Whose Periodic Law was modified and adopted the Atomic number as the basis of Modern Periodic Table?
Periodic Law Modification and Atomic Number
Dmitri Mendeleev played a crucial role in developing the periodic system. His initial periodic law was based on arranging elements according to their increasing atomic masses.
- Mendeleev's Periodic Law: The properties of elements are a periodic function of their atomic masses.
- Basis: Atomic Mass
Subsequent scientific discoveries, particularly Henry Moseley's work in the early 20th century, demonstrated that the atomic number (number of protons in the nucleus) is the more fundamental property that governs an element's behavior.
This led to the modification of Mendeleev's original law. The Modern Periodic Law is based on atomic number, establishing the structure of the current periodic table. Because Mendeleev's original concept was the foundation that was later revised and adopted using atomic number, his work is linked to this modification for the Modern Periodic Table.
