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 why don」t you go ahead and identify the correct electron configuration for carbon, 6 and i「ll tell you that z is equal to 6 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。
so let」s think about what this valence electron configuration is for c 2.
让我们来看一下c2的,价电子构型是怎么样的。
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。
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, 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。
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。
so here we「re talking about v plus 1, so if we were to write it just for the neutral electron itself, we would find that the electron configuration is argon, that」s the filled shell in front of it.
这里我们要分析的是正一价的钒离子,因此,我们先写出中性原子的电子排布,可以发现,其原子实是氩原子的电子排布,这些壳层已经被占满了。
so this is our valence electron configuration for b 2.
这是b2的价电子构型。
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。
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 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。
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, selenium 2 minus is what「s going to be isoelectronic, because if you add two electrons to selenium, you」ll get the same electron configuration that you have for krypton here.
负二价的硒离子将是等电子的,因为如果你给硒原子加上两个电子,你会得到,和氪原子相同的电子排布。
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。
s 2 2 s 2 2 p 6 this has the electron configuration of 1 s 2, 2 s 2, and 2 p 6.
它的电子排布是。
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。
