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 ...

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.

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 ...

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 ...

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.
