Electronegativity is one of the most well-known models for explaining why chemical reactions occur. Now scientists have redefined the concept with a new, more comprehensive scale. Electronegativity is ...

A new model rectifies the long-standing deficiencies of the electronegativity concept. Researchers from Skoltech have developed a simple, universal formula that accurately predicts the chemical ...

The number is a measure of electronegativity – how badly atoms want to hang onto (or attract) their electrons. Fluorine, which is the most electronegative element, not only wants to hang to its own ...
