但是每个氟原子现在都有八个电子，或者说周围有一个填满的八隅体。

But that each individual fluorine atom has eight electrons, or full octet around it.

因此要填满我们的“八隅体“,排满所有的价壳层，我们总共需要十八个电子。

So in terms of total numbers that we would need to complete our octets and fill our valence shells, we would need 18 electrons.

而如果我们继续到第三步,判断一下填满所有“八隅体“需要多少个价电子，结果应该就是二乘以八，也就是十六个。

And if we go on to step three where we figure out how many we would need for full octets, it's just going to be 2 times 8, so we have 16.

youdao

So in order to fill them, he would have to have eight electrons or an octet around the cubes.

因此为了填满它们，他必须放上八个电子或者说一个“八隅体“,在立方体周围。

Our step three is to figure out how many bonding electrons that we need, or excuse me, how many total electrons that we need to fill up our octets, so that's just going to be 4 times 8, which is 32.

我们的第三步是判断,我们需要多少个成键电子，不好意思，是我们总共需要多少个电子,才能填满所有“八隅体“,那么这就应该是四乘上八，也就是三十二。

We'd have to figure out a way to achieve octet stability by electron transfer.

我们需要找到一个可以通过电子转移,而实现八隅体的方式。
