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

The First & Only-Atomic Bomb The atomic bomb‚ also known as the atom bomb or fission bomb‚ a weapon whose explosive power originates from the fission of atomic nuclei‚ a reaction in which an atomic nucleus splits in two. When the nucleus of a heavy atom‚ such as the element uranium-235‚ which is what the atom bomb is made out of‚ is split‚ a certain amount of mass disappears and an equivalent amount of energy is released. This was expressed by the equation E=mc2 (energy = mass times the speed of

Decision to Drop Atomic Bombs The Justification behind the Detonation of The Little Boy and The Fat Man How could anyone possibly justify a decision that would result in over 265‚000 potentially innocent people losing their lives? Justifications like this have been made throughout history by evil leaders with mal-intentions‚ or by psychopathic fundamentalists‚ but never by a governmental organization as respected and trusted as the United States. How is it possible that the most financially

of the Bomb‚ focuses on the impact war has on humanity. On a more complex level‚ the poem illustrates how the desensitization of war and its results drive the world into hopelessness. Amichai begins his poem using a statistical analysis of the bomb. The bomb begins as a mechanical and emotionless object that is represented as holding limited capacity for destruction. It is described as having a thirty centimeter diameter and an effective range of about seven meters. The effects of the bomb seem miniscule

Introduction Atomic Absorption Spectrometer (AAS) is an analytical equipment commonly used for the detection of heavy metals in particular sample. The first step to analysis in the AAS is the atomization of the desired element by converting it to a gaseous state. The atoms then absorb the energy emitted from the hollow cathode lamp corresponding to the desired element and a detector reads the signal and records the results. The results may be used quantitatively or qualitatively depending on the

John Dalton was an English chemist‚ physicist‚ and meteorologist. Dalton was born in 1766. He is best known for his work in color blindness‚ and of course‚ his Atomic Theory. His theory gave us an idea about what the universe is really made up of‚ and he paved the way for many more important scientific discoveries after he died in 1844. His theory was simple: He stated that all matter is made of atoms. He based his theory on two laws: the law of conservation of mass and the law of constant composition

The Population Bomb a theory developed by Paul Ehrlich in the 1960’s predicted that in less than two decades the overpopulation of the world would not be able to sustain itself leading to mass starvation and deaths. To achieve a more balanced carrying capacity he argued that population control at the family level would be necessary for society to continue to function. This type of thinking led to the implementation of population control programs‚ such as female sterilization that was forced upon
