Dmitri Mendeleev

Dmitri Ivanovich Mendeleyev, born on February 8, 1834, was believed to be the youngest of 14 children. His father, Ivan Pavlovich Mendeleyev was a teacher at a local gymnasium. Around the time Dmitri was born, his father went blind and later died in 1847. Consequently to support the family, his mother Mariya Dmitriyevna Kornileva began working at a small glass factory in a nearby town, and eventually started managing it. On December of 1848, the factory burned down, and the family moved to St.…

Shinya Yamanaka is a very successful biologist that is an expert in STEM cell research. He has recently become a frontrunner with the discoveries he has made in the field. To understand Yamanaka’s life, it is important to look at his early life, his accomplishments, and the significance/implications of these discoveries for the future. Shinya Yamanaka was a very well educated man that worked hard to get the positions he desired despite several setbacks. Yamanaka was born on September 4, 1962 in…

Dalton Ellis Adv. Chemistry Mr. Lawson 6th 1/05/16 Reading Assignment I choose The Disappearing Spoon, by Sam Kean because I read short reviews on all the books on the reading list, and this one seemed the most interesting. After doing some research on the boom I found that it had great reviews online, and was one of the top ten most recommended books in the chemistry genre. This book caught my attention because it gave a brief history of many of the elements, and I was keen to learn how to…

Demitri Mendeleeve was a Russian chemist who invented the first periodic table in 1869. The periodic table he made was very different from the modern day periodic table we know today. Henry Moseley updated Mendeleev's version of the periodic table in 1915. This is more like the periodic table that we know and use today. The only difference is that there has been many more elements added. Mendeleeve also had predicted a lot of the characteristics and properties of elements that would fill up…

properties the elements share. Like Mendeleev, we had made connections toward the creation of the periodic table. When finding the unknown elements we used other known elements as guides and looked for similar properties. Like the Periodic Table today, it is organized through similar properties of each element and categorized in groups. Dimitri Mendeleev was a chemist from Russia who lived in poverty and was the only one of seventeen siblings to attend school. Mendeleev then created the first…

Introduction: Dmitri Mendeleev is accredited with the creation of the periodic table but in reality, many scientists have contributed in the years leading up to the production. Before people could even write they knew some of the elements that are on the periodic table. The elements include silver, gold, copper, tin, lead, and mercury (substances that could not be broken down chemically). Not until 1649 did a man by the name of Hennig Brand discover phosphorous (an element) through…

table of elements contains about 118 elements, and there are also many trends in the periodic table, such as ionization energy, electronegativity, and many other trends. When Dmitri Mendeleev created the periodic table, not all of the elements were present. It took many other scientists to discover the other elements. Mendeleev started to notice the patterns in the properties and atomic weights of halogens, alkali metals, and alkaline metals. He created a card for each of the 63 known elements…

In the cold Siberian winter of 1834, Dmitri Mendeleev was brought into this world, and his contributions to science would last forever. His aspirations and interests would shine as bright as the glass his family created, but the dirt and grime of that factory was not where this bright mind belonged. Dmitri started off slow, but in time was able to create one of the most memorable and iconic symbols and tools used in the scientific world, the periodic table. In his time in science, it took not…

modern periodic table there was the periodic table that Dmitri Mendeleev constructed. There are many differences and similarities between the Modern Periodic Table and Mendeleev’s Periodic Table. Just for example, the modern periodic table arranges elements in order of increasing atomic number. Mendeleev’s ordered them based upon increasing atomic weight. Another difference is that the modern periodic table has some elements that Mendeleev had not found. One of these family of elements are the…

Communism and its effect on Shostakovich The music of Dimitri Shostakovich has been steeped in political turmoil for its entire existence. Shostakovich was one of many notable composers to arise in the twentieth century and he and his music were both handled very carefully by the Communist Party in Russia at the time. While Shostakovich had a deep love of his homeland, often criticising composers who left after the revolution, he was also very critical of the social injustice present in their…
