ScienceStruck Staff Harvesting the energy residing in an atom was an unimaginable idea until the midth century.
It was Sir Ernest Rutherford, considered the 'father of nuclear physics', who first became aware of the energy trapped in an atom. While examining the result of an experiment conducted by John Cockcroft and Ernest Walton, the latter being his doctoral student, he realized the massive amount of energy produced in the 'splitting' of an atom.
However, he also noted that looking for a stable source of energy in this process was pointless, since the energy required to split an atom of a light element was so much that the surplus output came up to a paltry amount.
While this notion holds true for lighter elements even to this day, the scientific world was yet to realize the capability of heavy, radioactive elements to produce a highly energy-efficient fission chain reaction.
To understand nuclear power, we must first have a basic understanding of the structure of the atom and the phenomenon of radioactivity. Those who are already familiar with what I'm about to explain may skip the theoretical illustrations.
The Atom The atom consists of two regions: The nucleus is made up of protons, which are positively charged, and neutrons, which do not have any electric charge. Protons and neutrons are called 'nucleons', since they make up the nucleus of the atom.
Electrons are negatively charged particles and orbit the nucleus at a distance directly variable with their energy level the further an electron is from the nucleus, the more energy it holds and vice versa. The characteristic physical and chemical properties of an element are imparted due to the number of protons present in the nucleus, which is known as the atomic number of the element.
In other words, the number of protons in an atom's nucleus gives the element its 'identity'. While an atom can lose or gain electrons while maintaining its atomic number i. This changes or transmutes the atom of a particular element into an atom of a different one. The loss of protons, neutrons, or splitting of a large atom into smaller ones is due to radioactivity.
Radioactivity is observed in elements having an atomic number higher than Bismuth, the 83rd element, is very slightly radioactive, but its half-life period is so long a billion times more than the age of the universe that it is considered stable.
The cause behind radioactivity lies in the force which holds together identically charged protons in a nucleus. As any eighth grader would know, like charges repel each other, which should result in positively charged protons repelling each other when bound together in the nucleus.
The reason that does not happen is a short-range force known as 'nuclear force'. Within a specified range, nuclear force is one of the strongest forces in the universe and requires a massive amount of energy to overcome.
However, after a limit considered to be 2. Heavy nuclei, such as those of uranium and radium, have protons close to or outside the outer limit of the pull of nuclear force, rendering the atom unstable.Nuclear power is widely perceived as an unreliable technology.
However, it is a significant source of power. Know about the pros and cons of nuclear power in this write-up. Advantages and disadvantages of nuclear power In this section we analyze the advantages and disadvantages of nuclear power.
Nevertheless, most organizations related to nuclear energy are already positioned for or against the use of nuclear power.4/4(1K). Nuclear power, or nuclear energy, is the use of exothermic nuclear processes carried out in controlled manner, to generate useful heat and electricity.
Nuclear power works by using the energy from nuclear fission or fusion to generate heat. The nuclear reactors can be manufactured small enough to power the ships and submarines, The nuclear power stations do not burn the fossil fuels to produce the electricity, So, They do not produce damaging, The nuclear energy can be produced from the nuclear power plants even in the cases of rough weather conditions.
