The question asks for the fundamental property upon which the Modern Periodic Table is organized.
Modern Periodic Table Basis
The Modern Periodic Table arranges elements based on their Atomic Number. This was a significant shift from earlier periodic tables, like Mendeleev's, which were based on atomic mass.
Key Points:
- Atomic Number (Z): Represents the number of protons in an atom's nucleus. It uniquely identifies an element.
- Periodic Law (Modern): States that the physical and chemical properties of elements are periodic functions of their atomic numbers.
- Significance: Organizing by atomic number correctly addresses issues related to isotopes and explains the observed periodicity in element properties more accurately than atomic mass.
Therefore, the arrangement of elements in the Modern Periodic Table directly follows the increasing order of their atomic numbers.
