• 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。

  • When we increase the potential between the 2 electrodes that we have in the tube -- we actually split the h 2 into the individual hydrogen atoms, and not only do that, but also excite the atoms.

    当我们增大两个电极之间电压,我们有-我们可以把氢气2,分解成单个的氢原子,不仅这样,还能激发原子

  • So if we take our carbon atom here, which has two electrons in the 2 s orbital, and we promote one of these electrons into a 2 p orbital, what we see now is that yes, we do, we have four unpaired electrons.

    这是碳原子,2s轨道里有两个电子,我们把一个电子激发到2p轨道里,我们看到现在,是的,我们有4个未配对电子。
