和离子，它是一个原子或原子的电荷组。

And ion, which is an atom or group of atoms with an electrical charge.

量子化学计算棉酚与胸腺嘧啶分子中的净电荷分布，发现沿两者结构式粗线上各原子的电荷恰好符号相反（图2）。

Quantum chemical calculations of gossypol and thymine reveal that the net electronic charge distributions along the boldfaced line of their structural formula (Fig. 2) are just opposite in sign.

如果是原子质量一定，而电子很小，那么带正电荷的部分几乎占据了全部质量。

If the atom is fixed mass, and the electron is tiny, it must be the positives have all the mass.

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。

So why don't you tell me what the formal charge should be on the sulfur atom of thionyl chloride?

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 that means that the more stable molecule is going to be this molecule here, which actually puts the negative charge on be more electronegative atom.

因此这意味着更稳定的分子,应该是这一个，它真正把负的电荷放到了,电负性更高的原子上。
