than it is for the hydrogen.
举例来说对于2s轨道，在多电子原子，中可以看到，它的2s轨道的能量低于氢原子的。
