How Atoms Have To Look At The Structure Of An Atom
In the early years of thinking, Creek philosophers thought atoms were the building blocks of matter. Everything was built by atoms: people, trees, water and air. Atoms were viewed as eternal and indivisible. This idea was changed by Henri Becquerel, a French physicist, discovered some photographic plates had been exposed by particles coming from a piece of uranium. After this discovery, the Curies discovered that certain elements radiate particles. These particles would change into other elements. A new phenomenon was discovered-radioactivity. To understand how atoms change, we have to look at the structure of an atom; namely, the nucleus of the atom. The atomic nucleus cannot be seen by the naked eye. It is …show more content…
It had the potential to be used for explosions and power production. This was nuclear fission, or in simpler terms, the splitting of the atom. Nuclear fission is a balancing act between the attraction of strong forces and the pushing away of electrical forces inside the nucleus. Nuclear fusion involves joining two small nuclei together to produce a larger nucleus. Therefore, nuclear fusion and nuclear fission produce vastly more energy than any chemical or nuclear reaction. This technology and knowledge of atoms would usher in the bombs that fell on Hiroshima and Nagasaki in Japan to end World War II; namely the “nuclear …show more content…
When a neutron is absorbed by a U-238 there are no fission results. The nucleus that was created, U-239, emits a beta particle and then becomes an isotope of neptunium. This isotope (Np-239) emits a beta particle and later becomes plutonium. This isotope (Pu-239) undergoes fission when it captures a neutron. The half-life of neptunium-239 compared to plutonium-239 is relatively small (2.4 days to 24,000 years). Plutonium, like lead and arsenic, is a poison; it attacks the nervous system and can cause paralysis. Plutonium, either airborne or liquid, is radioactively toxic. Plutonium is even more toxic than uranium, but less so than radium. The greatest danger plutonium presents us is its capability for nuclear fission bombs. However, its best use is in breeder
How Did The Us Make Decisions About The Atomic Bomb Dbq
732 Words | 3 PagesAs many countries joined WWII, many of them were finding new ways to protect themselves. Thus the atomic bomb was born. The Germans found a way to split a uranium atom that created a huge explosion thanks to famous scientist, Albert Einstein. It wasn't long before the U.S. heard of this and started doing the same thing. In 1941, America hired a German physicist ad created a secret project called The Manhattan Project.
How Bomb Works Research Paper
1139 Words | 5 PagesThese free neutrons were introduced by creating a neutron generator. The generator is a small pellet consisting of beryllium and polonium separated by foil within the fissionable fuel core. Neutron Generator- 1. The foil is broken once the subcritical masses come together and polonium spontaneously emits alpha particles (ionizing radiation ejected by the nuclei of some unstable atoms) 2. These alpha particles clash then interact with the beryllium-9 producing beryllium-8 and free neutrons are released.
Little Boy Bombing Effects
1241 Words | 5 PagesFission (splitting) of the nucleus releases an extreme amount of energy. Even in tiny amounts fission explosions can level the area around it. “The fission of slightly more than one kilogram of plutonium 239 is thought to have released destructive energy equivalent to about 21,000 tons of TNT. (Searles, Robert)” The bomb “Fat Man” contained a bit over 1 kg (approximately two pounds) of plutonium. This bomb was dropped on August 9, 1945, three days after the initial drop of “Little Boy”.
Atomic Bomb Morality
998 Words | 4 PagesIn more recent times, the presence and capabilities of creating atomic weapons is a constant problems. Between the nuclear capabilities of the Middle East and the testing of atomic weapons in North Korea, there is a constant threat. With that threat, some of the greatest arguments of a lifetime have been brought to light. There are definite positive and negative aspects of the atomic bomb. It could save thousands of lives, while only hitting high priority targets.
Persuasive Essay: The Creation Of The Atomic Bomb
860 Words | 4 PagesIt changed the planet’s mindset, and the possibilities of science by coming up with the ideas of the bomb, experimenting and discovering ways to do it, and completing the task. It all started with the discovery of a new type of nuclear bomb, which if created correctly, could react and behave the way a bomb was supposed
Fission Vs Nuclear Fusion Essay
1284 Words | 6 PagesIn this diagram, a neutron is absorbed by a uranium-235 nucleus, as a result, it turns of a small period of time to an excited uranium-236 nucleus, with the excitation energy provided by the kinetic energy of the neutron plus the forces that bind to the neutron. The uranium-236 then splits into two, smaller, lighter, fast-moving elements (these are known as fission products) and releases three free neutrons as well as gamma rays. Fusion and fission are nuclear reactions. Fusion is the binding of two atoms to produce a heavier atom while fission is splitting of an atom. Fusion releases more energy than fission and powers the stars.
Summary: The Utilization Of The Atomic Bomb
1739 Words | 7 PagesNo other technological innovation has disrupted the natural world more than the atomic bomb. The atomic bomb is the greatest explosion of energy to ever have been created by man. The explosion of an atomic bomb is created through multiple nuclear chain reactions with either uranium or plutonium. The two instances in which the atomic bomb has ever been used in an act of violence was during the attacks on Japan during World War II. The war in the Pacific theater was from December 1941 through August 1945, between Japanese soldiers and American forces.
Persuasive Essay On Nuclear Energy
3678 Words | 15 PagesNuclear energy is one of the several alternative energy sources that have been introduced ever since. Nuclear energy’s various advantages entice many countries to start practicing it. One must consider the amount of energy generated by nuclear fuels, as they are highly-concentrated energy sources. Small uranium pellets, which are the most common form of fuel in generating nuclear energy, can generate as much electricity as a trainload full of coal does. In addition, nuclear power plants do not produce green house gases as byproducts.
Nuclear Power Argumentative Essay
944 Words | 4 PagesNuclear energy is something that we`ve all heard about. It carries risk and potential. When an atom (Uranium and Plutonium in nuclear power plants) is bombarded by neutrons, it can be split, causing fission. This fission releases more neutrons, which causes a chain reaction. Nuclear power plants use this use the heat that is created by fission to heat water that spins their turbines (“Nuclear Energy”).
Nuclear Waste Spill Affect The Environment
199 Words | 1 PagesEscherichia Coli aka E. Coli, has the ability to absorb and contain uranium. Although there are strains of it that can cause disease, this can handle nuclear waste. While it would be good if this bacteria did disappear, nuclear waste spills could get out of hand. For example, if a spill had gone into the ocean, this could potentially get into our water supply and harm marine animals. By harming the marine animals, they could eventually mutate or become harmful to us when consumed.

Humans ' interest in nuclear power leads to engaging this power in a lot of fields. It was used to provide heat because splitting reaction produces heat naturally. In addition, nuclear power can help us produce electricity, which is required in different fields all around the world. Moreover, It is used to diagnose diseases in the hospitals by using its radioactivity.
Nuclear Fission Research Paper
1000 Words | 4 PagesIn order to do this a process called nuclear fission needs to happen. This is where the nucleus of an atom is split in order to release energy. Nuclear fission begins with the nucleus splitting into several small fragments, known as “nuclear products” (“Nuclear Energy”, www.nationalgeographic.com). Nuclear products are half of the original mass of the nucleus. These nuclear products, or fission products, cause other atoms to split.
Nuclear Energy
1433 Words | 6 PagesIntroduction 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.
Nuclear Energy Good Or Bad
1917 Words | 8 PagesThis in turn, is a way to combat global warming. Nuclear energy works on the principle of splitting the nucleus of an atom to smaller nuclei, similar to the idea of splitting a watermelon into smaller pieces. This fission results in the release of large amounts of energy, which is used to turn electric generators to give an equally vast amount of electricity. Uranium is most commonly used for such fission since it is one of the sparingly few fissile isotopes present in the periodic table. Some would say the mining of Uranium for use in nuclear fission is as damaging to the environment as coal, or even more due to the radioactive nature of the materials being mined(Aref, n.d.).
