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.
Swap out openSUSE_Leap_15.2 for openSUSE_Leap_15.1, openSUSE_Leap_15.0, or openSUSE_Tumbleweed if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
