Free Essays on The Characteristics Of The Metaphysical Poets

What are the main characteristics of the metaphysical poets? (With reference to ‘The Flea’, ‘The Apparition’ and ‘To His Coy Mistress’) A characteristic is a distinguishing quality, attribute or trait applied to something to make it similar to something else. The two metaphysical poets that we will consider are John Donne and Andrew Marvell. Although these two poets were both writtig in the 17th Century both had completely different upbringings and experiences throughout their lives. Andrew Marvell was born in Yorkshire, on March 31st 1621 to the Rev. Andrew Marvell, and his wife Anne. When Marvell was three years of age, the family moved to Hull, where Rev. Marvell became lecturer in Holy Trinity Church. He was educated at the Hull Grammar School, and in 1633 he matriculated as a Sizar of Trinity College, Cambridge. Two poems by Marvell, one in Greek, one in Latin, were printed in the â€Å"Musa Cantabrigiensis† in 1637. In 1638 Marvell was admitted a Scholar of Trinity College, and took his B.A. degree in the same year. A few days after receiving his scholarship, Marvell's mother died. He remained a few more years in residence, leaving Cambridge only after his father's death, by drowning. In 1650, Marvell became the tutor of twelve-year-old Mary Fairfax (later Duchess of Buckingham), daughter of Sir Thomas Fairfax, retired Lord General of the parliamentary forces. At the Yorkshire seat of the Fairfax family, Nun Appleton House, Marvell seems to have written, over a period of about three years, most of his non-satiric English poems. Marvell, who had been a supporter of the king, Charles I, under the commonwealth, became a supporter of Cromwell. In the summer of 1657, Marvell tutored Cromwell’s nephew and ward, William Dutton, living at Eton. Starting in 1659, Marvell was elected M.P. for his hometown of Hull, and he continued to represent it until his death, Marvell was engaged in political activities, taking p...

Noble Gases Properties

Noble Gases Properties The right column of the periodic table contains seven elements known as the inert or noble gases. Learn about the properties of the noble gas group of elements. Key Takeaways: Noble Gas Properties The noble gases are group 18 on the periodic table, which is the column of elements on the right side of the table.There are seven noble gas elements: helium, neon, argon, krypton, xenon, radon, and oganesson.Noble gases are the least reactive chemical elements. They are nearly inert because the atoms have a full valence electron shell, with little tendency to accept or donate electrons to form chemical bonds. Location and List  of the Noble Gases  on the Periodic Table The noble gases, also known as the inert gases or rare gases, are located in Group VIII or International Union of Pure and Applied Chemistry (IUPAC) group 18 of the periodic table. This is the column of elements along the far right side of the periodic table.  This group is a subset of the nonmetals.  Collectively, the elements are also called the helium group or the neon group. The noble gases are: Helium (He)Neon  (Ne)Argon (Ar)Krypton (Kr)Xenon (Xe)Radon (Rn)Oganesson (Og) With the exception of oganesson, all of these elements are gases at ordinary temperature and pressure. There havent been enough atoms produced of oganesson to know its phase for certain, but most scientists predict it will be a liquid or solid. Both radon and oganesson consist only of radioactive isotopes. Noble Gas Properties The noble gases are relatively nonreactive. In fact, they are the least reactive elements on the periodic table.  This is because they have a complete valence shell. They have little tendency to gain or lose electrons. In 1898, Hugo Erdmann coined the phrase noble gas to reflect the low reactivity of these elements, in much the same way as the noble metals are less reactive than other metals.  The noble gases have high ionization energies and negligible electronegativities. The noble gases have low boiling points and are all gases at room temperature. Summary of Common Properties Fairly nonreactiveComplete outer electron or valence shell (oxidation number 0)High ionization energiesVery low electronegativitiesLow boiling points (all monatomic  gases at room temperature)No color, odor, or flavor under ordinary conditions (but may form colored liquids and solids)NonflammableAt low pressure, they will conduct electricity and fluoresce Uses of the Noble Gases The noble gases are used to form inert atmospheres, typically for arc welding, to protect specimens, and to deter chemical reactions. The elements are used in lamps, such as neon lights and krypton headlamps, and in lasers. Helium is used in balloons, for deep-sea diving air tanks,  and to cool superconducting magnets. Misconceptions About the Noble Gases Although the noble gases have been called the rare gases, they arent particularly uncommon on Earth or in the universe. In fact, argon is the 3rd or 4th most abundant gas in the atmosphere  (1.3 percent by mass or 0.94 percent by volume), while neon, krypton, helium, and xenon are notable trace elements.​ For a long time, many people believed the noble gases to be completely nonreactive and unable to form chemical compounds. Although these elements dont form compounds readily, examples of molecules containing xenon, krypton, and radon have been found. At high pressure, even helium, neon, and argon participate in chemical reactions. Sources of the Noble Gases Neon, argon, krypton, and xenon all are found in air and are obtained by liquefying it and performing fractional distillation. The major source of helium is from the  cryogenic separation of natural gas. Radon, a radioactive noble gas, is produced from the  radioactive decay of heavier elements, including radium, thorium, and uranium. Element 118 is a man-made radioactive element, produced by striking a target with accelerated particles. In the future, extraterrestrial sources of noble gases may be found. Helium, in particular, is more abundant on larger planets than it is on Earth. Sources Greenwood, N. N.; Earnshaw, A. (1997). Chemistry of the Elements (2nd ed.). Oxford:Butterworth-Heinemann.
