Dmitri Mendeleev

Alyssa Eaves Professor David Bergbreiter CHEM 227 22 November 2014 Dmitri Mendeleev: A Biography Today in American classrooms, the name Dmitri Mendeleev conjures up the sole image of a periodic table, secure and immutable with all its ordered numbers and letters marching along in dependable patterns. More than one hundred years ago in Imperial Russia, the name Dmitri Mendeleev would call to mind séance scandals, economic tariffs, hot air balloon rides, a nationwide push for the metric system, bigotry charges, and student protests. This was the Mendeleev that Russia knew and (mostly) loved. The periodic table was just a particularly prescient project tucked away in an introductory chemistry textbook, widely known to the scientific community…

Dmitri Mendeleev said,“There is nothing in this world that I fear to say.” Dmitri Mendeleev was a very intelligent man who strives for the best. Dmitri is the first person who created the periodic table and published it. He created and discovered it in the most interesting way. Even though he struggled through his childhood, he managed to have a good life. He also achieved a lot of goals after the periodic table. Dmitri was born in Tobolsk, Siberia on February 7, 1834. He had 14 siblings, and…

Purpose: Utilizing our comprehension of the arrangement of the elements in the periodic table (the way elements with common traits are grouped together), we will determine the name and location of each unknown element by clustering said elements with other known elements that they share the most characteristics with. In this lab we will momentarily fill the shoes of the Russian chemist Dmitri Mendeleev, who was the first to observe the patterns between elements arranged according to their…

great pride in finding out about the Deep-Sea Deposits and how the Coral Reef formed (Sir John Murray | biography). This gave him the driving passion to continue to search the ocean for many years to come. During this time (1870-1910) some of the biggest discoveries and advancements in science happened, such as when Dmitri Mendeleev invented the periodic table. Since a boy Mendeleev had been enthusiastic about chemistry and was determined to make a major discovery in it. Originally he had gone…

Dmitri Mendeleev is the creator of the first periodic table. Dmitri was born on February 8, 1834, in Verkhnie Aremzyani, Russia to a family of 16. His dad was a teacher, who went blind. His mom ran a glass factory. At the age of 13, his dad died. Dmitri decided to go to college when he was 16. He applied to the same college his dad went to, and was accepted partially because they knew his dad. He studied to become a teacher there. When he was 20, he graduated at the top of his class. Then,…

religion has set in the model of the universe. Dmitri Mendeleev had to work hard to break past the boundaries of society in order to apply his knowledge to come up with his scientific breakthrough of the periodic table. By asserting himself using the strategies he had learned from trial-and-error that enabled Mendeleev to strive for his conclusion of the perfect table. Mendeleev saw that many people failed to understand chemistry, and correlated this to the lack of clear system for classifying…

Salbutamol Discovery Chiral chemistry was introduced in 1848 by French chemist and biologist, Louis Pasteur. He discovered this new branch of chemistry after he separated two isomers of ammonium tartate (1). This paved the way for several progressions in the pharmaceutical industry. Although it took approximately a century for scientists to use chiral compounds as effective drugs, they have played a remarkable role in the life of plants and animals (1). The credit for discovering the chiral…

How are elements useful for a particular use? An element is made from one type of atom and this article is about the element Scandium. Scandium was discovered in the year 1879 by Scientist Lars Fredrik Nilson in the university of Uppsala. The origin of the name comes from the word Scandia, which is the latin name for Scandinavia. This element belongs to group 3 which consists of transition metals and Scandium shares this group with the element Yttrium. There are 4 groups in the periodic table…

solubility of a substance is the amount of that substance that will dissolve in a given amount of solvent. Solubility is a quantitative term. Solubilities very enormously. The terms soluble and insoluble are relative. A substance is said to be soluble if more than 0.1 g of that substance dissolves in 100 mL solvent. If less than 0.1 g dissolved in 100 mL solvent, the substance is said to be insoluble or, more exactly, sparingly soluble. The terms miscible and immiscible may be encountered when…

scientists which helped aid the making of the periodic table. Of those, the German chemist Robert Bunsen, after experiencing an unfortunate incident with arsenic, he began his study of natural explosives, like volcanoes. He studied how the geyser exerted pressure and how that pressure also built up. Kean then talks about how Bunsen invented the spectroscope which allowed scientists to look inside compounds without boiling them or putting them in acid. Towards the end of the chapter, Kean…
