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.

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。

So, for example, if we needed to figure out the electron configuration for titanium, 4s2 it would just be argon then 4 s 2, 3d2 and then we would fill in the 3 d 2.

所以举个例子,如果我们需要解出钛的电子构型，它会是Ar然后，然后我们填充。
