The atomic number of an element is the number of protons found in the nucleus of an atom, which uniquely identifies the element and determines its position in the periodic table. It also equals the number of electrons in a neutral atom, influencing the chemical properties and reactivity of the element.

The periodic table is a comprehensive chart that organizes all known chemical elements based on their atomic number, electron configuration, and recurring chemical properties. It serves as a fundamental tool in chemistry, enabling scientists to understand element relationships, predict chemical reactions, and discover new elements.
