Relative atomic masses are expressed with five significant figures. For elements that have no stable nuclides, the value enclosed in brackets indicates the mass number of the longest-lived isotope of the element. However three such elements (thorium, protactinium and uranium) do have a characteristic terrestrial isotopic composition, and for these an atomic weight is tabulated (Atomic Weights of the Elements 2007, Pure Appl. Chem., Vol. 81, No. 11, (2009) 2131-2156). Two new elements added to the Periodic Table!

Why is the periodic table shaped like it is?

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 version of the periodic table

  • EniG. Periodic table of the elements - a very attractive periodic table, available in six languages (German, English, French, Croatian, Italian, and Spanish) and twelve temperatures (ITS-90), completely designed in CSS.
  • ASCII Periodic table of the elements - a periodic table especially made for browsers with slow (or expensive) connections (such as a mobile phone users) or for purely text-based browsers like Lynx.

C Programs

The new Chemistry Assistant consists of several separate programs. These programs are written in pure C without MFC (for faster execution speed and smaller size), and each program can be used separately as a portable application.

 

Part I. Calculator for Chemists

Calculator for Chemists

is a small but powerful scientific expression calculator which supports many scientific functions (sin, cos, log, power, root, memory, ...), normal and inverse. All of the calculations can be printed or saved and recalled again. (Calculator for Chemist Online Help)

 

Part II. Solution Calculator

Solution Calculator

is a useful tool which allows you to calculate how many solid chemicals or stock solutions you will need to prepare the desired solution. The program provides lab-ready directions on how to prepare the desired solution. (Solution Calculator Online Help)

 

Part III. Unit & Number Converter (New on periodni.com)

Unit and Number Converter

is a program that will convert most popular units of length, mass, volume, temperature, pressure, energy and many others. It also includes the ability to create custom conversions for anything you want (you can create your own custom units). This simple tool allows you to convert the number from one numeral system into another (for example, from binary into decimal or Roman numeral system). (Unit & Number Converter Online Help)

 
 

Dictionaries and Translators

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. The most important thing in the program are the dictionary files which grow with each read (translated) book (sr2hr dictionary contains over 65 000 words).

 

Visual Basic Programs

A small collection of my old, but fully functional programs written in Visual Basic 6.0.

  • EniG. Periodic Table of the Elements - contains the basic data about the element in 7 languages; it shows visually the change of physical condition with the change of temperature.
  • EniG. Chemistry Assistant - VisualBasic scientific calculator for fast calculations of molecular weight, quadratic equations, quantity of chemicals for preparations of solutions and statistic analysis of experimental data.
  • EniG. Change Code Page - converts web pages between different standards, eg. from windows-1250 in to ISO-8859-2 or UTF-8.
