Questions & Answers
Q: What is Mendeleev best known for?
Mendeleev is best known for creating the original periodic table of elements through his innovative Periodic Law, which arranged elements by similar properties and atomic weight.
Q: How did Mendeleev predict the existence of undiscovered elements?
Mendeleev noticed gaps in the periodic table and theorized that these gaps represented undiscovered elements. He accurately predicted the properties of these elements, and eventually, seven out of ten of his predictions were discovered.
Q: What were Mendeleev's other contributions to science?
Mendeleev played a significant role in the study of petroleum and helped establish Russia's first oil refinery. He also became the Director of the Bureau of Weights and Measures and set the official standards for the production of vodka in Russia.
Q: Did Mendeleev receive a Nobel prize for his work?
Mendeleev was nominated for a Nobel prize for his Periodic Law, but he was denied the prize due to a conflict with an influential Swedish chemist, Svante Arrhenius, who lobbied against him on the Nobel committee.
Summary & Key Takeaways
-
Dmitri Mendeleev was born in Siberia in 1834 and went on to become a professor in Saint Petersburg. Despite his humble beginnings and surviving tuberculosis, Mendeleev made significant contributions to the field of science.
-
Between 1868 and 1870, Mendeleev developed the Periodic Law, which stated that elements with similar properties and atomic weight would appear periodically in rows. This led to the creation of the rudimentary periodic table of elements.
-
Mendeleev not only arranged elements by atomic weight but also predicted the existence and properties of undiscovered elements, with seven out of ten of his predictions eventually being discovered.
