Reaction with iron wool; Fluorine: Reacts with almost anything instantly. Fluorine is the most reactive element in Group 7, and is even more reactive than chlorine. Our Periodic Element comparison tool allows you to compare Periodic Elements properties side by side for all 118 elements | SchoolMyKids Interactive Dynamic Periodic Table, Periodic Table Element Comparison tool, Element Property trends If no precautions are taken, a mixture of fluorine and methane explodes. Chlorine gas reacts with fluorine gas according to the balanced equation: Cl 2 (g) + 3 F 2 (g) → 2 ClF 3 (g). Problem: Chlorine reacts with fluorine above 200 degrees Celsius to form chlorine trifluoride, CLF3, as shown by this equation: Cl2 (g) + 3F2 (g) ----> 2CLF3 (g) If equal numbers of moles of chlorine and fluorine are combined, the maximum number of moles of CLF3 that could be formed will be equal to: a) the number of moles of CL2 b) the number of moles of F2 c) twice the number of moles of … Chlorine has a low solubility in water which at temperatures above room temperature has a negative coefficient. At low temperatures it forms insoluble hydrates with water. The interesting reactions happen in the presence of ultra-violet light (sunlight will do). Iodine, on the other hand, does not react with methane. If the first figure represents the amount of fluorine available to react, and assuming that there is more than enough chlorine, which figure best represents the amount of chlorine trifluoride that would form upon complete reaction of all of the fluorine? The trifluoride chlorine(III) fluoride is also formed and the reaction does not go to completion. Fluorine reacts so readily with almost any substance it contacts that chemists were not successful in isolating pure fluorine until 1886, although its existence in compounds had been known for many years. Produces iron(III) fluoride. Fluorine is the most reactive. Very few scientists handle fluorine because it is so dangerous. Fluorine's outer shell is closer to the nucleus and has fewer filled shells between it and the nucleus, so the attraction for a new electron is greater and so it can gain an extra electron more easily. If will react with moisture in the air to produce oxygen, see above. We'll look at the reactions with chlorine. Reactions with halogens: Fluorine reacts with chlorine at 225°C to form the interhalogen species ClF. The reaction between methane and chlorine is easily controllable, while bromine is even less reactive than chlorine. These are photochemical reactions, and happen at room temperature. The reactions of fluorine, chlorine, bromine, and iodine with methane are quite differently vigorous. Compare Fluorine vs Chlorine of the Periodic Table on all their Facts, Electronic Configuration, Chemical, Physical, Atomic properties. Methane and chlorine. Chlorine, bromine, and iodine are progressively less reactive but still form compounds with most other elements, especially metals. The violence of the reaction drops considerably as you go from fluorine to chlorine to bromine. The reactions with bromine are similar, but rather slower.
