Kalzium
Science
Description:

Kalzium is an interactive application which shows you information about the periodic table of the elements. Kalzium can be used as an as an information database.
Kalzium has already some nice features, however but there remains things to add. As Kalzium has been included in KDE 3.1+, we still work steadily to add in some new enhancements, while hopefully making it as fast and usefull as possible. You can help us by testing it or make proposals for new features or a better design.

Changelog:

Hydrogen:
From this release on standalone releases will be named after the elements. This is the first release and is called Hydrogen. The next will be called Helium and so on.

md5sum of this release: 85bb8a313291affbcc53c565dbbae44d

Compared to the Kalzium known from KDE 3.4 we changed:

new design of the table
sidebar for calculation of molecule weight and for the timeline
a glossary explaining the main chemical words
view properties per gradient
new data properties
half-life period of isotopes
more isotopes added
basic information about crystal structures of metals
electroaffinity
name origin: Where does a name of an element come from?
More Radii
Atomic Radius
Covalent Radius
van der Waals Radius
Ionic Radius (for one charge only)
More elements do have information about ionization energies, especially the higher energies (3rd to 6th)

wouldn't it be nice if kalzium had a integrated drawing tool?

as far as i know, there's no nice, feature rich chem. drawing tool for linux. or to be more precise, none of the linux tools nicely integrates into kde and uses its "framework"

on another note, wouldn't it make sense to move kalzium and eg kstars out of kde-edu and form a new package like kde-sci?

Thanks

If you tell me what you would like to see chances are good that I will add it. Do you have any ideas?

I use the version which comes with KDE 3.2, it's v0.9.3 and there are all the features I need therefore I don't miss any feature.

Does Kalzium have a feature to show the position of the elements in the reactivity series? That could be a worthwhile feature.

You mean like on this page? Do you have the date for all elements?

Yes, that's what I mean but I don't have the data for all the elements. If you can't find the data either, you might be able to work most of it out from:
http://www.nelsonthornes.com/secondary/science/scinet/scinet/reaction/react/periodic.htm

and the more complete list at:
http://www.chemos.co.uk/Reactivity.htm

Francium (Fr) is the most reactive element of them all, as I understand it.
