So, if we compare the sulfur to the oxygen, the oxygen it turns out is more electronegative and that is what holds the negative charge in this molecule.
因此,如果我们来比一下硫和氧,氧应该有更高的电负性,而在这个分子中它确实有负的电荷。
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。
