An Atomic bomb is used for main just destorying other things. This weapon is classified as a nuclear weapon.This essay is going to tell you about how an atom bomb works.

An atom bomb works by initiating a nuclear chain reaction, which releases a huge amount of energy relative to conventional explosives.Like when The United States bombed Japan in 1945. When Japan was bombed this caused a massive explosion. This happened becaWhen this reaction occurs, the split atom will also give off two or three of its "spare" neutrons, which are not needed to make either of the parts after splitting. These spare neutrons fly out with sufficient force to split other atoms they come in contact with. In theory, it is necessary to split only one U-235 atom, and the neutrons from this will split other atoms, which will split more...so on and so forth. All of this will happen within a millionth of a second.use nuclear reactions occur when neutrons are fired at closely packed atoms with heavy nuclei.

This process is known as fission. A fission is when heavy nuclei break apart into lighter nuclei when hit by a neutron, in turn generating more neutrons which bombard other nuclei, creating a chain reaction. By breaking down the nuclei themselves rather than releasing energy through a conventional chemical reaction, atom bombs can release more than 80 terajoules of energy per kilogram (TJ/kg).

The element used in atomic bombs is Uranium-235. Uranium's atoms are unusually large, and henceforth, it is hard for them to hold together firmly. This makes Uranium-235 an exceptional candidate for nuclear fission. Uranium is a heavy metal and has many more neutrons than protons. This does not enhance their capacity to split, but it does have an important bearing on their capactiy to facilitate an explosion. When a U-235 atom splits, it gives off energy in the form of heat and Gamma radiation, which is the most powerful form of radioactivity. Uranium is not the only material used for making atomic bombs. Another material is the element Plutonium, in its isotope Pu-239. However, Plutonium will not start a fast chain reaction by itself.
