So we'll talk specifically about drawing Lewis structures and then about formal charge and resonance, which are within Lewis structures.
因此我们会专门讲一讲,如何来画路易斯结构,然后再讨论形式电荷与共振论,它们也属于路易斯结构的范畴。
OK PROFESSOR: Valence electrons. OK, sometimes you're going to be asked to draw a molecular orbital diagram where you're asked to include all electrons, and sometimes it will specifically say only include valence electrons.
教授:价电子,有时候你画一幅分子轨道图,有时候要求你画出所有的电子,有时候特别要求,只包括价电子。
But since in drawing Lewis structures actually, in some cases you do, you can draw a dotted line that means a 1 and 1/2 bond, but most in most cases, we just draw out both resonance structures, and the way that we say it's a resonance structure is that we put it in the brackets and we put an arrow between it.
但是由于在画路易斯结构时,其实,在某些情况下是可以的,你可以画一条虚线来表示一又二分之一键,但是在多数情况下,我们就把两个结构都画出来,而我们说这是一个共振结构的表示的方法是,把它们放在括号里,并在中间放一个双箭头。

So, if we look at this graph where what we're charting is the internuclear distance, so the distance between these two hydrogen atoms, as a function of energy, -- what we are going to see is a curve that looks like this -- this is the general curve that you'll see for any covalent bond, and we'll explain where that comes from in a minute.
因此,如果我们来看一看这幅曲线图,这里我们画的横坐标是核间距,也就是这两个氢原子之间的距离,纵坐标是能量,我们看到的这是能量关于核间距的曲线-,这是一条普遍的曲线,在研究任何共价键时你都会遇到,我们马上就会解释一下它是怎么来的。
