periodical table of elements

The periodic table of elements is a organized chart that groups all known chemical elements based on their properties and atomic structure. Each element has a unique number of protons, called the atomic number. The table arranges elements in rows (periods) and columns (groups) to highlight patterns in their behavior, such as reactivity and bonding. This organization helps scientists predict how elements will interact, understand their characteristics, and discover new elements. Overall, the periodic table is a fundamental tool that reflects the relationships and structure of matter at the atomic level.
