Nuclear Energy Nuclear energy is a strong force that holds together the nucleus in an atom. To release this energy in order to produce electricity, scientist use the processes called nuclear fusion and nuclear fission. Once the energy is released, it will change into radiation which is a form of energy. Before nuclear energy was generated, we use fossil fuel to produce electricity. However, fossil fuels such as coal and oil contributes detrimental air pollution.
When the nucleus of an atom splits or when two nuclei of different atoms combine, a large amount of energy is released in the form of heat and radiation. Their energy is termed as Nuclear Energy. Nuclear processes are used in order to generate heat or electricity from nuclear energy. These nuclear processes are performed using the earth elements. During these processes the nuclei of atoms either join together which is called fusion or they break apart which is called fission.
Nuclear physics is the study of the relationship between the nuclei of atoms. For nuclear physics to be applied in real life situations, radioisotopes are often used. These are isotopes that have an unstable protons to neutrons ratio that causes them to spontaneously undergo radioactive decay. They do this in order to change their amount of protons and neutrons and become a stable isotope of the same or a different element. To do this, they can either go through alpha decay or beta decay and depending on which one it does, it will either emit alpha particles or beta particles which will cause it to end up with a different element or isotope.
By the time of the Industrial Revolution, people used water energy, heat energy and nuclear power. Using nuclear power has spread to most countries in the world because scientists are looking at it as a real renewable source for energy. Nuclear power is the power that is produced by controlling the reaction of separating the element such as Uranium. However, when it was used to make weapons such as nuclear bombs some of its negative effects appeared after the Second World War. Also when the Chernobyl Reactor accident happened, the reactor was destroyed and a cloud of radiation spread to a huge area in Europe.
Chemical Properties: Reaction with air: - When plutonium is exposed to air it begins to oxidise, it forms a yellowish-brown outer coat and begins to tarnish. Soluble in: - Hydrochloric acid Insoluble in: - Nitric acid - Concentrated hydrogen sulfide The Critical Mass: - Around 300 grams which is only about a third of that of Uranium 235 Allotopic Structures: - Plutonium exhibits six forms of crystalline structures. The only form that exists at room temperature is the alpha structure. It has the highest electrical resistivity of any metallic
Introduction Nuclear energy is the energy that is found in the nucleus of an atom. Atoms are smaller particles, which can be divided into a material. In the nucleus of each atom there are two types of particles (neutrons and protons) which are always united. Nuclear energy is the energy that allows the permanent union of neutrons and protons. In this section, we discuss the pros and cons of nuclear energy.
Radiation is energy which is given off by matter in form of rays or high speed particles (james, 2014). There are many types of nuclear radiations and emissions. The most common rays or nuclear radiation are alpha, beta and gamma rays. The nuclear radiation originates from the nucleus of the atom (Anon., 2014). The substances who give off these rays of radiation are known to be radioactive, similar to alpha, beta and gamma rays.
What is geothermal energy? : Geothermal energy is thermal (heat) energy that is stored, generated and emanated from the Earth’s core to the Earth’s crust. How is it generated? : The earth core generates geothermal energy through the natural decay of radioactive materials such as Uranium and Potassium. This heat energy is mostly found within magma, which exists below the Earth’s crust.
Today, most of the energy we use comes from fossil fuels; coal, oil, and natural gas are all fossil fuels. Over millions of years, the decay of plants, dinosaurs, and other animals was formed into fossil fuels. These fuels lie buried between layers of earth and rock. The only way to get them out is to drill or mine for them, while fuels are still being created.
“Furthermore, what this supports is that a small amount can result in large release of energy and so this is true almost for all fossil fuel sources. And as opposed to renewable sources that large quantity cannot be absorbed from them since they need large areas. An example is coal which is of the earliest foundations of humans and one of the most powerful sources of energy used today. According to Rani (2014), 36,907.52 thousands megawatts hours was produced from coal only in Texas and only for the first Quarter. Other States such as Indiana and Ohio came after Texas generated 27,633.11 and 26,969.945 respectively from Coal only.
