In fact the experiment could have revealed a residual charge as small as? E per atom and none was observed.
事实上，这个实验是能够测出小至每个原子？e的剩余电荷的，然而并未观察到任何变化。
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。
