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 what we can actually directly compare is the dissociation energy or the bond strength of nitrogen versus hydrogen.
因此实际上我们可以直接进行比较,对氮分子与氢分子的离解能,或键的强度。
It doesn't go all the way to absolutely 100 percent ammoniazero hydrogen zero nitrogen if they were mixed together with the right ratios.
即使按适当比例混合,也不会出现全部氨气,没有氢气和氮气的情况。
If we take nitrogen, we've got N2, and we've got one, two, three, four, five.
比如说氮,我们得到了氮气,我们有一个,两个,三个,四个,五个。
So, electron promotion does not happen in terms of nitrogen, because it would not increased our number of unpaired electrons.
这里对于氮原子不会有电子激发,因为这不会增加,未配对电子的数目。
We see that the radius is shorter, so that means that the nitrogen-nitrogen bond is going to be shorter.
我们看到这个距离更短,这就意味着,氮与氮之间的键应该更短。
4 6 Just as in nitrogen, we get two, four, six here, but now we have two more electrons.
对于氮,我们有,但是现在我们有两个多的电子。
So this is not going to be a favorable process, we're going to find that the electron affinity is actually a negative 7 kilojoules per mole for nitrogen.
因此这并不是一个容易发生的过程,我们会发现氮的电子亲和能,应该是负的,7,千焦每摩尔。
So, shared electrons are the ones that are shared between the carbon and the nitrogen, so we have 6 shared electrons, and we want to take 1/2 of that.
共用电子是那些在碳和氮之间,被它们共用的电子,那么我们有六个共用电子,然后我们要给它乘上二分之一。
So in terms of nitrogen that starts off with a valence number of 5, again we have 2 lone pair electrons in the nitrogen, and again, we have 6 electrons that are shared.
对于氮来说,我们应该从五个价电子开始,同样,氮也有两个孤对电子,共用电子的个数也一样,是六个。
This is very easy molecule because we know exactly where to put them without even having to think, we only have one option, and we'll make a triple bond between the carbon and the nitrogen.
这个分子非常简单,因为我们知道应该把它们放在哪里,甚至不用去想,我们只有一个选择,我们将在碳与氮之间形成一个三键。
So if we take a look at nitrogen here, what you'll notice is we have thre available for bonding, - and we already have our lone pair -- one of our orbitals is already filled up.
如果我们看一下氮原子,我们注意到我们可以成3个键,我们已经有一个孤对-,其中的一个轨道已经被填满了。
090 We have 1,090 for carbon, 1000 1,000 for sulfur, 1400 and 1,400 for nitrogen.
碳的是,硫的是,而氮的是。
Here is the atomic nitrogen, here is the atomic nitrogen and these are the orbitals of molecular nitrogen.
这是氮原子,这是氮原子,然后这是氮气的分子轨道。
So we can put actually all 4 of our extra electrons in between the carbon and the nitrogen.
因此我们可以把这剩下的,四个电子都放在碳和氮之间。
So, for instance, this would suggest to us by the way it's written that the hydrogen is attached to the nitrogen and not the oxygen.
因此,比如,这样的写法会提醒我们,这个氢原子是与氮原子成键的,而不是氧。
