As Chemistry Summary of how the atoms have changed throughout the years? One of the first founders of the idea of atoms was called Democritus‚ which was in 430 BC. He argued that there were an infinite number of different types of atoms. They were all different shape however they were made from the same stuff. He describes atoms as indivisible particles and also explained certain natural occurrences such as the existence of elements. Atomos (in ancient Greek) means “that which cannot be further

and hardheadedness. In scene 2 when Ismene tries to take partial blame for the burial of Polyneices‚ Antigone refuses her. This shows Antigone’s pride for her actions and her protectiveness and loyalty to her family. Ismene is included to act as a foil to Antigone’s character. Where Ismene not included in the play‚ the play would not have such a great effect. Ismene represents the average women in this Greek society. Had her character not been introduced the reader would assume that all women

and since the atoms had a neutral charge‚ they must also include protons. This led him and other to think of the atom as a positively charged cloud with electrons randomly scattered in it. Rutherford later found this model to be false from his metal foil experiments because the large deflections of the alpha particles could only occur with a large‚ concentrated mass at the center of the atom. This supported the idea that there was a nucleus‚ a dense center of protons and neutron. b) Nuclear Models

does and how he behaves. Furthermore he is a minor character because the whole story deals with Mr. Kelada. In my point of view Mr. Kelada is the protagonist and the narrator is the foil‚ the so called contrast figure. He only reflects the good and the bad features of the protagonist. In this particular story the foil reflects more the negative than the positive traits. The narrator himself is an English snob. He is not very fond of staying with somebody else in a cabin for fourteen days. Furthermore

File: GeomB 2011 Answers 8.10.11 No Calculators: Updated: August 10‚ 2011 A concave polygon looks sort of like a vertex has been ’pushed in’ towards the inside of the polygon. A convex polygon has all the vertices of the polygon pointing outwards‚ away from the interior of the shape. Think of it as a ’bulging’ polygon. A regular polygon is a polygon which is equiangular (all angles are congruent) and equilateral (all sides have the same length). Regular polygons may be convex or star. (5

begins to rapidly decline after Ophelia’s death and seeks to release him emotion and anger by killing Claudius. While Hamlet continues to plan the murder of the King‚ the King and Laertes also strategize the death of Hamlet. Laertes becomes another foil for Hamlet as he seeks to avenge the accidental death of Polonius. His irrational behavior and anger for Hamlet accidentally killing Polonius make the audience more inclined towards the cause of Hamlet‚ not Laertes and Claudius. Laertes is used as

Also Thomson’s theory couldn’t explain the atomic spectrum and other properties of the atom. The Gold Foil experiment led to the discovery of the Nuclear Model and the existence of an atomic nucleus and protons. In the experiment‚ Rutherford directed a narrow beam of alpha particles at a thin piece if gold foil. With the prediction that the positive charges would go through the foil‚ Rutherford has found that every one and a while‚ a positive particle that was deflected bounced back because
