Kalzium is an open-source educational chemistry application that provides an interactive periodic table of the chemical elements for the KDE desktop environment.
Background
The program includes information on over 100 chemical elements, such as atomic mass, electric charge, images, discovery details, chemical data, and energetic properties including electronegativity and atomic radius. It also features visualisations of atomic models.
The periodic table can be configured to display numbering schemes, states of matter, and colour coding in various ways. In addition, a data timeline allows users to display only those elements discovered up to a selected year.
Kalzium is distributed as part of the KDE Education Project and has been included in educational Linux distributions such as Edubuntu.[2] The software is available in multiple languages.[3][4]
Etymology
The name Kalzium derives from the German word for calcium, reflecting the nationality of its original developer, Carsten Niehaus.
