The body has a very complex structure, but in drawing, we must remember that everything can be broken down into geometric shapes.

But while a drawing can be rich in information, it's information that's usually inaccessible to computers.

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。
It's always a good first approximation, because you need to start somewhere in terms of drawing Lewis structures, but then if you go and figure out the formal charge and you just have lots of charge separation or very high charges, like a plus 2 and a minus 2 and a minus 1 all different places in the atom, what it should tell you is maybe there's a better structure.
它总是一个好的第一近似,因为在画路易斯结构的时候,你总需要一个起点,但是如果你在算出形式电荷之后,发现有很多电荷分开了,或者说有很高的电荷,比如有一个正二,一个负二,还有一个负一1,在原子的各个地方,这应该就是在告诉你,或许还有一个更好的路易斯结构。
