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。
So we can bring in four hydrogen atoms, which will each contribute another unpaired electron.
我们可以引入4个氢原子,每个贡献一个未配对的电子。
And I cannot have an unpaired electron in the same orbital.
我不可能在同一个轨道,得到不成对电子。
s -- we don't have to hybridize it, it already has only one unpaired electron in a 1 s orbital.
s-我们不用杂化它,它已经有而且仅有一个未配对电子在s轨道里。
And what I want to point out that we just figured out for molecular orbital theory, is that o 2 is a biradical, because remember, the definition of a radical is when we have an unpaired electron.
我要指出的是,我们刚利用分子轨道理论,指导了O2是二价自由基,因为记住,自由基的定义是,有个未配对的电子。
