![]() ![]() Not quite as much fluorine as Teflon, but still quite a bit of it. Here is the company's version (there is some variation between sets, so the pictures sometimes show different variations of the samples):įreon-22 is Chlorodifluoromethane, or CHClF2. Or you can see both side-by-side with bigger pictures in numerical order. You can see photographs of all the samples displayed in a periodic table format: my pictures or their pictures. I have two photographs of each sample from the set: One taken by me and one from the company. To learn more about the set you can visit my page about element collecting for a general description or the company's website which includes many photographs and pricing details. So there may be some silicon fluoride lining the inside of the glass, but there is virtually no chance that there is any element fluorine still inside. Glass will actually burn in a stream of pure fluorine (video coming soon). No doubt the glass ampule did at one time contain elemental fluorine: You can tell because it ate the glass on its way out. ![]() Max Whitby, the director of the company, very kindly donated a complete set to the periodic table table.Īlmost all the samples in the set are very, very nice, but this one I have to tease a little bit. The Red Green and Blue company in England sells a very nice element collection in several versions. To learn more about the set you can visit my page about element collecting for a general description and information about how to buy one, or you can see photographs of all the samples from the set displayed on my website in a periodic table layout or with bigger pictures in numerical order. Although it's possible to store fluorine in special containers (see the next sample) it's quite obvious that this is not such a container. Elemental fluorine cannot be contained in ordinary glass: It eats the glass. This sample is not marked as being a dummy (as the radioactive ones in the set are), but it obviously is. The samples (except gases) weigh about 0.25 grams each, and the whole set comes in a very nice wooden box with a printed periodic table in the lid. At some point their American distributor sold off the remaining stock to a man who is now selling them on eBay. Up until the early 1990's a company in Russia sold a periodic table collection with element samples. These tablets contain sodium fluoride and are meant to be taken to prevent tooth decay by people whose water supply is not fluoridated. It came packaged very elaborately so you could pull it out and use it immediately without any danger of it tangling. This is lovely Gore-Tex (Teflon) surgical suture, with single-use needle attached. Look it up if neither of these words mean anything to you. There's probably some in this fused quartz bulb (if it hasn't eaten its way out yet).Ĭlick here to buy a book, photographic periodic table poster, card deck, or 3D print based on the images you see here!Ī Teflon stopcock from a burette. Pictures, stories, and facts about the element Fluorine in the Periodic Table Hįluorine is a pale yellow gas that reacts violently with virtually everything, including glass.
