Free Essays on Dimmesdale

Dimmesdale: Someone from Above or Below? Some people believe that a novel’s central character can be identified within the first few chapters of a novel. This could be no further from the truth when it comes to the Scarlet Letter. The Scarlet Letter’s main character is noticed in the first chapters as Arthur Dimmesdale, the man who is responsible for the scarlet letter ever happening. Dimmesdale denies his guilt about the scarlet letter and ends up in an emotional rollercoaster that puts the main focus on him and his well being. If one looks at where he goes in this â€Å"rollercoaster† I find myself seeing his links to the other characters both physically and emotionally. The bad and the good things in his emotional rants show his struggle to find purity in his life and his want to be rid of his guilty conscious. Although there are several characters that also face difficult struggles in their lives, only Dimmesdale was able to bring out the true essence that became the Scarlet Letter. Arthur Dimmesdale is a truly essential character to the Scarlet Letter, in that without him the scarlet letter wouldn’t have been, and the novel never would have been written. He becomes the main focus in the beginning when Hester was on trial. Although Dimmesdale could have taken the easy way out and accepted that he did commit a sin and move on with his life, he decides that he will keep it internally and pretend it never happened. This denial sets his character up for an emotional rollercoaster that will eventually come with his guilty conscious. This â€Å"rollercoaster† that Dimmesdale faces becomes his battle with fantasy and reality. His fantasy being the unobtainable pureness that he was always searching for, it became the only way he thought he needed to cleanse his soul. The reality was the scaffold, and his ties to it because of his guilt. Dimmesdale’s battle with the fantasy and reality is evident when he is walking through the fo...

Atomic Number 5 Element Facts

Atomic Number 5 Element Facts Boron is the element that is atomic number 5 on the periodic table. It is a metalloid or semimetal that is a lustrous black solid at room temperature and pressure. Here are some interesting facts about boron. Fast Facts: Atomic Number 5 Atomic Number: 5Element Name: BoronElement Symbol: BAtomic Weight: 10.81Category: MetalloidGroup: Group 13 (Boron Group)Period: Period 2 Atomic Number 5 Element Facts Boron compounds form the basis for the classic slime recipe, which polymerizes the compound borax.The element name boron comes from the Arabic word buraq, which means white. The word was used to describe borax, one of the boron compounds known to ancient man.A boron atom has 5 protons and 5 electrons. Its average atomic mass is 10.81. Natural boron consists of a mix of two stable isotopes: boron-10 and boron-11. Eleven isotopes, with masses 7 to 17 are known.Boron exhibits properties of either metals or nonmetals, depending on the conditions.Element number 5 is present in the cell walls of all plants, so plants, as well as any animal that eats plants, contain boron. Elemental boron is non-toxic to mammals.Over a hundred minerals contain boron and it is found in several compounds, including boric acid, borax, borates, kernite, and ulexite. Yet, pure boron is extremely difficult to produce and the element abundance is only  0.001% of the Earths crust. Element atomic number 5 is rare in the solar system. In 1808, boron was partially purified by Sir Humphry Davy and also by  Joseph L. Gay-Lussac and L. J. Thà ©nard. They achieved purity of about 60%. In 1909  Ezekiel Weintraub isolated nearly pure element number 5.Boron has the highest melting point and boiling point of the metalloids.Crystalline boron is the second hardest element, following carbon. Boron is tough and heat resistant.While many elements are produced via nuclear fusion inside stars, boron is not among them. Boron appears to have been formed by nuclear fusion from cosmic ray collisions, before the solar system was formed.The amorphous phase of boron is reactive, while crystalline boron is not reactive.There is a boron-based antibiotic. It is a derivative of streptomycin and is called boromycin.Boron is used in super hard materials, magnets, nuclear reactor shielding, semiconductors, to make borosilicate glassware, in ceramics, insecticides, disinfectants, cleaners, cosmetics, and many other products. Boron is added to steel and other alloys. Because it is an excellent neutron absorber, it is used in nuclear reactor control rods. Element atomic number 5 burns with a green flame. It can be used to produce green fire and is added as a common colorant in fireworks.Boron can transmit part of infrared light.Boron forms stable covalent bonds rather than ionic bonds.At room temperature, boron is a poor electrical conductor. Its conductivity improves as it is heated.Although boron nitride is not quite as hard as diamond, it is preferred for use in high temperature equipment because it has superior thermal and chemical resistance. Boron nitride also forms nanotubes, similar to those formed by carbon. However, unlike carbon nanotubes, boron nitride tubes are electrical insulators.Boron has been identified on the surface of the Moon and Mars. The detection of both water and boron on Mars supports the possibility Mars may have been inhabitable, at least in the Gale Crater, at some point in the distant past.The average cost of pure crystalline boron was about $5 per gram in 2008.
