Research suggests some metals’ semicore electrons may be more active on Earth’s surface than previously thought.

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 ...

IN the development of the resonating-valence-bond theory of metals, it has become evident that the characteristic structural feature of metals is the possession by each atom or each of many atoms in ...

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