  • It was generally believed that in a metal the valence electrons are easily detached from the individual atoms .

    一般认为,在金属中 电子容易脱离个别原子。

  • For example we can talk about nitrogen and nitrogen has five valence electrons shown here .

    例如,我们可以讨论氮原子,氮原子有5个 电子

  • Then it says count all the valence electrons .

    然后它说,考虑所有的 电子

  • PROFESSOR : five & there 's five valence electrons but the atomic number is actually seven .

    教授:5,有5个 电子,但原子序数是7。

  • For our step two what we need is number of valence electrons .

    我们的第二步,需要知道 电子的个数。

  • Our next step is thinking about valence electrons .

    我们下一步要考虑的是 电子

  • So hopefully you remember what we mean by valence electrons versus core electrons .

    希望大家还记得, 电子与芯电子的定义。

  • So what if we capture all of the valence electrons .

    但是如果我们捕获了所有 电子又怎样呢。

  • So let 's just prove that to ourselves and figure out the bond order just using valence electrons .

    让我们证明一下这一点,来看看只用 电子算出键序。

    我们有七个 电子

  • All right so one thing that I first want to point outabout MO theory that is a big difference from Lewis structures is that in MO theory valence electrons are de-localized over the entire molecule .

    好了,对于MO理论低一点要指出的,是它和Lewis有着很大的区别,在MO理论里, 电子在整个分子里是去局域化的。
