The first thing we need to do is write the electron configuration for the atom itself, and then we need to take an electron away. 首先我们要做的是,写出原子的电子排布,然后,我们再拿走一个电子。
So, that's actually the electron configuration we have when we're talking about copper and some other exceptions in the periodic table that you're going to be looking at. 因此,这才是铜原子真正的电子排布,而且我们在元素周期表中,会看到与铜原子类似的,其他例外的情况。
So let's do this considering, for example, what it would look like if we were to write out the electron configuration for oxygen where z is going to be equal to8. 我们来做这个考虑,举例来说,如果我们写出,有效电荷量为8的氧的电子构型。
So that's a little bit of an introduction into electron configuration. 所以那是一点点关于,电子构型的入门。
And we put up this hypothesis that our observation is that octet stability seems to be an attractive electron configuration. 我们把假设置于我们的观察之上,即8电子稳定体系,似乎是一种吸引人的电子图像。
So we can go ahead and think about, well, are there any other atoms that are going to have the same electron configuration? 那么我们可以开始想一想,好,有没有其它原子,具有相同的电子排布?
But that's an idea of what it actually means to talk about electron configuration. 但那是一个实际了解什么是,电子构型的思路。
First we can do that by knowing the electron configuration, we can write it out just by going up the table here, up the energy levels. 首先我们知道了电子构型,我们可以从,能量最低处开始填。
So let's figure out the bond order for our two molecules here that we figured out the electron configuration for. 让我们看看这里,两个分子的键序是多少。
So let's think about what the valence electron configuration is here. 让我们看看这里的,电子构型是什么样的。
So this is our electron configuration. 这就是电子构型。
The way electrons occupy the orbitals in an atom is called the electron configuration. 在一个原子中,电子占据轨道的方式称为该原子的电子构型。
So let's draw the electron configuration of hydrogen, the molecule, molecular hydrogen. 让我们来画氢原子的,电子构型,分子,氢分子。
So, if we take h2, and we want to draw the electron configuration, it's very short. 如果我们取h2,我们要画电子构型,这很简单。
And we can also write this in an even simpler form, which is what's called electron configuration, and this is just a shorthand notation for these electron wave functions. 而且我们也可以将它,写为一个更简单的形式,它叫做电子构型,这个仅仅是这些电子波函数的。
If we're actually thinking about electron configuration and we look at lithium, sodium and potassium, these all have one valence electron. 让我们来想一想,锂,钠,钾的电子排布,它们都只有一个价电子。
So basically, at the time he was just going on size and then traits, but what we actually know today is that we can also order things in the periodic table by electron configuration. 基本上,在当时他只能通过大小,和特性来进行,但是现在我们已经知道了,我们还可以通过电子排布来对它们进行排序。
In the first case, so here is the electron configuration of neon. 首先,这是氖原子的电子排布。
So this is our valence electron configuration for b2. 这是B2的价电子构型。
Then something that you probably have a lot of experience with is talking about electron configuration and writing out the electron configuration. 然后有一些事情是,你们可能有较多经验,那就是讨论电子构型以及,写出它们。
So it looks like most of you got that the electron configuration that we're writing here is for copper. 看来大多数人,都看出了,这是铜原子的电子排布。
And again, I've written for you, but you can figure out what the electron configuration is just by writing up in this order here. 同样,我已经写出来了,但你们可以把这个写出来,就知道电子轨道构型是什么。
So here's the pneumonic I mentioned for writing the electron configuration and getting those orbital energies in the right order. 这里是我提到的,对于写电子构型,和以正确的顺序得到轨道能量。
So we can write out what the electron configuration is here, and I think that I have already written that out for you in your notes. 我们可以在这里写出电子构型,我觉得我已经在你们,讲义上写出来了。
And I know there's a lot to talk about this competition, but let's just get into listening mode here and talk about how we can figure out what the correct electron configuration is for this ion. 我知道刚才关于这次比赛大家有很多话要聊,但是请大家先转换到听讲的模式,来看看如何才能弄清楚,这个离子正确的电子排布。
So why don't you go ahead and identify the correct electron configuration for carbon, 6 and I'll tell you that z is equal to6 here. 所以你们为什么不开始,而且识别碳的正确的在你们做作业方面,电子构型,我会告诉你有效电荷量是。
Relationship Between Inorganic Material Properties and Electron Configuration 无机材料性能与电子构型关系的探讨
This paper also discusses topics which, are related to the arrangement of extranuclear electrons, such as the energy-level overlap, the disagreement between the sequences of filling of electrons and losing of electrons and the presence of exception to electron configuration for atoms of some elements. 此外,本文还对无机化学教学中有关核外电子排布的一些问题,如能级交错、填充电子顺序与失去电子顺序不一致以及某些元素原子的电子层结构呈现例外等进行探讨。
This paper presents the new X α method applied to compute radius wave function and electron energy characterisitic data of Si electron configuration, and gains the more accurate results. 该文采用80年代后期在我国逐渐开展起来的Xα方法,计算了Si的电子组态径向波函数和电子能量本征值,得到了较精确的结果。
The equilibrium adsorption structures of the TM atoms depend on the valence electron configuration of the metal atoms. 过渡金属原子在碳管上的平衡吸附构型依赖于金属原子的价电子构型。
