So what is the Periodic Table?The Periodic Table is the base foundation to science. In short, to understand science one must have at least a basic knowledge about the Periodic Table.To the ignorant, it’s just 100-plus numbered boxes, each containing one, two or three letters, arranged with an odd, skewed symmetry.To a person of science, however, the periodic table reveals the organizing principles of matter.The structure of the table reflects the electronic structure of the elements, and hence their chemical properties and behavior. Perhaps it would be more appropriate to say that all of science starts with the periodic table.

The periodic table was discovered by Dmitri Ivanovich Mendeleev in 1869.What has always struck me is how Dmitri Mendeleev found a way to arrange the elements known at that time into a meaningful and predictive periodic table, and that too he accomplished it without any knowledge of the structure of atoms.For those who don’t know, there are no atomic numbers on Mendeleev’s periodic table, only atomic weights and the groupings of elements based on their known properties.More than 30 years would pass before J. J. Thomson discovered the Electron and suggested that the electronic configuration of atoms might account for the periodicity of the elements, and almost 50 years before atomic numbers were recognized as the basis for ordering the elements.

Mendeleev’s brilliant insight propelled chemistry into the 21st century. New elements were discovered that filled in the holes Mendeleev left in his table, and their atomic weights and chemical properties corresponded with remarkable accuracy to Mendeleev’s predictions. And as the revolution in science and physics unfolded in the early decades of the 21st century, most of the discoveries about the structure of atoms, their properties, and how they interact with each other made perfect sense in light of the periodic table.Till date, the periodic table still continues to grow with new elements still being discovered and added to fit in the table.Here is a list of all the Elements in the Periodic Table:
