    Cesium is very rare.  However, if one could find a lump of solid cesium and throw it in water, it would certainly make an entertaining explosion.  We can predict this due to cesium’s position on the table.  It is in the alkali metal family, and therefore reacts similarly to other alkali metals.  Alkali […]

Lithium is used in batteries in cell phones. The flow of electrons through a lithium battery can be explained by the following reactions: Li (in graphite) –> Li+ (aq) + e– (half reaction at negative electrode) Li+ (aq) + e– –> Li (in CoO2 ) (half reaction at positive electrode) Overall reaction: Li(in graphite) –> […]
