ElementData on v9.0.1.0

Jean-Christophe Deschamps
Posted 9 years ago

Dear readers,

The doc of Mma v9.0.1.0 says we can "list all standard elements" by issuing ElementData[] and that we can as well use ElementData[n] for obtaining the name of the n-th element, or ElementData["Properties"] to get a list of all element properties. None of these work out of the box.

Is that an oversight in doc or do I need some magical wand to make them work as described?

Sorry for the broad request in multiple groups.

Hi Bruce,

Thank you for your answer, which I now can reproduce in a new notebook. I didn't understand why this didn't work before: I enjoy a professional Internet connection 24/7. I now suspect that the issue came from pasting the line from the help file and hiiting "Numpad-Enter" too quickly before realizing that the string pasted had unexpected wrappers: RefLink[ElementData,paclet : ref/ElementData][] which, once executed, defined ElementData[] (without arguments) to be its own symbol.

Yet, trying ElementData["Carbon", "AtomicWeight"] gave the expected answer in the subsequent input of the same notebook. That got me wondering.

Sorry for the noise.
