目前为止任何时候我们尝试要，描述分子内的成键，我们都是利用Lewis结构。

So far we've exclusively been using Lewis structures any time we've tried to describe bonding within molecules.

但它们在预测分子内，成键时不总是正确的，这是因为Lewis结构，实际上不是基于量子力学的。

But they're not accurate all the time in predicting bonding within molecules, and the reason for this is because Lewis structures are not, in fact, based on quantum mechanics.
