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 ...

Players read questions about energy levels and score points by picking the correct element as the answer. Electrons are in regions around the nucleus that are different distances away from the nucleus ...

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 ...
