Kalzium is a program that shows you the Periodic Table of Elements. You can use Kalzium to search for information about the elements or to learn facts about the periodic table. It provides an overview of the important data (like melting points, electron affinity, electron negativity, electron configuration, radii, mass, ionisation energy), an isotope table, and different colored views of the periodic table (separation of the different blocks, year simulator, temperature simulator). It contains tools to visualize the spectral lines of each element, a molecular weight calculator, a 3D molecule editor, and an equation solver for stoichiometric problems.
The packages for RHEL 8 and RHEL 7 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 8 and RHEL 7, which is why they’re listed separately below.
The EPEL repository can be added to RHEL 8 with the following command:
