Dmitri Mendeleiev, O Pai da Tabela Periódica

Summary

Dmitri Ivanovich Mendeleev, born in 1834 in Russia, was the youngest of 14 surviving children. After his father's death, Mendeleev's mother moved the family to St. Petersburg, where he studied chemistry. His groundbreaking work led to the creation of the periodic table, organizing elements by atomic weight. Mendeleev's insights were so powerful that he even predicted the discovery of unknown elements, which were later confirmed. He became a respected professor and received numerous honors for his work. Mendeleev passed away in 1907, but his legacy lives on, with element 101 named in his honor.

Takeaways

• 😀 Dmitri Ivanovich Mendeleev was born in 1834 in Russia and was the youngest of 14 surviving children.
• 😀 Mendeleev lost his father at the age of 13, leading his mother to operate a small glass factory, which later burned down.
• 😀 After the fire, Mendeleev's mother took him to Saint Petersburg, where he enrolled in the local institute.
• 😀 Mendeleev lost his mother shortly after and graduated in 1855, later obtaining his master's degree and starting organic chemistry research.
• 😀 He received a government-funded scholarship to study abroad for two years at the University of Heidelberg in Germany.
• 😀 In Heidelberg, instead of collaborating with prominent chemists, Mendeleev set up a laboratory in his apartment.
• 😀 Mendeleev returned to Saint Petersburg and became a professor at the Technological Institute in 1862.
• 😀 He married Feodosiia Latyva, with whom he had two children, before divorcing after nearly 20 years of marriage.
• 😀 Mendeleev remarried Anna Popova and had four more children. In 1875, he defended his Ph.D. thesis and became a professor of chemical technology.
• 😀 In 1869, Mendeleev began writing his textbook on chemistry, where he proposed the periodic law and constructed a table of elements based on atomic weights.
• 😀 Mendeleev's periodic table was groundbreaking, predicting the properties of unknown elements, earning him international recognition. The element with atomic number 101 was named 'Mendelevium' in his honor.
