Kalzium is an application which will show you some information about the periodic system of the elements. Therefore you could use it as an information database.

Kalzium has already some nice features but there are still a lot of things to do. As Kalzium has been included in KDE 3.1 we are currently coding quite lot to bring in some new and nice features and make it as fast and usefull as possible. You can help us by testing it or make proposals for new features or a better design.


  • versatile overview of all important data from the elements like melting points, electron affinity, electron negativity, electron configuration, radii, mass, ionisation energy
  • tool to visualize the spectral lines of each elements
  • different colored views to the PSE: separation of the different blocks, Year simulator, Temperature simulator
  • Molecular weight calculator
  • an Isotopetable
  • 3D molecule editor, with a load and save functionality
  • a equation solver for stoichiometric problems
  • filetype conversion for different types of chemical programs
  • tool to produce a comprehesive list of all Risk_and_Safety_Statements
