[etc etc]
   I think I've got a better idea. By all means let each button send a 
"DisplayElement" message, which is handled by the card script -- but use custom 
properties to store the actual data. Thus, button "Hydrogen" could have a property 
called Name, whose value is "hydrogen"; a property called AtomicNumber, whose 
value is 1; etc etc etc. Thus, the script of each button ends up looking like 
this:

on mouseUp
  DisplayElement (the short name of me)
end mouseUp

   And in the card script, we have:
on DisplayElement DisBtn
  put the Name of button DisBtn into field "ElementNameField"
  put the AtomicNumber of button DisBtn into field "AtomicNumberField"
  put the AtomicMass of button DisBtn into field "AtomicMassField"
  put the AtomicRadius of button DisBtn into field "AtomicRadiusField"
  put the IonicRadius of button DisBtn into field "IonicRadiusField"
  put the OxidationStates of button DisBtn into field "OxidationStatesField"
  put the State of button DisBtn into field "StateField"
  put the Density of button DisBtn into field "DensityField"
  # and so on, and so forth, for all the bits of data
end DisplayElements

   You could take thiperty of each button, and putting a list of all the 
relevant fields into a custom property of the card. Once you do that, the handler 
in the card script can be condensed down to this:

on DisplayElement DisBtn
  repeat with K1 = 1 to the number of items in the FieldList of this card
    put item K1 of the ElementData of button DisBtn into field (item K1 of 
the FieldList of this card)
  end repeat
end DisplayElement

   Hope this helps...
