But unlike the case with boron where we had an empty p orbital, we're actually going to have an electron in the p orbital of carbon as well.

但和硼里面有个空的p轨道不同，我们实际上有一个电子,在碳里p轨道里也有电子。

if we move up one of our electrons into an empty p orbital, what were going to see is now we have three unpaired electrons that are ready for bonding.

教授：嗯，如果我们把其中,一个电子填入p轨道。

Keep in mind we do have this p orbital here and it's coming right out at us. And this p orbital is here, but it's empty, it doesn't have any electrons in it, that's why we don't have to worry about it in terms of getting our electrons as far away from each other as possible.

他们程120度角互相远离,这样它们离得最远，记住我们这里确实有个p轨道，它朝向我们，这里有个p轨道，但它是空的,里面没有电子,这就是为什么我们在考虑。
