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. WebAug 14, 2024 · The first two electrons in lithium fill the 1 s orbital and have the same sets of four quantum numbers as the two electrons in helium. The remaining electron must occupy the orbital of next lowest energy, the 2 s orbital (Figure 8.3. 3 or 8.3. 4 ). Thus, the electron configuration and orbital diagram of lithium are:
