Because that will take care of all of the electrons that are capable of reacting, none of the inner shell electrons.
因为那样我们可以考虑到,除内层电子以外,所有可以发生反应的电子。
You can see that there is no value in studying inner shell electrons to ask questions about bonding.
你应该了解考虑成键时,去考虑内层电子,是毫无意义的。
If we look at this configuration, what we say is all of the electrons in these inner shells are what we call core electrons.
如果我们看到这个构型,我们所说的是,所有的内层,都是核电子。
So, the chances of getting any activity from these inner shell of electrons are vanishingly small.
所以,内层电子间,进行反应的可能性,是很小很小的。
If you look at oxygen, oxygen is 1s2, which is an inner shell electron.
你看,氧是1s2原子,1s轨道上是内层电子。
