About Dmitri Mendeleev
Dmitri Ivanovich Mendeleev, a key figure in the development of the periodic table, was born on February 8, 1834, in Tobolsk, Russia, and died on February 2, 1907, in Saint Petersburg, Russia.
He was the youngest of 14 siblings, born into a family that highly valued education. After the death of his father and the destruction of his mother's factory by fire, Mendeleev's mother moved the family to Saint Petersburg, where he attended the Main Pedagogical Institute. After graduating, Mendeleev worked and lived in several places, including Heidelberg, Germany, where he interacted with several renowned chemists. He later returned to Saint Petersburg and worked at Saint Petersburg State University and the Bureau of Weights and Measures.
The curiosity and tenacity of Mendeleev were crucial in driving his scientific achievements. From early in his career, he was captivated by the nature of chemical elements and the underlying principles that governed their behavior. This drive eventually culminated in his development of the Periodic Table.
Dmitri Mendeleev's Discoveries
Mendeleev is best known for his discovery of the Periodic Law and the creation of a periodic table of elements. The table organized elements by atomic weight, where they fell into vertical columns if grouped by their chemical properties. This was an incredibly important discovery as it allowed scientists to see the relationships between various elements, predict the properties of elements yet to be discovered, and understand the fundamentals of chemical behavior.
The process wasn't without its challenges. At first, Mendeleev had gaps in the table, but instead of seeing these as problems, he accurately predicted the properties and atomic weights of elements that would fill these gaps. These elements were discovered later, affirming the validity of his Periodic Law.
Dmitri Mendeleev's Key Achievements
Mendeleev's key achievement is undoubtedly his Periodic Law and the construction of the Periodic Table. He also made significant contributions to various other fields, including the determination of the nature of solutions and the study of the expansion of liquids with heat. In addition to his scientific work, Mendeleev was also involved in developing the first oil refinery in Russia and establishing a system of standardized weights and measures.
Dmitri Mendeleev's Formulas
While Mendeleev did not formulate any specific mathematical formulas, the principles of his Periodic Law can be seen as a fundamental formula in the field of chemistry. This law can be expressed as follows:
Where:
- Properties of elements: This refers to the various properties of elements such as their reactivity, electron affinity, and atomic size.
- f(Atomic weight): This implies that the properties of elements are a function of their atomic weight.
