SUMMARY
Scientists like Dmitri Mendeleev determined atomic masses through experimental methods based on the Law of Multiple Proportions. This principle states that when elements combine, they do so in ratios of small whole numbers, allowing for the calculation of relative atomic masses from the amounts of reagents used in chemical reactions. Early chemists utilized these ratios to establish a systematic approach to listing elements according to their atomic masses, which was foundational for the development of the periodic table.
