EniG. Periodic Table of the Elements contains the basic data about the element in seven languages (Croatian, English, German, French, Italian, Spanish, and Portuguese). It shows visually the change of physical condition with the change of temperature. The language, the speed of temperature change, the exchange of elements or the scrolling of characteristics can be adjusted by configuration file.
The calculating module from the programme "Chemistry Assistant" for fast calculating the mole mass compounds has also been integrated in the Periodic Table. The programme translates texts with chemical symbols or without them, entered in input line, into mathematical terms (it can be seen as ToolTip text) and calculates them.
The periodic Table can be incorporated into presentation, the change of temperature automatically started and the programme closed. The colour of background can be adjusted to match the colour of the presentation slide.
USE OF PERIODIC TABLE
EniG. Periodic Table of the Elements can show all the names in one of seven languages. You should only click the flag in the bottom of the screen to change the language of the entire Periodic Table. In the configuration file you can set any of the languages as a default language of the Periodic Table.
The element in the Periodic Table is selected by the left click and its characteristics are changed by the right click. It is also possible to page the characteristics of the presented element by the small scroll. The unit in which a certain characteristic is expressed can be seen when the mouse is held up over the number for a few seconds.
By clicking the group number you can change it from IUPAC recommendation from 1985 into the way of writing according to Chemical Abstract Service from 1986.
By the change of temperature, depending on the physical condition of the element at the temperature concerned, the colour of the button also changes according to the key. Temperature can be changed in several ways: by entering it in the field above the thermometer, by clicking the numbers next to the scale or by clicking anywhere in the thermometer scale. The temperature display, Celsius scale (░C) or Kelvin scale (K), changes by clicking the thermometer temperature label. By the left click on the mercury reservoir, the temperature progressively grows, while by the right one it falls.
Clicking the button START the temperature changes automatically 100 K/s (░C/s) at a time, while each element will hold up in the screen for 5 seconds. The speed of temperature change and the time of holding up of an element can be changed by pressing the adjusting button (the small stop-watch next to the START button).
A small can with paint enables the users to adjust the Periodic Table to their wishes. You can also change the language concerned, the automatic start of temperature exchange and closing of the programme; you can change the initial and final temperature as well as the colours of buttons and background. The new sets of Periodic Table can be saved in configuration file and then loaded when the programme is started. The DEFAULT button gets back the original sets of programme.
The colour of the background of Periodic Table of the Elements changes so that red (R), green (G) and blue (B) components of colour are defined. To change the colour of background it is necessary, for each colour component, to enter "up" for the upward range (the value of colour is 0 at the bottom of the screen and 255 at the top), "dn" for the downward range or a number from 0 to 255.
The Periodic Table of the Elements can also have a picture as the background. The minimal size of the background picture is 800╫600 pixels. If the picture is not in the same directory where the Periodic Table is, it is necessary to enter the whole path up to the picture (e.g. c:\picture\back.jpg). As the picture covers the colour, in order to get the coloured background, without picture, the text field "Background Picture" has to be empty in configuration window.
USE OF CALCULATOR
EniG. Calculator serves for quick and simple calculating of mole mass of compounds. The chemical formula, by adding the signs of addition or multiplication, is transformed into mathematical expression where the symbols of element represent the atomic masses of the element concerned. The mathematical expression can be seen if the mouse is held up on the entry field for a few seconds. E.g.
H2SO4 becomes H*2+S+O*4 or 1.00794*2+32.066+15.9994*4
Enter the number, chemical formulae, functions and operator just as you speak.
- for indicating hydration using [+] sign CuSO4+5H2O
- leading number is correctly typed before formula: 3CO2
- it is also possible to use all types parentheses to define the chemical formula
There is an intelligent routine that translates the symbols of elements written in small letters into chemical formula. The result of the translation will be entered into the entry field and calculated, or the programme will report error. One has to be careful when writing formulae in small letters because of possibly manifold solutions (e.g. CO and Co or PO and Po). If a mathematical operation is carried out, all chemical formulae will be put in brackets. E.g. cuso4+5h2o will become (CuSO4)+5*(H2O) while h3po4 will become H3PO4.
By clicking the symbol of the element in Periodic Table it is automatically entered in the entry field. On the right button of the mouse there are some more frequently used ions and molecules.
Negative numbers are obtained by putting the sign of minus [-] before the number (e.g. 2*-3=-6).
Enter the mantissa as the positive or negative number, type E or e and then type exponent as the positive or negative number.
To perform basic mathematical operations such as addition, subtraction, or multiplication, use the following arithmetic operators:
+ Addition 8+3
- Subtraction 5-2
* Multiplication 3*3
/ Division 3/3
% Percent 20%750
^ Power 3^2
Double times (**) changes into power [^], (e.g. 2**3=2^3=8). Short key for power is CTRL+Number rising to power [^], (3CTRL2 = 3^2).
Root extraction is obtained by rising to power the number with reciprocal value of the root (1/x). Thus, for instance, the cube root of number 8 equals 8^(1/3)=2. Short key for root is CTRL+SHIFT+Number or ALT+Number (54ALT3 = cube root of a 54 or 54^(1/3)).
The button "..." will put in brackets the selected text or the whole expression in the entry field.
Functions
Every function that is supported by program can be inserted by typing its name before the number (For example log100=2 or ln(H2O)=2.89). It is necessary to indicate after "ran", either a positive number which will be the higher limit, or a negative number which will be the lower limit of generate number.

abs Returns the absolute value of a number
acos Returns the arccosine of a number

F7 key recalls the value stored in the memory.
The programme accepts both comma and full stop as decimal point.
When you finish entering your expression, press ENTER or click [=] button.
Clicking to AUTO position or SCI or FIX you can choose several display formats of a number, without the number changing (For example: 1000 = > 1.00E+03). You can directly reach by the button ".00" tools bar, with a more complete choice relating to SCI and FIX.
AUTO mode displays numbers exactly as you enter them and answers to 14 significant decimal places.
SCI mode displays a number as a mantissa - with one digit to the left of the decimal point and the user-specified number of decimal places - and the exponent. For example 5.67871E3 = 5.67871*103 = 5678.71
FIX mode displays numbers rounded to a user specified number of decimal places (default is 2)
F5 key is the switch between different number formats
