AnswersDriveWhen a uranium-235 atom absorbs a neutron and fissions into two new atoms, it releases three new neutrons and some binding energy. Two neutrons do not continue the reaction because they are lost or absorbed by a uranium-238 atom. This causes a nuclear chain reaction. For more on this topic, see Nuclear Fission.
Also know, how does an atomic bomb work?
There are two types of nuclear bombs, fission bombs and fusion bombs. Fission means to break apart and fusion to merge. The fission bomb works on the principle that it takes energy to put together a nucleus with many protons and neutrons. Splitting the nucleus up again then releases some of that energy.

What would happen if you split an atom?
Transcript of What would happen if you split an atom. when you split an atom there is a huge explosion. when an atom splits in half some of the matter in the atom is converted into energy. The broken pieses become atoms for another element.

Why did they call the atomic bomb Little Boy?
"Little Boy" was the codename for the atomic bomb dropped on the Japanese city of Hiroshima on 6 August 1945 during World War II by the Boeing B-29 Superfortress Enola Gay, piloted by Colonel Paul W. Tibbets, Jr., commander of the 509th Composite Group of the United States Army Air Forces.

Who built the first atomic bomb?
Cynthia C. Kelly, Oppenheimer and The Manhattan Project: Insights Into J Robert Oppenheimer, "Father Of The Atomic Bomb" Cynthia C. Kelly, The Manhattan Project: The Birth of the Atomic Bomb in the Words of Its Creators, Eyewitnesses, and Historians.

Why was the atomic bomb dropped?
President Harry S. Truman, warned by some of his advisers that any attempt to invade Japan would result in horrific American casualties, ordered that the new weapon be used to bring the war to a speedy end. On August 6, 1945, the American bomber Enola Gay dropped a five-ton bomb over the Japanese city of Hiroshima.

What is used in an atomic bomb?
A general name given to any weapon in which the explosion results from the energy released by a reaction involving atomic nuclei, either by fission—of uranium or plutonium; or, fusion—of a heavier nucleus with two lighter hydrogen ones. Thus, the A-for atomic bomb, and the H, for hydrogen bomb are both nuclear weapons.

Can an atom be divided further?
Yeah it's true we keep on listening atom is the building block of matter but surely it can be divided into electrons , neutrons , protons etc. And further these can also be divided to quarks. they are divided into electron,proton & neutron… these are further divided to the smallest particles known as quarks…

How did they make an atomic bomb?
Atomic bombs are made up of a fissile element, such as uranium, that is enriched in the isotope that can sustain a fission nuclear chain reaction. When a free neutron hits the nucleus of a fissile atom like uranium-235 (235U), the uranium splits into two smaller atoms called fission fragments, plus more neutrons.

What happens when you split a uranium atom?
If enough of these expelled neutrons cause the nuclei of other U-235 atoms to split, releasing further neutrons, a fission 'chain reaction' can be achieved. When this happens over and over again, many millions of times, a very large amount of heat is produced from a relatively small amount of uranium.

Can you split the atom?
Researchers have just shown how a single atom can be split into its two halves, pulled apart and put back together again. While the word "atom" literally means "indivisible," the laws of quantum mechanics allow dividing atoms -- similarly to light rays -- and reuniting them.
11
How is it possible to split an atom?
In a nuclear reaction, scientists shoot a whole bunch of neutrons at uranium-235 atoms. When one neutron hits the nucleus, the uranium becomes U-236. When it becomes 236, the uranium atom wants to split apart. After it splits, it gives off three neutrons and a lot of energy.
12
Why is so much energy released when an atom is split?
The splitting of a uranium atom releases energy. This process is called “nuclear fission”, since the centre of an atom is called its nucleus. When a uranium atom splits it gives off more neutrons, which can then split more atoms, and so the energy level rapidly multiplies.
13
How heavy is a nuclear bomb?
A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can release energy equal to more than 1.2 million tons of TNT (5.0 PJ). A nuclear device no larger than traditional bombs can devastate an entire city by blast, fire, and radiation.
14
Who first achieved nuclear fission?
Nuclear fission of heavy elements was discovered on December 17, 1938 by German Otto Hahn and his assistant Fritz Strassmann, and explained theoretically in January 1939 by Lise Meitner and her nephew Otto Robert Frisch.
15
How do you split an atom in half?
This laser beam is key to splitting the atom. So, if the atom is moved to the right and left at the same time, it will split. "The atom has kind of a split personality, half of it is to the right, and half to the left, and yet, it is still whole," explained Andreas Steffen, the publication's lead author.
16
What is the hydrogen bomb?
hydrogen bomb or H-bomb, weapon deriving a large portion of its energy from the nuclear fusion of hydrogen isotopes. In an atomic bomb, uranium or plutonium is split into lighter elements that together weigh less than the original atoms, the remainder of the mass appearing as energy.
17
What is created from fission?
Nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. In the fission process, a large quantity of energy is released, radioactive products are formed, and several neutrons are emitted.
18
Where does uranium 235 come from?
Uranium-235 (235U) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a fission chain reaction. It is the only fissile isotope with a primordial nuclide found in significant quantity in nature.

What is the process of nuclear fusion?
Nuclear fusion is the process in which two atomic nuclei are fused together into a larger single nucleus, releasing energy in the process. In proton-proton fusion, four hydrogen atoms are fused into a single helium-4 atom, releasing a lot of energy in the process.
