Fluorine is in the [[halogens]] group. The [[atomic mass]] is 18.9984 g/mol. The natural phase of Fluorine is gas. Fluorine is the most electronegative element on the periodic table, so it can be easily combined with any other element. In addition, because it is highly reactive, it also can react with [[hydrogen]]. The reaction can be explosive. The reaction is very dangerous especially with [[water]]. | Fluorine is in the [[halogens]] group. The [[atomic mass]] is 18.9984 g/mol. The natural phase of Fluorine is gas.
