So, in order to fill our octet, what we do is put two on the nitrogen and two on the carbon.
因此,为了填满我们的“八隅体“,我们需要将两个放到氮上,将另外两个放到碳上。
So in terms of total numbers that we would need to complete our octets and fill our valence shells, we would need 18 electrons.
因此要填满我们的“八隅体“,排满所有的价壳层,我们总共需要十八个电子。
Right now, with our 50, 80, 100 years, we don't fill our day doing only one kind of activity.
在眼下的有限生命中,我们也没有每天只从事一项活动。
So again you can see as we're filling up our molecular orbitals, we're using the exact same principle we used to fill up atomic orbitals.
当我们填充轨道的时候可以看到,我们用的是和,填充原子轨道一样的原则。
So we have a total of 2, 4, 6, 8, 10 valence electrons, so I'll make sure I count to 10 as we fill up our molecular orbitals here.
我们一共有2,4,6,8,10个价电子,所以我一边填一边要确认,我数到10。
So again, we can fill in our atomic orbitals here, there's going to be two electrons in each of our atomic orbitals.
同样的,我们可以填充原子轨道,每个原子轨道上有两个电子。
So, in order to fill up our shell, what we need is 3 times 8 or 24 electrons.
因此,为了填满所有的壳层,我们需要三乘以八也就是二十四个电子。
Because step five is that we need to fill in our bonding electrons, and we start it with filling in two electrons per bond.
因为第五步要做的是将我们的成键电子填在这,所以我们开始在每个键处填上两个电子。
So to figure out bonding electrons, -- what we take is that number 18, which is our total number of electrons we need to fill valence shells, and we subtract it from our number of valence electrons, which is 10.
那么为了找出成键电子,我们将十八,也就是填满所有价壳层,所需要电子的总个数,减去我们所有的价电子的个数,也就是十。
So we can add three hydrogen atoms here, and fill in our other orbitals right here.
我们可以加三个氢原子到这里,填满其它的轨道。
So what we need to do is fill in those extra bonding electrons into our bonds.
因此我们需要,把这些电子也填到键中。
And all we need to do is go over here now and fill up our octets.
而我们所需要做的就是到这里来,把我们的“八隅体“都填满。
Our step three is to figure out how many bonding electrons that we need, or excuse me, how many total electrons that we need to fill up our octets, so that's just going to be 4 times 8, which is 32.
我们的第三步是判断,我们需要多少个成键电子,不好意思,是我们总共需要多少个电子,才能填满所有“八隅体“,那么这就应该是四乘上八,也就是三十二。
So we'll start to look at molecules and we'll see if we take two atoms and we fill in our molecular orbital and it turns out that they have more anti-bonding orbitals than bonding, that's -- a diatomic molecule we'll never see.
我们要看开始看一看分子,并且我们会发现如果我们,取两个原子并且填入分子轨道,结果是它们的反键轨道,比成键轨道更多,这就是-一个我们不会看到的二元子分子。
So now let's go ahead and fill in our molecular orbitals.
让我们继续填充分子轨道。
And then this means we'll have a total of sigma1s two electrons in our hydrogen molecule, so we can fill both of those into the sigma 1 s orbital, the bonding orbital. We don't have to put anything into the anti-bonding orbital, so that's great.
我们可以把这两个,都填入,轨道里去,成键轨道,我们不需要把什么放到反键轨道里去,这很好。
We fill our day with a mixture of activities.
而是做各种事情。
So, we need to fill our octet for selenium, so 1, 2, 3, 4.So, this is our Lewis structure here, hopefully you can see why it's not linear.
我们要填满硒原子的八配位,所以1,2,3,4。这就是Lewis结构,希望你们能看出来为什么它不是直线型的。
We can fill right up our table just like we did before, but now we have included our 2 p z orbital here.
我们可以像以前一样填充表格,但现在我们包括了2pz轨道。
So carbon has four valence electrons, so if we talk about c 2, again we're going to start filling in our molecular orbitals, and now we're going to have eight electrons to fill into our molecular orbitals.
碳有4个价电子,所以如果我们考虑C2的话,同样,我们开始填分子轨道,现在我们有8个电子,要填入分子轨道。
So we have two electrons in our bonding orbital, but because we use the same rules to fill up molecular orbitals as we do atomic orbitals, so the Pauli exclusion principle tells us we can't have more than two electrons per orbital, so we have to go up to our anti-bonding orbital here.
所以在成键轨道上有两个电子,但因为我们用了和原子轨道时,用的相同的规则,所以Pauli不相容原理告诉我们,一个轨道上不能有两个以上的电子,所以我们需要填充到反键轨道上去。
