What Is the Periodic Table?
Your complete guide to understanding the foundation of chemistry — built for NEET, JEE, CBSE, and ICSE students
The periodic table is a systematic, organized chart of all 118 known chemical elements, arranged in order of increasing atomic number. First proposed by Russian chemist Dmitri Mendeleev in 1869, the modern periodic table arranges elements so that those with similar chemical properties fall in the same vertical column (called a group), while horizontal rows (called periods) reflect elements with the same number of electron shells.
Each element is characterized by its symbol (1–2 letter abbreviation), atomic number (number of protons), atomic mass (average mass in amu), electron configuration, and valency (bonding capacity). The periodic table is the single most important reference tool in chemistry — understanding it is essential for every student of science.
The Interactive Periodic Table Tool on SarkariWings is designed to make chemistry learning visual, interactive, and effective. Whether you're revising for NEET, preparing for JEE, studying for Class 11 or Class 12 board exams, or just beginning your chemistry journey in Class 9, this tool gives you everything you need.
