ACKNOWLEDGEMENT

I would like to convey my heartful thanks to Mr. Susan Pal (Computer Science) who always gave valuable suggestions & guidance for completion of my project. He helped me to understand &remember important details of the project. My project has been a success only because of his guidance.I am especially indented & I am also beholden to my friends. And finally I thank to the members of my family for their support & encouragement.

The periodic table is a tabular arrangement of the chemical elements, organized on the basis of their atomic number (number of protons in the nucleus), electron configurations, and

4

recurring chemical properties. Elements are presented in order of increasing atomic number, which is typically listed with the chemical symbol in each box. The standard form of the table consists of a grid of elements laid out in 18 Groups and 7 Periods, with a double row of elements below that. The table can also be deconstructed into four rectangular blocks: the s-block to the left, the p-block to the right, the d-block in the middle, and the f-block below that.

This program is used in scientific data base projects to know the different physical and chemical properties of an element.

The first 98 elements exist naturally although some are found only in trace amounts and were synthesized in laboratories before being found in nature. Elements with atomic numbers from 99 to 111 have only been synthesized, or claimed to be so, in laboratories.

For creating this project I have taken help from Mr. S. Pal our computer sir and also from our text book written by Sumita Arora.For creating this project I have gone through the following websites.

a) www.c++blogspot.com b) www.cplusplus.com c) www.icbse.com d) projects .icbse.com/subject/cpp e) projects.icbse.com

These are very helpful websites as they are having sample project.
