Atomic Number

The atomic number is a fundamental concept in chemistry and physics, representing the number of protons found in the nucleus of an atom. It serves as a unique identifier for each element on the periodic table, distinguishing one element from another. This numerical value determines an element's chemical properties and its placement within the periodic table. Understanding atomic numbers is crucial for comprehending various atomic phenomena, such as chemical bonding, isotopes, and nuclear reactions. In essence, atomic number forms the cornerstone of modern atomic theory, providing a systematic framework for organizing and studying the building blocks of matter.
