ROUND 3: Science - Playing Mendeleyev

When Dimitri Mendeleyev invented the periodic table, many elements
were yet to be discovered; he predicted their properties from those
of nearby elements.  In this round you have a simpler task: all
you have to do is tell us the names of some of the elements we've
removed from the table in the handout.  You may find it helpful to know that wherever
the bottom of a square in the table shows a gray bar in place of an
atomic weight, this indicates that the element is radioactive.

 1. Tell us the name of element 86.

	Radon                  

 2. Element 7.

	Nitrogen              

 3. Element 26.

	Iron                 

 4. Element 79.

	Gold                

 5. Element 19.

	Potassium         

 6. Element 53.

	Iodine             

 7. Element 13.

	Alumin(i)um      

 8. Element 94.

	Plutonium       

 9. Element 43.  Hint: This element is not found in nature.

	Technetium     

10. Element 57.  Hint: consider the other name for the rare earth series.

	Lanthanum (we'll generously take "lanthanium" or "lathanum" as
	close enough, but do not accept "lanthanide", which _i_s the other
	name for the rare earths)


And the other missing entries are:

   Element 5 - boron               Element 56 - barium
           8 - oxygen                      72 - hafnium
           9 - fluorine                    88 - radium
          16 - sulfur  (sulphur)           92 - uranium
          50 - tin                         93 - neptunium
