The information dialog is accessed by clicking with the mouse button on any element. It is available only in the Overview mode or when the sidebar is hidden. This is the place to get information about an element. With the buttons at the bottom of the dialog or with the use of the mousewheel you can change the element which is displayed without closing the dialog.
In the Overview you will find the most important information about the element. In the middle you see the symbol of the Element with it's elemental number in the top left. The bottom-left corner displays the name of the element while the bottom-right corner shows the most important oxidation-stages and, below that, the elemental weight

The Atom Model tab displays the atomic shells. Every orbit stands for a atomic shell and every yellow circle represents an electron.

The Chemical Data tab presents some atomic data. The first entry is the Orbital structure. The next is the density.
Depending on the data available in Kalzium you will see different radii of the element. The covalent radius is the radius of a non charged atom of the element in a molecule. The could for example be the O-H-distance in Water. The atomic radius is the radius of an elemental atom, e.g. not bound to anything. The van der Waals-radius is defined as the distance of two atoms of the same sort in two equal molecules, for example two carbon-atoms in propane. The last possible radius is the ionic radius including its charge.
The mass of an element is the avarage mass of all isotopes in relation to their percentage.
Some elements have information about their isotopes.
The mass of this isotope.
The number of neutrons this isotope has.
The percentage of atoms occuring that are of this isotope type. Also called abundance.
Only unstable isotopes have a half-life period. It is defined as the time in which half the isotopes decay.
Some isotopes are known to emit particle radiation under the process of radioactive decay. Each decay transformation has a typical energy release, which is listed along with the mode of decay.
The spin of the nucleus and its parity.
The magnetic dipolemoment of the nucleus. Measured in units of the nuclear magneton.

The Miscellaneous tab tells you other informations about the current element, including when it was discovered, its mean mass (the mass per neutron) and the origin of the name.
