UK?? It's Elemental!

The University of Kentucky (UK) & The United Kingdom (UK).  How about Uranium-Potassium (UK)?  Well, both chemical elements are metals - the large majority of elements are metals.  What else to they have in common? Very little, best I can tell.  But their chemical symbols spell out "UK".  No isotope of uranium is stable.  That is, they are all radioactive.  But potassium does have non-radioactive (stable) isotopes.  Uranium is the heaviest naturally occurring element and contains the largest number of protons in the nucleus of any element found naturally on earth (92 protons).  Potassium is a much lighter metal but is much more chemically reactive.  In fact, pure potassium reacts explosively with water and very rapidly with the oxygen in the air.  Thus, in the pure elemental form, it must be stored in an inert atmosphere or inert solvent.  Potassium (K) is an alkali metal in Group 1 of the Periodic Table.  Uranium (U) is an actinide and is technically in Group 3 along with all the other Lanthanides and Actinides.  These elements are typically displayed along the bottom of the Periodic Table.  The former elements follow Lanthanum (La) in the Table and the latter elements (including Uranium) follow Actinium (Ac) in the Table.  How about some "UK" action?  Follow these links.  Be sure to wear Safety Glasses!  ;-)
