Nuclear Fusion Learning the process of nuclear fusion is one of scientist’s greatest discoveries. From how much energy is radiated from the sun to the creation of the hydrogen bomb, nuclear fusion has impacted our world much more than we think. Within this paper, the history and description, importance, relation to our chemistry class, and current research regarding the topic will be explored. In the 1930’s, nuclear fusion was only a process known by scientists that explained how the sun and other stars yielded an enormous amount of energy. But during the 1950’s, scientist discovered a way to explore how and where the energy derives. They found that when two light atoms, often isotopes of hydrogen, collide together at extremely high speeds, they create a larger atom, but also release a large amount of energy in the process. Heavier atoms are much less likely to fuse, and any atom heavier then iron will not fuse at all. After fusion, the mass of the product atom will be less than the sum of the two reactants’ mass. This mass is often calculated by one of Einstein’s most popular formulas, E=mc2 (m representing mass, c representing the speed of light). Overall, this equation states that even when the amount of mass that “disappears” is very small, the amount of energy produced is still very large. Nuclear fusion naturally occurs often on Earth, such as four hydrogen nuclei fusing together to create a helium atom. But, scientists discovered a process that greatly increases the energy output of nuclear fusion called a thermonuclear reaction. This type of reaction created what we call the hydrogen bomb. As heat increases in the casing, gas particles move faster and therefore cause more collision. When the temperature reaches approximately 100,000,000oC, the hydrogen atoms collide so powerfully that they create a mass explosion. In general, scientists found a way to harness a reaction at temperatures completely unknown to earth and create a bomb from it.
Many people are dreaming of a way to use nuclear fusions power under more
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter. The first fission bomb test released the same amount of energy as approximately 20,000 tons of TNT. The first thermonuclear bomb test released the same amount of energy as approximately 10,000,000 tons of TNT.

In Favor of Nuclear Power
Nuclear power, or nuclear energy, is the use of exothermic nuclear processes, to generate useful heat and electricity. The term includes nuclear fission, nuclear decay and nuclear fusion. Presently the nuclear fission of elements in the actinide series of the periodic table produce the vast majority of nuclear energy in the direct service of humankind, with nuclear decay processes, primarily in the form of geothermal energy, and radioisotope thermoelectric generators…

this, you can discover information such as the gravitational force and mass of a black hole.
Black holes are born when an object contains enough gravitational force to overpower the nuclear fusions within. These fusions typically occur within stars up to 10x greater than our own. Inside a star, the nuclear fusion takes place within its core, fusing two hydrogen atoms to create helium atoms in order to release energy. This process takes up most of the star’s life, however, once a critical amount…

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. My views on this nuclear process is that the advantages are much…

2. Explain the conditions necessary for an H to He fusion reaction to occur and what happens.
If we start with the most basic assumptions, we will Hydrogen in abundance if we wish the reaction to yield any appreciable energy. To get atoms to fuse, they need to overcome the most basic of fundamental forces –the Strong Nuclear Force (sometimes called the Coulomb Barrier). The electrostatic repulsion between the protons of each element…

He lived in a log cabin that his grandpa, a Mormon settler ,built . He was a talented scientist from a young age, and began inventing in grade school. In 1938, he made a prototype of the first electric television, and went on to do research in nuclear fusion. Despite his consistent success, Farnsworth was swarmed with lawsuits and died, in debt, in Salt Lake City on March 11, 1971
