Free Essays on The Darling

Li 2 Anton Chekhov’s short story â€Å"The Darling?illustrates the life of a woman named Olenka Semyonovna £Ã‚ ¬who because of her reliance on others, lives a empty life. She is a person who changes her attitude as she falls in love with different men. She always needs to be fond of someone and does not posses a personality of her own; therefore, she only finds happiness in reflecting the belief of her husbands. Olenka is portrayed as a conventional woman who is reliant, diligent and idealess. Olenka is a dependent woman who needs the love of others. In earlier days, she had loved many people such as her aunt, the school’s French master and even her father. Later on, she becomes attracted by her first husband Kukin, and â€Å"without him she [can] not sleep, but [sit] all night at her window, looking at the stars?(250). Thus, Olenka cannot feel comfort when there is no one for her to attach to. After Kukin past away in Moscow, she is expected to be heartbroken and sorrowful afterwards. Ironically, Olenka immediately seeks and falls in love with her next mate, Pustovalov. Once again, she becomes delighted and â€Å"[misses] him dreadfully, [lies] awake and [cries]?(252) when he is away on business trips. Olenka easily becomes lonely and desperate for male affection; she has to have someone who can take care of her. Olenka works hard to bring successes to her husband business. She assists in the daily activities in the theater, Tivoli, such as â€Å"[taking] part in the rehearsals, and [correcting] the actors?(249). She has become so occupied with Tivoli that she cannot detach herself from it. However, when she begins to engage with Pustovalov, Li 3 Tivoli has somehow vanished from her mind. She starts to focus all of her attentions into Pustovalov’s lumber industry. While he is away, she takes his place and works in the office to make necessary arrangements. Olenka puts so much passion into her work that s...

Lewis Structures or Electron Dot Structures

Lewis Structures or Electron Dot Structures Lewis structures, also known as electron dot structures, are named after Gilbert N. Lewis, who described them in his 1916 article titled The Atom and the Molecule. Lewis structures depict the bonds between atoms of a molecule as well as any unbonded electron pairs. You can draw a Lewis dot structure for any covalent molecule or coordination compound. Lewis Structure Basics A Lewis structure is a type of shorthand notation. Atoms are written using their element symbols. Lines are drawn between atoms to indicate chemical bonds. Single lines are single bonds, double lines are double bonds, and triple lines are triple bonds. (Sometimes pairs of dots are used instead of lines, but this is uncommon.) Dots are drawn next to atoms to show unbonded electrons. A pair of dots is a pair of excess electrons. Steps to Drawing a Lewis Structure Pick a central atom. Start your structure by picking a central atom and writing its element symbol. This will be the atom with the lowest electronegativity. Sometimes its difficult to know which atom is the least electronegative, but you can use the periodic table trends to help you out. Electronegativity typically increases as you move from left to right across the periodic table and decreases as you move down the table, from top to bottom. You can consult a table of electronegativities, but be aware different tables may give you slightly different values, since electronegativity is calculated. Once you have selected the central atom, write it down and connect the other atoms to it with a single bond. You may change these bonds to double or triple bonds as you progress.Count electrons. Lewis electron dot structures show the valence electrons for each atom. You dont need to worry about the total number of electrons, only those in the outer shells. The octet rule states that atoms wit h eight electrons in their outer shell are stable. This rule applies well up to period 4, when it takes 18 electrons to fill the outer orbitals. Filling the outer orbitals of electrons from period 6 requires 32 electrons. However, most of the time you are asked to draw a Lewis structure, you can stick with the octet rule. Place electrons around atoms. Once you have determined how many electrons to draw around each atom, start placing them on the structure. Start by placing one pair of dots for each pair of valence electrons. Once the lone pairs are placed, you may find that some atoms, particularly the central atom, dont have a complete octet of electrons. This indicates there are double or possibly triple bonds. Remember, it takes a pair of electrons to form a bond. Once the electrons have been placed, put brackets around the entire structure. If there is a charge on the molecule, write it as a superscript on the upper right, outside of the bracket.
