Inert gases like neon and argon have eight electrons in their outer shell.
像氖和氩这样的惰性气体,在它们的外电子层有8个电子。
Whereas for fluorine, fluorine is smaller than f minus is the one that's the outer shell shown here.
而对于氟来说,氟原子更小,与外部壳层在这的负一价氟离子相比。
Only electrons in the outer shell can form chemical bonds, so the elements in each column are chemically similar.
只有外层内的电子才会形成化学键,因此每一列中各元素化学性质均相似。
So the 3 s 1, or any of the other electrons that are in the outer-most shell, those are what we call our valence electrons, and those are where all the excitement happens.
它们是经常发生激发情况的,那也是我们所看到,我们称之为价电子,它们是经常发生激发情况的。
Whereas for fluorine, fluorine is smaller than f minus is the one that's the outer shell shown here.
而对于氟来说,氟原子更小,与外部壳层在这的负一价氟离子相比。
And, these outer shell electrons are termed valence electrons.
这些外层电子被,称作价电子。
