在 ClO3- 离子中,氯(Cl)原子的形式电荷(formal charge)为多试温,听到滋滋声表示温度足够,即可倒入适量作法1的蛋汁,接著摇动锅面让蛋汁均匀分布,待蛋汁呈现约半熟不会再滑动状态、且锅边...

我们还可以把形式电荷算出来,显然这两个原子的形式电荷,应该是完全相同的,我们要处理的只有氧这一种原子。
We could also figure out the formal charges, and obviously the formal charges between these two atoms, they're going to be identical, we're only dealing with oxygen atoms here.
如果我们想算出碳原子的形式电荷,我们需要将价电子的个数,也就是四,减去孤对电子的个数,它是多少?是二。
So, if we want to figure out the formal charge on the carbon, we need to take the number of valence electrons, so that's 4. We need to subtract the lone pair, what number is that? It's 2.
那么请大家来告诉我亚硫酰氯中,的硫原子应该有多少形式电荷?
So why don't you tell me what the formal charge should be on the sulfur atom of thionyl chloride?
And in this case, the tie-breaker goes to the molecule in which the negative charge is on the most electronegative atom.
而在这种情况下,我们需要进行“附加赛“,也就是看看分子中带有负的,形式电荷的原子是不是电负性最高的。
