WebThe 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. Web4 aug. 2024 · Therefore, a single carbon atom contributes: 4 x 1 = 4 Valence Electrons. Fluorine is in group 17 of the periodic table with the electronic configuration [He] 2s22p5. Therefore, the four Fluorine atoms present contribute: 7 x 4 = 28 Valence Electrons. Therefore, the total number of valence electrons in CF4 is given by:
