Electronegativity and molecular polarity are central to understanding chemical bonding. By combining periodic trends with molecular geometry, you can predict whether a molecule is polar or nonpolar.

Electronegativity: In the world of chemistry, electronegativity is often considered to be an important topic. As you might be already aware, periodic trends are observed in various aspects such as ...

A Skoltech professor and his Chinese colleagues have revised a key chemical concept, electronegativity, and determined this characteristic for all elements under varying pressures. The revamped notion ...

Back in 2004, the physics community was just beginning to recognize the existence of truly two-dimensional (2D) material, graphene. Fast forward to 2019, scientists explore a breadth of different 2D ...

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 ...

Fluorine, which is the most electronegative element, not only wants to hang to its own electrons but in an extreme case of atomic avarice, also wants to steal others from different elements and is not ...

Fluorine chemists have been on a roll lately, generating a torrent of research papers reporting new tricks for incorporating fluorine into organic molecules. The field’s abundance of riches has come ...

Scientists have shown that an oxyfluoride is capable of visible light-driven photocatalysis. The finding opens new doors for designing materials for artificial photosynthesis and solar energy research ...

Talk about tough competition. According to a document prepared by the Swedish-French Association for Research, on Sept. 21, 1906, as the Nobel committee debated whom to recommend to the Royal Swedish ...
