Dmitri Mendeleev contribution to chemistry

Answer 1

Dmitri Mendeleev's most significant contribution to chemistry was the development of the periodic table of elements. In the 1860s, Mendeleev observed patterns in the properties of elements and arranged them into a table based on atomic weight. He left gaps in the table for elements that were yet to be discovered and accurately predicted the properties of these missing elements. His periodic table provided a systematic framework for organizing elements and became a fundamental tool in chemistry, allowing scientists to understand relationships between elements and make predictions about their behavior. Mendeleev's work laid the foundation for the modern understanding of chemistry and remains one of the most important contributions in the field.
