WebAnd this is explained if we look at fluorine's valence shell (the second shell) electron configuration: 2s^ (2)2p^ (5). The second electron shell holds a maximum of 8 electrons and 8 electron would be considered a filled valence shell and would therefore be stable and unreactive. But fluorine has 7 valence electrons, 1 away from being filled. WebApr 16, 2007 · On the other hand, O, S, and those elements below each has 6 electrons in the outer shell or 2 short of filling the outer shell with 8 electrons. The number of electrons in the outer shell determines the element's chemical properties. There is a maximum number of electrons allowed in each shell.
