What is Periodic Table of Elements?

The Periodic Table of Elements is an important scientific tool that is used to organize and display the known chemical elements. It was first developed by Dmitri Mendeleev in 1869, and it has since become one of the most widely recognized symbols in science. The table arranges all known elements into rows and columns based on their atomic number, electron configuration, and recurring chemical properties. This arrangement allows scientists to easily identify how different elements interact with each other as well as predict new elements that might exist beyond what we currently know.Because of its organization and simplicity, the Periodic Table has been incredibly useful for both scientists and students alike. For example, it can be used to look up information about an element such as its symbol, atomic number, atomic weight, boiling point or melting point. It also provides insight into how different elements form compounds with each other which can help chemists better understand reactivity between them when creating products like plastics or medicines. Additionally, it’s a great way for students to learn about basic chemistry concepts because they can quickly access information about any given element without having to memorize long lists of facts or formulas. Overall, the Periodic Table of Elements is a powerful resource that has helped shape our understanding of chemistry over time and continues to aid us in research today.
