उत्तर
Moseley
Explanation:
- Dobereiner, Newlands, and Mendeleev all classified elements based on their atomic masses, which was the scientific consensus during their respective eras.
- Moseley, however, established the modern periodic law by demonstrating that the fundamental property of an element is its atomic number (the number of protons), not its atomic mass, and he organised the periodic table accordingly.
