Negative 1 plus 0 should add up to negative 1, if in fact, we're correct for the c n anion.
负一加上零应该等于负一,如果是这样,我们对于氰离子的结果就是正确的。
So then in order to figure out the complete number of valence electrons in our molecule, we just add 5 plus 4 plus 1.
那么接下来为了得到,这个分子中价电子的总个数,我们只需要将五加上四,再加上一。
So, we need to actually add on this fourth quantum number, 1/2 and it's either going to be plus 1/2 or negative 1/2.
所以我们需要加上这第四个量子数,它等于1/2或者负的。
But here we're going to add 1, so again, we have 10 valence electrons.
但是这里我们要加上一个,那么跟刚才一样,我们有十个价电子。
So we need to add 1 more.
因此我们需要再加上一个。
So if we're comparing the difference between these 2 now, what you'll notice is that in nitrogen we have all half-filled 2 p orbitals, and now, once we move into oxygen, we actually have to add 1 more electron into 1 of the 2 p orbitals.
那么如果我们来比较下它们两个有什么不同,你会发现氮的,2,p,轨道,都是半满的,现在,我们继续看一下氧,我们不得不在其中一个,2,p,轨道上,再放上一个电子。
