So if we want to put that in chemical terms, we want to make sure we put these in brackets here, and remember, this is the resonance arrow, it's not a reaction arrow, it's a resonance arrow, so make sure you mark it up correctly like that.
那么如果我们把它类比到化学中来,我们要确保它们都放在括号里,而且要记住,这是一个表示共振态的箭头,而不是表示化学反应的,它是一个表示共振态的箭头,因此请务必像这样正确地标记它。
So one last concept that I want introduces is this idea of resonance.
我要介绍的最后一部分内容,是共振态这个概念。
And resonance is the idea that sometimes one single Lewis structure does not adequately describe the electron configuration around a given molecule, so instead you need to draw two different Lewis structures to describe that more appropriately.
而所谓共振态,就是有时候一个路易斯结构不足以,完整描述一个给定分子的电子排布,因此这时你需要同时画出两个,不同的路易斯结构来描述它,这样会更恰当。
