Jaden Gaddis Avila Chemistry 8 November 2015 Ytterbium Ytterbium is a rare element that has just recently be found. Marignac discovered it in 1850 in Ytterby, a small village in Sweden. There was noting really know about Ytterbium until the 1950s because the element was not in a very pure form; in fact when it was first found with the monazite sand, which only contains about 0.03% Ytterbium. Ytterbium is a very weird element, the metal changes with different pressures. When the metal is at its normal state it is a conductor, but when it reaches 14,000 atmospheres of pressure it turns into a semi-conductor. Sense ytterbium changes with pressure; it is used in many different technological devices. For example, many different skydivers, or …show more content…
scuba divers need a pressure detector, and many different times ytterbium is used in the makings of those devices. Ytterbium was first unearthed in 1850 in Ytterby, a small village in Sweden, by Marignac who was a Swedish chemist at this time. Ytterbium was named after the small village, when it was discovered in a small local mine. Ytterbium was first extracted from the mine, which contained monazite sand. The sand only contained about 0.03% of ytterbium. Nothing was really known about Ytterbium until the late 1950s due to its weird chemistry. Ytterbium was not really know because of its weird chemistry, it also was not able to be mass produced around this time due to the fact of the lack of technology. We still do not know very much about this metal today, due to the fact of the resent discovery, and its weird chemistry. Ytterbium is considered to be a rare element, one of the fifteen on the periodic table, but when you look into the earths crust, you see that there is twice as much as ytterbium as there is tin. But yet only 50 tons of it is produced yearly. Ytterbium is found in many different areas of the world for example, the earth’s core, but Ytterbium is also found in many different elements, such as monazite, silvery, malleable, and ductile metal. Ytterbium is a naturally occurring thorough out the earth. On the periodic table Ytterbium’s is located on the rare metals.
Its atomic number is 70, and its atomic mass is 173.04, its symbol is Yb, its melting point is 1097k, and its boiling point is 1466k. There is nothing really known about ytterbium due to it weird, for example the ytterbium when it is just sitting there is reacts with the oxygen and forms a protective oxide layer around the ytterbium. With this protective layer that surrounds the Ytterbium preserves the element from the oxygen, which breaks down the element. Ytterbium is a very soft and very malleable metal. Ytterbium is not as rare as we think it is due to the fact that it is more common than tin, but we do not use ytterbium very often due to the fact that we don’t know very much about the element. How is Ytterbium used in today’s world, on the periodic table, what are its classification is a question many people have when they hear the word Ytterbium. We know now that Ytterbium is a rare element but is twice as common as tin. That Ytterbium is a weird element due to its chemistry with the different chemical reactions with oxygen and different pressure levels. That Ytterbium was discovered in Ytterby by a chemist named Merignac, and he didn’t know much about the element, as we don’t either till this
day.
George Crum is the inventor of the Potato Chip. George was born on July 15, 1822 and passed away on July 22, 1914. George did not attend colloege nor did he have very much of an education. George's mother was Native American and his father was African American.
Ana-Mauríne Lara’s Erzulie’s Skirt positions the female body as the scene where lives are interconnected across history and as a dissertation of the human condition. Her protagonists, Micaela and Miriam, tell a story of love, struggle, and survival that echoes the historical significance of slavery and the Caribbean middle passage across time and space. Divided into several sections based on time and location, one particular period in Lara’s novel connects Micaela and Miriam’s experiences most closely with slavery as a whole. After a voyage across the Mona Strait as an attempt to escape from the conditions in the Dominican Republic, they find themselves captured, trapped in a brothel, and forced into prostitution. Many parallels can be drawn to interpret Lara’s use of the brothel as a metaphor for the slave ships used to travel across the original Middle Passage, including the comparable use of people as commodities, the specific imagery and language Lara uses, the historical narrative presented at the beginning of each section, and the larger themes in which identities were simultaneously stripped by oppression and also preserved within the context of community and spirituality.
Edward Barry Dalton is the only member of the regiment to have been the subject of a previously published work. A short biography including a selection of the surgeon’s wartime official correspondence entitled Memorial of Edward B. Dalton M.D. was complied and published as a tribute by his brother John Call Dalton shortly after his death in 1872. (John Call Dalton, Memorial of Edward B. Dalton)
Molybdenum is a transition metal. It is represented by the symbol Mo. It is a pure metal that is is silverish white in color and very hard, and has one of the highest melting points of all pure elements at 4753 °F. Its boiling point is 8382 °F. Its density is 10280 kg/m3 and its hardness is 5.5.
Beryllium has the symbol Be. In the older chemical literature, beryllium is called glucinium after the Greek word glykys meaning sweet, because of Vauquelin's initial description and observation of Beryllium. Beryllium's atomic number is 4, its atomic weight is 9.01 and in its pure metal form it melts at 1278 degrees Celsius.
This element when becoming an isotope can become radioactive due to its high activity as a metal. In its natural state it is a soft metal and it has a shiny “ wax “ like silver/white color to it, it is so soft that a knife could cut through it without a problem.
Licking the toad? A phrase most have heard before but did you know that licking the toad referenced the hallucinogenic effect certain toads had once a person literately licked it. The cause of the hallucinogenic symptoms is bufotenine. This paper will define what bufotenine is, the history behind bufotenine, signs and symptoms of bufotenine use, and bufotenine addiction treatment.
One of many samurais and shoguns there was a samurai named Shimazu Yoshihiro. He was the second son of Shimazu Takahisa. He had an older brother, Shimazu Yoshihisa. He was born on August 21st, 1535 and died August 30th, 1619. His family believed in a tradition with all their male family members had the same first name, Shimazu. He was also a member and the 17th head of the Shimazu Clan. When he was the head of the clan it was believed that his brother, Yoshihisa, had the real power of the clan.

The acclaimed soccer player Lionel Messi once stated, “You have to fight to reach your dream. You have to sacrifice and work hard for it.” This quotation emphasizes that making sacrifices is an essential ingredient in achieving a worthy goal. To reach notable desires, one must set aside something. This theme is clear in the novel Scythe, where characters make crucial sacrifices to attain their goals.
The Periodic Table of Elements is commonly used today when studying elements. This table’s history begins in ancient times when Greek scientists first started discovering different elements. Over the years, many different forms of the periodic table have been made which set the basis for the modern table we use today. This table includes over 100 elements and are arranged by groups and periods. Groups being vertical columns and periods being horizontal columns. With all of the research conducted over the years and the organization of this table, it is easy to use when needed.
Baba Yaga - The Wicked Witch of Slavic Folklore Baba Yaga is one of the most famous witches in Slavic myth and Russian folklore. Her origin is part of her mystery. The first written reference to Baba Yaga was in 1755 in Mikhail W. Lomonosov’s Russian Grammar, where she is listed amongst ancient figures from Slavic tradition. The indication is that the legend of Baba Yaga began in pre-Christian, pagan times where people were very superstitious and believed that their fates were not of their own making but at the mercy of other-worldly deities.
It is the only gem known to man that is made of a single element.
