Whe you click on an element in the periodic table you will get an extensive information window divided into several tabs. Here are some examples for the element Rhodium:
The Atom Model tab displays the atomic shells. Every orbit stands for a atomic shell and every yellow circle represents an electron.
The Isotopes tab presents information about the isotopes of an element: mass, number of neutrons, percentage of atoms occurring, half-life period and more.
The Data Overview tab tells you about different facts related to the element.
Tools
Kalzium offers some more tools to explore chemical data:
Kalzium can show you which elements are solid/liquid/vaporous at a given temperature. The colorscheme is explained in the Legend at the bottom of the window.
The Timeline feature allows you to explore the elements of the set time period. This is great for getting a feel for how the PSE evolved over time. See what elements are allready discovered 1800.
The Isotope Table shows you the isotopes of the elements. Different colors represent different decay types. Move around and zoom in and out.
Kalzium offers a 3D Molecular Editor. You can compose molecules yourself or open an included example. You can rotate the view around every atom in the molecule.
