I've thought about that for years, never taking the time to make it happen. 
The trick is not just to list the elements in a Python dictionary, with 
physical attributes, but to provide various filter and search operations -- 
list all metals, nobel elements, given a weight range return the matching set 
of elements, handle isotope mapping back to their base elements, etc. 
Designed and documented well, it would be a neat component.
