What is the modern periodic law, and how does it differ from Mendeleev's periodic law?
1 Answer
The modern periodic law states that the physical and chemical properties of elements are periodic functions of their atomic numbers. It differs from Mendeleev's law, which was based on atomic masses. The modern law:
1. Uses atomic number as the basis for arrangement
2. Explains anomalies in Mendeleev's table (e.g., positioning of isotopes)
3. Provides a more accurate prediction of element properties
4. Accommodates noble gases and newly discovered elements more effectively
