Kalzium (German for: Calcium) is a periodic table of the elements for KDE Software Compilation 4. KDE is an international free software community. This software contains information about 103 chemical elements, including mass, charge, picture, discovery information, chemical and energy data, and a model of the atom. The table itself can be configured to display numeration, state of matter, and colour-coding in various ways. Additionally, a date index is available, allowing only elements discovered up to a defined year to be shown.

ICT Competency

  1. Kalzium is a tool for Subject Specific Resource creation.

Educational application and relevance

Kalzium is an application which allows an exploration of elements and properties, their classification and is based on the Periodic Table of Elements. It is possible to group and visualize elements based on various physical and chemical properties.
Kalzium provides a fascinating way to explore the periodic table. Using the left-hand panel, users have access to the time line, boiling point, and melting point sliders. When users move these sliders, the elements on the periodic table change colour according to their dates of discovery, boiling points, or melting points respectively. Users can then start to see patterns emerging in the periodic table right in front of their eyes.


This tool has no specific configuration requirements. Language settings can be selected from the Help menu

Overview of Features

This is an interactive tool to understand the properties of elements, formation of molecules and performing different calculations for determining various properties. Some important features include:

The Atom Model page displays the atomic shells. Every orbit stands for a atomic shell and every yellow circle represents an electron. The Isotopes page presents information about the isotopes of an element with information on mass, number of neutrons, percentage of isotope (abundance), half life period, energy and mode of decay, spin and parity and magnetic moment.
Kalzium 8.png The Spectrum page shows you elements spectrum. You can choose the range of the wavelengths, units and type of the spectrum. The intensity table can be seen at the right bottom part of the page.

Ideas for resource creation

Kalzium is an interactive tool for exploring properties of elements and for learning more about compounds and properties. This does not produce an output by itself (like a video, etc) It can be combined to create resources in the following ways:

  1. Screen shots can be integrated with text to make slide shows, quizzes, etc
  2. AV communication by combining with video clips
