But let's not try and figure out what's going on with this big, big example because we'll get really tired.
但是我们不用去想,这个超大的例子是怎么运行的,因为那太累人了,哦实际上,在我们这么做之前。
for example, in the exams I take time to like figure out what words I want to use
比如说,考试的时候我要费时间想我要用哪个词,
You just need to remember what's happening to z effective, which really tells us what's happening with all the trends, and once you know z effective, you can figure out, for example, what direction the atomic radius should be going into.
你只需要记住有效核电量的规律,实际上它会告诉我们所有的规律,只要你知道了有效核电量的规律,你就可以判断,比如,原子半径会向着哪个方向发展。
People use bin packing algorithms to figure out, for example, how to load up container ships.
人么通常用装箱算法来计算这个问题,比如说怎样装载货船。
So let's look at another example, Li2 let's take lithium 2 and see what we can figure out here. In lithium 2, we have two atoms of lithium, each have three electrons in them.
让我们看另外一个例子,我们看一看,看我们能得到什么,在Li2中,我们有两个Li原子,每个带有3个电子。
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。
