RECENT advances in our knowledge of the structure of the atom have added very little to the elucidation of the nature of the metallic state, and in this connexion a very suggestive paper by Prof. C. A ...

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 ...
