External links modified (February 2018)

Hello fellow Wikipedians,

I have just modified one external link on Fluorine. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

• Added archive https://web.archive.org/web/20120208080640/http://www.halocarbon.com/halocarbon_media/swinson_109.pdf to http://www.halocarbon.com/halocarbon_media/swinson_109.pdf

Pictures Appear Broken

It may just be me, but it looks like the photographs on part of the page are too large. It breaks the page and I have no idea how to fix it.

might be related to recent "upright" edit. Which images are affected? I am mobile now so will take a look later on. -DePiep (talk) 20:42, 17 June 2018 (UTC)

The image galleries titled Major fluorine-containing minerals and Structural progression of metal fluorides. I, too, am having problems with the pictures in them suddenly becoming way too large. We might be better off sticking to the hard-coded px sizes for a while until upright is fixed; if you agree, please feel free to execute this idea.--R8R (talk) 21:53, 17 June 2018 (UTC)

please revert my recent "upright" edit then. i cannot do that by mobile. -DePiep (talk) 22:13, 17 June 2018 (UTC)

Unfortunately, I do not know what exactly governs this upright parameter. If you tell me, then I will. Also, you can switch to the desktop mode on your smartphone; the link is at the bottom of any mobile Wikipedia page, labeled "Desktop."--R8R (talk) 22:24, 17 June 2018 (UTC)

The |upright= parameter can only be used in conjunction with either |thumb or |frameless (see WP:EIS). It applies a scaling factor to the default width, which is 220px (unless changed in preferences by a logged-in user); so using |thumb|upright=0.9 or |frameless|upright=0.9 together, the width becomes (220 * 0.9) = 198px, which the MediaWiki software rounds to 200px wide. For the case where [[File:Fluorite-270246.jpg|upright=0.9|alt=Pink globular mass with crystal facets]] was attempted, try [[File:Fluorite-270246.jpg|frameless|upright=0.9|alt=Pink globular mass with crystal facets]] instead. Similarly with the others. --Redrose64 🌹 (talk) 18:54, 18 June 2018 (UTC)

"Fluroine" listed at Redirects for discussion

Fluorine for Dental Care?

Section 7.1 (Medical applications - Dental care) discusses "Fluoride" and not "Fluorine". I'm no chemist, but I think this information would be better suited on the Fluoride page? CanucksGirl (talk) 22:40, 18 November 2020 (UTC)

Natural source of fluorine-18?

The radioactive isotope fluorine-18 is listed as having a natural abundance of "trace", implying that it does indeed have some natural occurrence. But what would be the natural source of it? The fluorine-18 article doesn't talk about any natural sources. It has a short half-life, suggesting it would be generated by radioactive decay, but I couldn't find any natural decay chains it's apart of. Saucy^{[talk – contribs]} 10:13, 19 November 2022 (UTC)

Neither can I find evidence in reliable sources of natural occurrence outside of the CNO cycle. –LaundryPizza03 (dc̄) 23:33, 19 November 2022 (UTC)

Cosmogenic nuclide lists ¹⁸F, as both a result of cosmic ray spallation on atmospheric argon, and a product of the ¹⁸O(p,n)¹⁸F reaction. A source is given: it's in Table 1.9 here. Double sharp (talk) 00:35, 20 November 2022 (UTC)

@Saucy and LaundryPizza03: I added the cosmogenic natural occurrence of ¹⁸F (with the source) to the articles fluorine and fluorine-18. So this should be resolved now.

P.S. John Emsley's Nature's Building Blocks (2011 edition, on p. 183) notes that ²³F is a natural product of cluster decay of natural ²³¹Pa. But given the extremely low branching ratio, this is probably not important enough to include (I can't find any other source). Double sharp (talk) 19:35, 20 November 2022 (UTC)

Thanks! I wouldn‘t have been able to understand that source well enough to add it myself. Saucy^{[talk – contribs]} 21:08, 20 November 2022 (UTC)
