In 1923, the year C&EN was born, Gilbert N. Lewis of the University of California, Berkeley, published a book titled “Valence and the Structure of Atoms and Molecules.” In the text, Lewis laid out the ...

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the ...

You probably learned in high school chemistry class that core electrons don't participate in chemical bonding.

Scientists have managed to successfully make a transuranium complex where the central metal, here neptunium, forms a multiple bond to just one other element. Enabling study of such a bonding ...

It’s a helpful rule of thumb: Main group elements prefer forming bonds that give them eight valence electrons; transition metals go for 18 electrons. Now scientists have shown that main group elements ...

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was observed for the first time. As the interactions between atoms are governed by the valence electrons ...
