WebJul 30, 2011 · A fluorine atom has 7 valence (outer-shell) electrons. To fulfill the octet rule, it needs one more valence electron for a total of 8. This one extra electron in the fluoride ion causes a -1 charge. WebAug 15, 2024 · Chemistry of Chlorine (Z=17) Fluorine (F) is the first element in the Halogen group (group 17) in the periodic table. Its atomic number is 9 and its atomic weight is 19, and it's a gas at room temperature. It is the most electronegative element, given that it is the top element in the Halogen Group, and therefore is very reactive.
