    New electronegativity scale revolutionizes high-pressure chemistry

    (ORDO NEWS) — The Skoltech professor and his Chinese colleagues have revised the key concept of chemistry – electronegativity – and determined this value for all elements at various pressures. Numerous anomalies in high-pressure chemistry have been theoretically substantiated within the framework of the updated concept of electronegativity. Electronegativity and the related concept of chemical rigidity are fundamental properties of elements that largely determine how and in what reactions atoms…

    Fossil mollusk shells reveal ocean chemistry during the Permian extinction

    (ORDO NEWS) — Scientists analyzed the structure of the shells of marine mollusks that lived about 252 million years ago. It turned out that the mass extinction that occurred at that time was not accompanied by an increase in the level of ocean acidity, as previously thought. Researchers from the University of Texas at Austin (USA) and the University of Hamburg (Germany) have used fossil shells for the first time…
