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 the nucleus was like an electron moon orbiting a neutron and proton planet. Using this model, it is easier to understand how the different reactions occur.
Radio activity was discovered in 1896 by Henri Becquerel while he was working with compounds that contained uranium. Photographic plates that were used to keep out light because partially exposed when they were brought near any of the compounds that were part uranium. He speculated that the exposure was caused by some form of ray passing through the plates. He also found the some materials other than uranium contained these rays. These materials are said to be radio active. There are three kinds of radiation known as α alpha, β beta, and γ gamma radiation. These were discovered by Enrest Rutherford in 1899. Alpha particles are the nucleus of the He atom, beta particles are high speed electrons and gamma rays are high energy photons.

Alpha decay is the emission of an He nucleus. Because the alpha particles contai...

...o when the atoms are released they cannot help but mash into each other. This is where all of the extra energy comes from which causes the explosion.
Hydrogen Bombs
The hydrogen bomb is much more powerful than the atomic bomb. The actual trigger for the bomb is not TNT but instead an actual atomic bomb. The H-Bomb is made up of two different kinds of isotopes of hydrogen, deuterium and tritium. Smaller atomic bombs trigger the finale explosion for the Hydrogen bomb. Like the TNT, they compress the two isotopes into a very dense mass which initiates fusion, producing great amounts of energy. The actual bomb casing is made out of uranium. When the inside of the bomb detonates its causes the casing to undergo fission which causes even more energy to be released. The fusion reactions produces a fission reaction which totals up to a huge amount of energy.
According to Bathe nuclear fusion reactions are thermonuclear reactions in which energy is released when two hydrogen nuclei combine to form helium nucleus.
An atom, by definition, is the smallest part of any substance. The atom has three main components that make it up: protons, neutrons, and electrons. The protons and neutrons are within the nucleus in the center of the atom. The electrons revolve around the nucleus in many orbitals. These orbitals consist of many different shapes, including circular, spiral, and many others. Protons are positively charged and electrons are negatively charged. Protons and electrons both have charge of equal magnitude (i.e. 1.602x10-19 coulombs). Neutrons have a neutral charge, and they, along with protons, are the majority of mass in an atom. Electron mass, though, is negligible. When an atom has a neutral charge, it is stable.
Pierre and Marie hypothesised that radioactive particles cause atoms to break down, then release radiation that forms energy and subatomic particles.
In 1911, Ernest Rutherford found a very spectacular in such a small thing. Rutherford found that an atom has a microscopic charged nucleus. Empty space surrounds the nucleus. The nucleus is also surrounded by electrons. By this discovery Rutherford made the model of the atom.
The hydrogen bomb is a thermonuclear weapon, meaning that it requires extreme temperatures (upwards of 400 million degrees Celsius) to begin the nuclear fusion reactions that characterize it (Jordine, Hydrogen Bomb). In order to reach this temperature, there is a second bomb at its core, the explosion of which detonates the first, bigger bomb (Hirsch, 1990). The idea of a bomb as a catalyst was actually proposed years before work on the H-bomb ever even started by the nuclear physicists Enrico Fermi and Edwar...
If you watch the news you’ve probably heard all of the tension between us and North Korea with the nuclear arms. Well I have some knowledge to share with you. The first H bomb test and its predecessors, The components of the first H bomb and how it explodes. The science behind the H bomb is long and confusing, but I've simplified it enough to the point to make it understandable and interesting I hope.
The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.
Radioactive elements were not known of until about 1896 when a man named Henri Becquerel was experimenting with uranium to see why it was fluorescent under UV light. He believed that as the uranium sat in the sunlight, it absorbed sunlight and reemitted it on the paper, creating the film. He later found this to be incorrect when the uranium continued to create film when not exposed to sunlight. This was because the energy was not coming from the sun, but rather from inside the uranium.
In December 1938 a German chemist named Otto Hahn was experimenting in his lab. In the late1930s most scientists understood that everything in the universe is made up of little particles called atoms. (Even atoms are made up of little particles.) Hahn, already knew this so he began to experiment by placing a piece of metal called uranium by a radioactive element. He already knew that neutrons would speed out of the radioactive material and hit uranium
The atomic bomb is a powerful, explosive nuclear weapon. It is fueled by the fission of the nuclei of specific amounts of plutonium or uranium, in a chain reaction. The strength of the explosion created by one of these bombs is equal to the strength of an explosion created by thousands of tons of TNT.
Thesis Statement The hydrogen bomb is a nuclear weapon in which light atomic nuclei of hydrogen are joined together in an uncontrolled nuclear fusion reaction to release tremendous amounts of energy. The hydrogen bomb is about a thousand times as powerful as the atomic bomb, which produces a nuclear fission explosion about a million times more powerful than comparably sized bombs using conventional high explosives such as TNT.
Gamma radiation/emission – Gamma ray emission can be found when either alpha or beta decay occurs. Gamma rays are high energy electromagnetic rays. Gamma radiation is just the excess energy of the reaction being shed off, gamma rays do not effect mass numbers or atomic numbers. 6027Co 6028Ni + 0-1e + y
Nuclear fusion occurs when two atomic nuclei collide with enough energy to bind together to form one nucleus. Nuclear fusion occurs in the core of our sun, and is the source of its tremendous heat. In the sun hydrogen nuclei, single protons, fuse together and form a new nucleus. In the conversion, a small amount of mass is converted into energy. It is this energy that heats the sun.
The hydrogen bomb, a stronger version of nuclear bomb, which uses a fission bomb to ignite thermonuclear fuel, marked a new and extremely important stage in the nuclear arms race. Truman’s super bomb took over two years to complete. On November 1, 1952, the United States detonated the first hydrogen bomb on the pacific atoll of Eniwetok. The Soviet Union did not left far behind. Nine months later, on August 12, 1953 it tested an intermediate type of hydrogen bomb.
Scientists from earlier times helped influence the discoveries that lead to the development of atomic energy. In the late 1800’s, Dalton created the Atomic Theory which explains atoms, elements and compounds (Henderson 1). This was important to the study of and understanding of atoms to future scientists. The Atomic Theory was a list of scientific laws regarding atoms and their potential abilities. Roentagen, used Dalton’s findings and discovered x-rays which could pass through solid objects (Henderson 1). Although he did not discover radiation from the x-rays, he did help lay the foundations for electromagnetic waves. Shortly after Roentagen’s findings, J.J. Thompson discovered the electron which was responsible for defining the atom’s characteristics (Henderson 2). The electron helped scientists uncover why an atom responds to reactions the way it does and how it received its “personality”. Dalton’s, Roentagen’s and Thompson’s findings helped guide other scientists to discovering the uses of atomic energy and reactions. Such applications were discovered in the early 1900’s by using Einstein’s equation, which stated that if a chain reaction occurred, cheap, reliable energy could b...
