Chemists have recently explored protactinium's multiple resemblances to more completely understand the relationship between the transition metals and the complex chemistry of the early actinide ...

The recent emergence of signaling roles for transition metals presages a broader contribution of these elements beyond their traditional functions as metabolic cofactors. New chemical approaches to ...

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 ...

As demand for clean energy technologies surges, the United Nations has called for reform of how the extraction of critical minerals is financed. A new report by the International Resource Panel (IRP), ...
