The mostreactivemetal on the periodic table isfrancium. Francium, however, is a laboratory-produced element and only minute quantities have been made, so for all practical purposes, the most reactive metal iscesium. Cesium reacts explosively with water, though it is predictedfranciumwould react eve...

KHANNA is right, he and his colleagues have found a portal to another periodic table of sorts, this one populated by metal cluster "superatoms" that mimic the atoms of the original table. Their latest superatom, an Al 7 -cluster, behaves like a single multivalent germanium atom ( Proc. ...

We are just beginning to understand the metabolism of heavy metals and to use their metabolic functions in biotechnology, although heavy metals comprise the major part of the elements in the periodic table. Because they can form complex compounds, some heavy metal ions are essential trace elements...
