For centuries upon centuries, humans have developed ideas based on their experimental findings. Due to the fluidity of science, these ideas have been through many stages before the most plausible one is decided upon. Atomic theory began with Greek philosophers in Ancient times and carried over to modern science. The knowledge acquired by past scientists has had a great impact on discoveries made by those that followed. Furthermore, the models of the atom that Ernest Rutherford and J.J. Thomson proposed have definitely enhanced my Bohr model. Thomson’s “plum pudding model” was a pivotal pre-requisite to many updated models of the atom, for it incorporated the, recently discovered, electron. This only preceded Rutherford’s more accurate model, which conveyed that these electrons had a specific location relative to the rest of the atom. In my Bohr model, it is depicted that these very subatomic particles follow a specific circular orbit and can shift its path depending on the present conditions. Though the location and presence of the electron varies between models, all versions of it have information that holds true throughout. Aside from the negatively charged region to which the electrons belonged, the other major part of the atom is positively charged. J.J. Thomson’s model recognized most of the atom as positively charged with the occasional electron to balance the charge out. As a result of Rutherford’s gold-foil experiment, his model isolated the positive charge in a region unique to that of the electrons. The positively charged region was thus coined the “nucleus” of an atom, which was featured as the central point of my atomic model. This even further proves the point that each model of the atom supplies information for their subsequent relatives. Some may say that the models of the atom only replace each other, but this is not true. Every model leading up to the next

Lab report Introduction- An ester is “any class of often fragrant organic compounds that can be represented by the formula RCOOR′ and that are usually formed by the reaction between an acid and an alcohol with elimination of water.” We set out to create these esters on our own by combining acids like acetic acid, butyric acid, and benzoic acid with certain alcohols like ethanol, methanol, or pentanol. Each had a unique smell, which we would try to determine by smelling each. Objective- To…

Connor Grover Ms. Webber Chemistry A 16 January 2015 The CNO Cycle (Carbon-Nitrogen-Oxygen Cycle) Nuclear processes take place when the nucleus of an atom is unstable. Nuclear process happen all around our lives, including medical, industry, energy, military, and space. The nuclear process that caught my eye the most was the CNO Cycle (Carbon-Nitrogen-Oxygen Cycle). This process is vital to life on Earth because it produces a majority of the energy in most stars and a small amount in the Sun.…

EXPERIMENT 9: The Grignard Reaction Written by Albert T. Sneden, VCU Department of Chemistry with revisions by L.M. Moses The carbonyl group, as well as other electrophilic functional groups, undergoes facile reactions with nucleophilic reagents. Among the most useful nucleophilic reagents are those classified as organometallic reagents since the by-product of the reaction is usually an insoluble metallic salt. One of the most common organometallic reagents is a Grignard reagent which, when…

Fractional Crystallization Suggested Reading 8.1-8.3 Introduction A solution is a homogeneous mixture of at least two components. Homogeneous means only one phase/state is visible. For example sugar water; you only see one liquid phase when looking at the glass even though both sugar and water molecules are present. Sugar water is a solution of two components, sugar which is termed the solute and water which is the solvent. The solute is the component present in a lesser amount…
