Nuclear Physics Essay - 1170 Words

The Nucleus of an atom consists of protons, and neutrons. A proton has a charge of positive one while a neutron has no electric charge at all and both have a mass of one atomic mass unit. These two particles are known as nucleons. On the outside of the nucleus electrons can be found. These electrons have a charge of negative one and a mass that is negligible because of how small it is compared to the nucleons. The discovery of the electron showed that the atom might have an internal structure. It was originally thought to be a conglomerate or plum pudding as it was called. But it was soon discovered using the gold foil experiment. Some of the particles were scattered backwards. Because of these results, it was theorized that†¦show more content†¦So after going through alpha decay, the charge and mass of the nucleus has changed, changing the the element itself. ÃŽ ² Beta particles are the negatively charged electrons that are emitted by the nucleus of an atom. Atoms that undergo beta decay do not experience mass changes because the mass of an electron is only a small portion of the atomic mass unit. Because of this, the mass of the nucleus that experiences beta decay only changes by a miniscule amount. Beta decay occurs when neutron changes into a proton. When this happens the number of protons changes which in turn changes the atomic number. ÃŽ ³ Gamma rays are different from alpha and beta decay because they are a type of electromagnetic radiation. Gamma rays are high energy photons. They are similar to visible photons emitted by a light bulb but the wavelength is much shorter. Because of this they have a much higher energy level. The gamma rays are emitted when an atom undergoes a change in the arrangement of the protons and neutrons within the nucleus. The mass number and atomic number do not change when a nucleus emits a gamma ray. Nuclear Reactions When nuclei of atoms come close enough together they can interact and produce a powerful reaction. These reactions can either be endothermic or exothermic. There areShow MoreRelatedNuclear Physics Of The Society Development1374 Words   |  6 PagesNuclear physics in the society development Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions.

Research design and methodology This section of the research develops knowledge of the various methods or approaches which will be adopted for the completion of this research program. For the execution of the research, there is a need to gather quality data. Research design or method: quantitative research method has been chosen after analysing various available research methods. This research method has been selected with a motive to gather quality data for the achieving the objectives framed for the research. The quantitative method uses primary and secondary methods of data collection for gathering the relevant data for the research program (Patel, 2009). Research approach: quantitative research approach has been selected after evaluating different approaches available. This approach will help in gathering reliable data for the execution of the research (Acaps, 2012). Data collection: a collection of data is an important aspect of the research which forms a base for the successful completion of the research. Primary and secondary methods of data collection have been chosen for this project. The motive behind the selection of these methods is to gather data in large quantity and updated data (Mwamadzingo, 2011). Data which is available in raw form and is collected from the respondents directly is termed as primary data. Secondary data is the second-hand data which is gathered from the reliable sources (Lehman, 2011). Procedures and techniques: a technique will be adopted for the analysis of the collected data. Random sampling technique will be adopted which will ensure that data is analyzed within the limited time frame and limitations are not creating an impact on the execution process of the research (Etikan Bala, 2017). Data analysis: this research program will be based on the quality data collected on the basis of the primary and secondary data. Analysis process will be initiated with the use of random sampling technique. This technique has been selected with a motive to analyze the data effectively and forming a conclusion. The analysis is an important part as the relevancy of the data can be maintained with analysis of the data. Research strategies: strategies are adopted for conducting the research in a proper manner. A systematic approach will be applied by the researcher. A sequence has been developed on the basis of the systematic approach.
