The core electrons tend not to be involved in much chemistry in bonding or in reactions.
核电子倾向于不参与结合，或者反应。
We very rarely would see these core electrons actually being involved in any type of a reaction.
我们极少见到芯电子，会参与任何类型的反应。
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。
The process would also create large numbers of electrons and positrons at the core of the Milky Way.
这个过程也会在银河中心产生大量的电子和反电子。
The core of the star gets compressed so much that the protons and electrons within it combine to become neutrons.
这时星体的核心会被压缩得非常紧密以至于内部的质子和电子会结合在一起转变为中子。
