It attempts to provide a physical basis for the valence rules,

基于八隅体和化学键共享电子的概念
based on completing octets and sharing electrons for bonds.

它试图从物理角度去阐释价态的规律
What it gives that's new is reactivity due to unshared pairs

其创新点在于用未成对电子来表现反应性
where both of the "hooks" in the bond come from the same atom,

成键时共享电子均来自这对孤对电子
And it's convenient for electron bookkeeping.

并且路易斯结构式便于标记电子
It certainly tells you what the molecular charge is.

它能清楚地显示分子中的电荷分布情况
The formal atomic charge is qualitatively realistic

由此推断的原子电荷分布也基本符合事实
as we've just seen, at least in the case of O3.

这一点至少在臭氧的例子中已被证实
And there's this question of stability and resonance.

当然还有关乎稳定性和共振论的问题
But resonance actually is not something nature knows anything about.

但共振论并不是真正的自然规律
It's just a correction we try to apply to

它只是为了便于我们使用路易斯结构式
having made drawings based on Lewis theory.

而所作的一种修正
