During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical ...

The chapter Chemical Bonding plays an important role in IIT JEE, UPSEE, WBJEE and various other engineering entrance examinations. This article talks about Valence Shell Electron Pair Repulsion (VSEPR ...

A group of researchers from Ehime University investigated valence electron configurations using light, expanding on prior studies of superconductors and quantum spin liquids. The findings were ...

If phosphorous has five electrons in its outermost shell, meaning it needs only three more to fill the shell, how can it form FOUR valence bonds when used as a dopant in a silicon crystal? This is one ...

A study suggests atoms can bond not only with electrons in their outer shells, but also via those in their supposedly sacrosanct inner shells Most of us learned in high school chemistry class that ...
