Now, ask yourself this, especially if you're talking about Greeks, are they going to keep shelling out money for an oracle that gives them answers that turn out to be wrong? No.
现在想想这个,尤其说到古希腊人,为了得到神谕,他们会不停地破费,而这些神谕最后还是错的吗,当然不会
So you're talking right now about what will happen later on,
你是在当下讨论即将发生的事情。
If we go to the oxygen atom, now we're talking about starting with 6 in terms of valence electrons again, but instead of 2, you can see we have 6 lone pair electrons around the oxygen minus 1/2 of 2, so we have minus 1 is our formal charge.
如果我们分析氧原子的话,现在我们讨论的还是,从六个价电子开始,但孤对电子不再是两个了,你会看到氧周围,有六个孤对电子,再减去二的一半,因此我们有一个负的形式电荷。
