Chemistry 2500- Exercise C4 The Emission Spectrum of Atomic Hydrogen Objective The purpose of this lab was to calculate an experimental value for the Rydberg constant and then the ionization energy for the hydrogen atom. These values will be obtained by using a prism spectrograph to measure the wavelength value for a section of the visible line spectrum of atomic hydrogen. Theoretical Background When H+ combines with an electron it forms it’s excited state‚ H. This excited atom

ALBERT EINSTEIN and the ATOMIC BOMB The physicist Albert Einstein did not directly participate in the invention of the atomic bomb. But as we shall see‚ he was instrumental in facilitating its development. In 1905‚ as part of his Special Theory of Relativity‚ he made the intriguing point that a large amount of energy could be released from a small amount of matter. This was expressed by the equation E=mc2 (energy = mass times the speed of light squared). The atomic bomb would clearly illustrate

first ever atomic bomb was dropped on the Japanese city of Hiroshima. On August 9th‚ 1945‚ a second atomic bomb was dropped on the Japanese city of Nagasaki. In my opinion‚ the dropping of the atomic bombs “Little Boy” and “Fat Man” on Hiroshima and Nagasaki‚ was not justified. I believe it was not justified because of the effect it had on innocent civilians‚ the immorality of the operation and theories that the attack may have been racially motivated. First‚ the usage of the atomic bombs were

The United States decided to use atomic bombs on Hiroshima and Nagasaki in Japan. This bombing created devastation and death that the world had never seen before. The use of the atomic bombs has been a topic of intense debate for years following the bombing. Several reasons for such outcry pertaining to the use of the atomic bomb were the moral dilemmas behind the bombing‚ the mass destruction caused by the bombing‚ the horrible physical and emotional effects on the citizens of Japan‚ and strained

Conclusions The purpose of this experiment was to find the relationship between a substance’s specific heat and its atomic weight. In the lab‚ the substances with the higher atomic weights had less specific heat. From this‚ we can conclude that specific heat and atomic weight have an inverse relationship‚ meaning as one decreases the other increases. The reason for this is because if atoms are small‚ or light‚ they have the ability to pack tightly together‚ leaving almost no space between them

President Truman’s decision to drop the atomic bomb on the cities of Hiroshima and Nagasaki were the direct cause for the end of World War II in the Pacific. The United States felt it was necessary to drop the atomic bombs on these two cities or it would suffer more casualties. Not only could the lives of many soldiers have been taken‚ but possibly the lives of many innocent Americans. The United States will always try to avoid the loss of American civilians at all costs‚ even if that means taking

There were two atomic bombs that were dropped during World War II. There were few survivors after the atomic bombs were dropped. Both of the atom bombs had nicknames. They were dropped three days apart from each other. The first bomb was dropped on Hiroshima. The second was dropped on Nagasaki. The atomic bombs are what ended the war. After both bombs were dropped‚ Japan surrendered. Japan did not stand a chance against the United States now that they had created atomic bombs. The atom

Since World War II‚ America has been defined and shaped by the atomic bomb. In the documentary film Oliver Stone’s Untold History of the United States‚ the atomic bomb‚ it’s history‚ role‚ and it’s place in shaping the history of the United States is explained. But to understand the atomic bomb’s history and role in America‚ morally and policitally‚ World War II must be known‚ because it all really began with the start of World War II. Although a slow start of war‚ and with many historians disagreed

Further progress in the understanding of atoms did not occur until very famous scientist created the atomic theory. Here are some scientists who changed the way we learn about the atom‚ and the atomic nature of all life. Ernest Rutherford. Ernest Rutherford was another scientist that changed the atomic model.
