How is the periodic table organized?

The periodic table is organized based on the atomic number, which represents the number of protons in an atom's nucleus. Elements are arranged in order of increasing atomic number from left to right and top to bottom. The table is divided into rows called periods and columns called groups. Each period represents a different energy level of the elements, while each group shares similar chemical properties. Elements on the left side of the periodic table are metals, while those on the right are nonmetals. The periodic table allows scientists to easily identify and study the properties of different elements and their relationships with each other.
