Periodic table

Lithium is an element with the atomic number 3 on the periodic table. Its atomic symbol is Li. Lithium belongs in the most reactive group on the periodic table which is called alkali metal. Lithium under standard conditions is the lightest metal it is also one of the least dense solids. Lithium has an atomic mass of 6.94 and density of 0.534. Lithium is a soft silver white looking metal. Lithium melts at 357 degrees and boils at a temper of 2426 degrees. Thanks to lithium's ability to reach…

only he concluded that elements should be classified by its atomic number. He stated that the atomic number must be the number of positive charges on the nucleus, Mosely helped to refine the order of elements in the periodic table and this revealed the flaws in the periodic table. It also helped scientist to utilize the technique of X-ray spectroscopy to analysis and identify new elements. Glenn Theodore Seaborg (1912-1999) In 1941, Seaborg had discovered the first transuranium element…

Kean explores each of the elements on the periodic table. The Disappearing Spoon focusses on the history of the Periodic Table by telling stories that show how each element affected the scientists that discovered it. For each element, Kean supplies an extensive backstory for its foundation, the common (or uncommon) uses of the element and other useful factoids about the matter. The author begins the novel with a physical description of the Periodic Table as a whole; he discusses the names of the…

Gallium is one of those elements that is used in industry every day. Gallium was discovered in Paris at the private laboratory of Paul-Emile Lecoq de Boisbaudran (1831-1912) at 3 a.m. on August, 1875. He observed a new violet line in the atomic spectrum of some zinc he had extracted from a sample of zinc blende ore (ZnS) from the Pyrenees. He knew it meant that an unknown element was present. Gallium comes from Gallia, the Latin name for France. Gallium also has origins in the Latin word Gallus.…

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 since he had such a big family it was hard for…

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.…

this book about the periodic table and how each element was discovered and how it affected each scientist when they discovered it. The story shows scientist such as Maria Goeppert, Dimitri Mendeleev, Robert Bunsen, Fritz Harbor, William Crookes, and many more. However, in this essay I am going to write about Dimitri Mendeleev, Robert Bunsen, and Fritz Haber. Dimitri Mendeleev is a very important scientist when it come to the periodic table, he is known as the, “creator” of the table. Mendeleev…

Bromine was discovered in 1826 by a French chemist by the name of Antoine-Jérôme Balard. It contains a molar mass of 79.904 grams per mole (g/mol). Bromine falls within group 7 of the periodic table and is a halogen. Its atomic number is 35 and is one of seven diatomic elements. Bromine is one of two elements that holds the natural state of liquid. I chose bromine for my independent paper because of many other elements I knew little to none about, I have never heard of bromine and was…

Eric Scerri starts his book off by talking about a few people and describing what they did, and how they contributed to chemistry/periodic table. One person being John Dalton who developed what is known to be modern atomic theory. Another being…

theory about periodic trends. We put these 3 metals through different tests to show why elements in similar group and period react differently. The purpose for this lab is to test the idea of patterns in the periodic trend, and if elements in similar group or similar period react differently due to the trend that they follow. If two elements in the same group or family are to be tested, one of the element reactivity will be slightly different from the other. This is the work of the periodic…
