BUFFALO, N.Y. — You probably learned in high school chemistry class that core electrons don’t participate in chemical bonding. They’re thought to be too deep inside an atom and close to the nucleus to ...

To investigate such double core-hole states in highly ionized Krypton, a colorless, odorless gas found in trace amounts in ...

Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto a higher energy level, a ...

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 ...

After few femtoseconds, the double excited state decays by electron emission, generating a higher charge state. Compared to ...

Researchers resolve the age-old mystery of why silicon cannot replace carbon in organic compounds. A new benchmark quantum chemical calculation of C2, Si2, and their hydrides for the first time ...

The world's first kiloelectronvolt X-ray laser produces such a high flux of photons that atoms can be 'cored'. In other words, the light source can knock out both the electrons of an atom's innermost ...

A messy paradox that has plagued geoscientists who study Earth's core and the magnetic field it produces may now be solved. The puzzle is only a few years old. It was raised in a 2012 paper in which ...

You probably learned in high school chemistry class that core electrons don’t participate in chemical bonding. They’re thought to be too deep inside an atom and close to the nucleus to meaningfully ...

You probably learned in high school chemistry class that core electrons don't participate in chemical bonding. Subscribe to our newsletter for the latest sci-tech news updates. They're thought to be ...

A University at Buffalo study provides new insights about core electrons, including their role in the B1-B2 transition that sees a compound's atomic crystal structure rearrange from an octahedral ...
