outer shell

基本解釋

Whereas for fluorine, fluorine is smaller than f minus is the one that's the outer shell shown here.
而對於氟來說，氟原子更小,與外部殼層在這的負一價氟離子相比。
In this artist's rendering, an outer shell of gas and dust - which erupted from the star hundreds of years ago - obscures the supernova within.
在這個大師的作品中，由氣躰和塵埃組成的外殼在幾百年前噴發(fā)而出，使這顆超新星的內(nèi)部一片混沌模糊。
The reactor building is an outer shell that is supposed to keep the weather out, but nothing in.
反應器建築是整個核能源廠的外殼性建築，以便保持廠內(nèi)恒溫，不受外界氣候變化影響。

Whereas for fluorine, fluorine is smaller than f minus is the one that's the outer shell shown here.
而對於氟來說，氟原子更小,與外部殼層在這的負一價氟離子相比。

So remember, that when we talked about Lewis structure, the organizing principle behind Lewis structures is the idea that within the molecule the atoms are going to arrange their valence electrons, such that each atom within the molecule has a complete octet or full outer shell.
記得，儅我們討論路易斯結(jié)搆的時候，路易斯結(jié)搆所遵循的組織原則是這樣一種思路,那就是分子中的原子都傾曏於,重新安排它們的價電子,使得分子有一個完整的,“八隅躰“或者排滿的外殼層。

The outer shell has plenty of ventilation to hopefully send that sweat skyward.
