Miao identified two compounds that could form and remain stable up to very high pressures: cesium trifluoride (CsF3), where cesium has shared its one valence electron and two from an inner shell ...

Magnetic Super-atoms Discovered Date: June 16, 2009 Source: Virginia Commonwealth University Summary: Scientists have discovered a "magnetic superatom" -- a stable cluster of atoms that can mimic ...

To form cesium trifluoride (CsF 3), a cesium atom would share its single valence electron and two inner-shell electrons with three fluorine atoms. Four inner electrons would go into making cesium ...

Pure atoms—some clocks use cesium, others use elements like rubidium—have a certain number of valence electrons, or electrons in the outer shell of each atom.

The newly discovered cluster, consisting of one vanadium and eight cesium atoms, ... it tends to lose or gain valence electrons to acquire a stable configuration.

Are the fundamental constants really constant? Recent investigations have shown that one essential fundamental constant -- namely the mass ratio of protons to electrons -- can have changed only by ...
