HF is a liquid at room temperature under 1 atm pressure. This is due to higher b.p. of HF than other hydrogen halides. Smaller size and highest electronegativity of F result in extensive intermolecular H-bonding in HF, which increases the b.p..
It is found that regardless of the alkyl chain length or the lateral fluorine substitution, all of the prepared materials are liquid crystalline exhibiting nematic phases composed of cybotactic clusters of the SmC-type (NCybC) in addition to a monotropic SmC phase for the longest homologue....
Within the framework of fluorine-18-fluorodeoxyglucose-positron emission tomography-computed tomography (FDG-PET/CT), the maximum standardized uptake value is determined.Pre-PBT F-FDG-PET/CT scans (cutoff 10) revealed consequential differences in overall survival rates (OS).A statistically significant ...
The Liquid Metal:Most elements of the periodic table are solid at room temperature. Some of them are gases at room temperature. The gas elements are all noble gases plus nitrogen, oxygen, fluorine, chlorine and hydrogen. There are only two elements with the liquid state among all element...
In addition, the strong electronegativity of fluorine precludes any homolytic cleavage of the C–F bond and is thus in favor of the heterolytic cleavage of the C–O bond in HMBPP 31. The similar Km values for the phosphonate analogue 92 and for HMBPP 31 suggest a similar binding for the...

Fluorineis a pale, highly-reactive gas that was first identified in the late 19th century. On the periodic table, Fluorine is the 9th element listed and can be found under the symbolF. The substance that’s added to drinking water is fluoride, which is an ion of fluorine. ...
