The Periodic Table organizes elements systematically based on atomic numbers and properties, illustrating trends in behavior and characteristics. Historical frameworks by Dobereiner, Newlands, and Mendeleev laid the groundwork for the modern classification, which is enhanced by periodicity in properties such as atomic size and electronegativity. The modern table's structure reveals relationships across periods and groups, providing essential insights into element behavior and predictable properties.

Elements are arranged in the Periodic Table by atomic number and properties.
Historical classifications contributed to the development of the modern Periodic Table.
Properties of elements show periodic trends based on their position in the table.
An arrangement based on increasing atomic mass, placing elements with similar properties in the same group with gaps for undiscovered elements.
States that the properties of elements are a periodic function of their atomic numbers, correcting anomalies in Mendeleev's table.
Refers to recurring trends in element properties across periods and groups in the Periodic Table.
