What is a Periodic Table and what is it used for in science and our everyday lives? On entering the chemistry laboratory at Mercer University, for Science 100 a large colorful chart displaying rows and columns of cells, was hanging over the chalkboard. I immediately felt a bit intimidated and my heart began racing. I questioned myself as to what am I about to experience? Moving closer to examine the chart, I felt as if the bright colors on the chart were generating warmth (energy) and that chart was an exhibit of the Periodic Table.

For years, different people ventured to group elements by their chemical traits. However, Dmitri Ivanovich Mendeleyev (1834-1907) a Russian chemist is first to devise a periodic table of elements. He is often referred to as the “father” of the periodic table. His table was based on the atomic weight of elements. Furthermore, he recognized that there were many elements that occurred periodically that shared similar properties. This led Mendeleyev to formulate the periodic table of elements.

The periodic table consists of over 117 elements. It is a table in which the chemical elements are arranged in order of increasing atomic numbers. There are many elements present in the atmosphere and the periodic table helps us to understand the various properties, abbreviations and names of the elements present in nature (buzzle.com). Elements with similar properties are arranged in the same column called a group, and elements with…
