Organization of chemical elements in alphabetical order by their names (or symbols) doesn't tell us anything about their properties but it is useful when searching for an element. We can list elements in order of increasing atomic number but it wouldn't be a periodic table any more. The periodic table is a chart that organizes the elements by increasing atomic number and their chemical and physical properties. Rows are arranged so that elements with similar properties fall into the same vertical columns ("groups").
The lanthanides and actinides should actually be placed in the middle of the table as well, after lanthanum and actinium, but, because of their similarity to each other, they are removed from the middle to save space.
On periodni.com you can find two different sites
A small collection of tools which may help with designing and creating web pages.
The Chemical glossary contains basic information about basic terms in chemistry, physical quantities, measuring units, classes of compounds and materials and important theories and laws.
Below are several versions of the periodic table prepared for printing on A4 paper (297×210 mm)
Is chemistry in your job description or a subject in school? Here you can find a bookmark sized 'Periodic system of elements' with basic instructions on how to balance chemical reactions
Crystal systems are the easiest to understand when you hold them in your hand. Craft 3D paper models of seven basic crystal systems
or print a large educational poster for your laboratory wall (A1 paper: 841×594 mm)
These rules and style conventions could greatly assist anyone in their use and understanding of SI units
The chemistry images collection includes images of laboratory glassware and apparatus, structural formulas, crystal system, graphs, and more. You can download and use any image from my site and use it in your own work, either personal or commercial.
The Periodic Table is also available as a desktop background (wallpaper). Choose a size according to the resolution of your monitor. (Image Dimensions: 1280×887, 1024×709, 800×554.)
High resolution images (Image Dimensions: 3182×2078.)
The new Chemistry Assistant consists of several separate programs. These programs are written in pure C without MFC, and each program can be used separately as a portable application.
English-Croatian dictionary in the StarDict format (necessary for Onyx Boox, my new e-book reader) is made through conversion of a two-column dictionary file EH.txt (by Dr. Goran Igalya) in to the StarDict format. StarDict is a free, open source program with thousands of dictionaries that are easily integrated in to the main program.
The Serbian->Croatian translator is a free Visual basic program for all Windows platforms that can translate texts, subtitles for movies or whole web pages from Serbian to Croatian (sr2hr dictionary contains over 65 000 words).
A small collection of my old, but fully functional programs written in Visual Basic 6.0.
Here, I provide the abstract of my scientific articles, which has been published in peer reviewed scientifc journals.
written for students of graduate and undergraduate studies at the Faculty of Chemistry and Technology.
