Why is fluorine so anomalous? - Chemistry Stack Exchange
Feb 13, 2026 · Fluorine atoms might quantum-tunnel just as hydrogen ones, minding that their radii closely resemble each other, and because of it nonrigidity of $\ce {PF5}$ via Berry pseudorotation …
Why does chlorine have a higher electron affinity than fluorine?
Nov 12, 2013 · Fluorine, though higher than chlorine in the periodic table, has a very small atomic size. This makes the fluoride anion so formed unstable (highly reactive) due to a very high charge/mass …
intermolecular forces - Why does fluorine form only one hydrogen …
Dec 18, 2023 · Fluorine in hydrogen fluoride can form only a limited amount of hydrogen bonds because there is only one (protic) hydrogen atom per fluorine. Ammonium fluoride has enough protic …
Spontaneity and nature of attack of fluorine gas on aluminum
Apr 13, 2021 · 7 What is the nature of the reaction of attack of fluorine gas on aluminium metal? Is it spontaneous in nature? I have studied reactions of halogens on aluminium, but it had no information …
Oxidation state of fluorine in HOF - Chemistry Stack Exchange
Aug 30, 2016 · What should be the oxidation state of $\\ce{F}$ in $\\ce{HOF}$. As fluorine is the most electronegative element in the periodic table, it should be $-1$. But when I googled it, I found that …
inorganic chemistry - Why is fluorine more reactive than chlorine ...
Feb 16, 2017 · This is shielding. Lastly, fluorine is much smaller molecule than chlorine, and the shorter distance, or radius, between the nucleus and the electron again makes it more likely to attract the …
inorganic chemistry - Why is fluorine the most electronegative atom ...
Feb 27, 2014 · It seems related to the atomic size but hydrogen has a smaller atomic size than fluorine. Why is fluorine the most electronegative atom?
halides - Can fluorine ever have a positive oxidation state ...
May 5, 2021 · I know fluorine is the most electronegative element but can we humans ever synthesize fluorine in a positive oxidation state like +1?
Does fluorine have 5 or 7 active valence electrons?
Nov 2, 2021 · Fluorine is listed as 5 "active" valence electrons, implying perhaps that the 2s electrons do not participate in bonding. Why is fluorine treated differently than oxygen (or does oxygen make …
Why does fluorine atom have a higher ionization energy than oxygen …
Apr 26, 2022 · Both oxygen and fluorine (and nitrogen, carbon, boron and neon) have a $\mathrm {2p}$ orbital as their highest occupied, so we expect to ionise from that. If you draw a trend of the …
