This page shows a partial diagram of the Periodic Table of the Elements.  Below the diagram are several compounds.  By clicking on an individual element in the periodic table, one can learn both the symbol and full name of the element, such as F e, or Iron.  By clicking on a compound name, one can learn what elements are found in that compound.  Note: The links on each element and compound do not go anywhere, they only change the appearance of the periodic table by highlighting a portion of it.  This page uses layers. What’s in it? What’s it in?
