From the developer:
Ptable is an interactive periodic table of elements. Simply click on an element to view its details such as symbol, atomic number, atomic weight, oxidation state, melting point, boiling point, density, electronegativity, and radiation. All these data can be copied to clipboard using the "Copy" button. This is a portable application that can be run without installation.
You may want to check out more software, such as QPlot, GenealogyJ or Lapackpp, which might be similar to Ptable.
