Perhaps future astronomers will note whether its dark matter shroud once again saves the cloud.

也许，未来的科学家就可以确定是是壳层保护了暗物质云免撞击带来的伤害了。

And two electrons can fit in that first energy state, or that first sub-orbital, or that first shell.

两个电子可以适合第一个量状态，或者第一个子轨道，或者第一个壳层。

Chemical reactions happen when an atom's outermost electrons do stuff, and the protons and neutrons and even the inner electron shells are usually completely unaffected.

当原子的最外层电子做事时就会发生化学反应，而质子和中子甚至内层电子壳层通常完影响。

The reason why it's included here is because helium is also very stable because for that first shell, you only need two electrons to feel full, to feel stable.

之所以把它包括在这里，是因为氦气也非常稳定，因为对于第一个壳层，你只需要两个电子就可以感到饱满、稳定。

The last thing it wants to do is give away electron, it wants an electron really, really, really, really badly so it can get to a configuration of argon, so it can complete its third shell.

它最想做的就是放弃电子，它非常非常非常非常想要一个电子， 这样它就可以达到氩的构型， 这样它就可以完成它的第三个壳层。

It'd be hard for it to complete that shell, and so to get to a stable state it's much easier for it to give away that one electron that it has, so it can get to a stable configuration like neon.

它很难完成那个壳层，所以要达到稳定状态， 它更容易放弃它拥有的一个电子， 这样它就可以像氖一样达到稳定的配置。
