The periodic table is one of the most important tools in chemistry, organizing all known chemical elements based on their atomic number. From hydrogen, the lightest element, to uranium, the heaviest naturally occurring element, the periodic table is essential for understanding how matter behaves.
Each element has unique properties, and many elements combine to form compounds that make up everything around us. Scientists use the periodic table to predict how elements will react with one another, helping us to understand the building blocks of matter.
