Electronegativity: Read the article to find out what electronegativity is, how it is measured and what are the periodic trends in the electronegativities of elements.

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.

Researchers have discovered a new class of highly electronegative chemical species called hyperhalogens, which use superhalogens as building blocks around a metal atom. The new chemical species ...
