![]() When the elements are arranged in this fashion, you can observe periodicity in their properties, according to similarities in electronic configuration. They are arranged in a grid pattern with a total of 18 columns called ‘groups’ and 7 rows called ‘periods’. Out of the need to classify and identify the relations between these different atoms, a periodic table of elements was created, in which all the chemical elements were arranged according to the atomic number. There are as many as 92 different naturally occurring atoms of different kinds which bond with each other to form the complex forms of matter all around us. So is everything made up of the same kind of atoms? No. Not only do we know all about atoms today, but stellar physics has also solved the mystery of how these atoms were created. ![]() In the 20th century, that task was accomplished and now we know that everything is made up of atoms. Since ancient times, people have occupied themselves with the task of finding the ultimate building blocks of matter. In this ScienceStruck article, you will find an explanation of what is the periodic table used for and why having it hung in chemistry labs and classrooms is necessary. ![]() It is one of the most important reference tables in science which lists all the types of atoms which make our physical world. 1999‑2023 - All Rights Reserved.On entering your chemistry lab, you are bound to find a big chart labeled as ‘Periodic Table of Elements’ hung over the wall for reference.
