The information dialog

The information dialog is accessed by clicking with the left 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.

Overview

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


Kalzium information dialog

Picture

The Picture tab displays a picture of the element when available.


Kalzium information dialog

Bohr Orbitals

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

Chemical Data

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.

Mass

The mass of this isotope.

Neutrons

The number of neutrons this isotope has.

Percentage

The percentage of atoms occuring that are of this isotope type. Also called abundance.

Half-life period

Only unstable isotopes have a half-life period. It is defined as the time in which half the isotopes decay.

Energy and Mode of 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.

Spin and parity

The spin of the nucleus and its parity.

Magnetic Moment

The magnetic dipolemoment of the nucleus. Measured in units of the nuclear magneton.


Kalzium information dialog

Miscellaneous

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


Kalzium information dialog

Chemical Energies

The Energies tab tells you about different energy facts related to the element.

Spectrum

If Kalzium has information about the emission-spectrum of the current element, this page will display it at the top. The displayed wavelength increases from left to right. The wavelength between 380 nanometer (nm) and 780 nm have the colors of the visual light spectrum. For example, 550 nm is the color green.

There are two ways to zoom into the spectrum. With the spinboxes displayed right below the spectrum, the first and the last wavelength of the spectrum are defined. Furthermore, you can hold the left mouse button pressed whilst moving the mouse cursor over the spectrum. You will see the area in which Kalzium would zoom into marked with a white line. Once you release the left mouse button, Kalzium will zoom into the selected area.

At the bottom of the page is the Export Spectrum as Image-button. With it you can save the current spectrum as an image file.

To zoom out of the view by 10% press the right mouse button while the mouse is inside the spectrum.
