The Periodic Table organizes chemical elements by atomic number, revealing patterns in properties and reactivity. Periods show electron shell filling, while groups indicate shared valence electrons. Dmitri Mendeleev's work on element arrangement by atomic mass led to the modern table, which is essential for understanding chemical behaviors and is applied in various industries, from pharmaceuticals to aerospace.
