Spontaneity and nature of attack of fluorine gas on aluminum
2021年4月13日 · Fluorine is one of the most dangerous substances out there, and one of the presumed products, $\ce{OF2}$, is also terrifying. If you can calculate the free energy change …
inorganic chemistry - Why is fluorine the most electronegative …
2014年2月27日 · Fluorine has a high electron affinity (easy to gain an electron) and a high ionization energy (hard to lose an electron). There are other scales, including the Allred …
inorganic chemistry - Does fluorine in FNO3 have +1 oxidation …
2016年11月9日 · The fluorine is the most electronegetive element in the periodic table that's why it is given a permanent oxidation state of -1 (0 when it is in elemental form).Since I consider …
Is F2 two fluoride ions or just one? - Chemistry Stack Exchange
2015年5月22日 · A fluorine atom can share electrons with another nonmetal to form a covalent bond. When sharing electrons in a covalent bond, the fluorine is still called an atom, because it …
Oxidation state of fluorine in HOF - Chemistry Stack Exchange
2016年8月30日 · Oxygen, the second-most electronegative element in the periodic table, has the same oxidation state as in molecular form. It is also bonded to an even more electronegative …
Why does fluorine atom have a higher ionization energy than …
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 ionisation …
inorganic chemistry - Why doesn't fluorine harm the ozone layer …
2021年1月8日 · Fluorine atoms released are quickly sequestered into carbonyl compounds and subsequently into hydrogen fluoride by reacting with water and methane molecules which is …
organic chemistry - Why are fluorides more reactive in nucleophilic ...
2013年7月25日 · I guess it's conceivable that the presence of fluorine atoms would better stabilize the Meisenheimer complex than other halogens, though I don't know for sure. Still, since all …
polarity - What determines "polarizability" of an element?
2017年6月29日 · The very uneven electron distribution of the iodine atom causes the hydrogen-iodine bond to be slightly unstable. On the contrary, since there is not so much of polarisation …
Why does a Fluoride ion only have a -1 charge and not a -2 …
In addition, consider the high charge density of the fluoride anion. Tacking on an extra electron to fluorine is OK, but not as favorable relative to the less charge dense chlorine atom. Fluorine …
