What elements was used in the atomic bombs?

The atomic bombs dropped on Hiroshima and Nagasaki in World War II used uranium-235 and plutonium-239 as their primary elements. The bomb dropped on Hiroshima (Little Boy) used uranium-235, while the bomb dropped on Nagasaki (Fat Man) used plutonium-239.


Is the bomb little boy a fission or fusion reaction?

The "Little Boy" bomb used in the Hiroshima bombing was a fission bomb, specifically a gun-type uranium-235 bomb. It relied on the nuclear fission of uranium-235 to release a massive amount of energy.


How much uranium was in little boy?

About 64 kilograms- but only about 600 milligrams was converted to energy. See the link below for a good article on Little Boy.


What is nickname for the bomb in hiroshima?

the bomb was nicknamed "Little Boy", and it used the element of uranium-235.


How much plutonium was USED in little boy?

The Little Boy atomic bomb used about 64 kilograms (141 pounds) of highly-enriched uranium-235, not plutonium. Plutonium was used in the Fat Man bomb, which used about 6.2 kilograms (13.6 pounds) of plutonium.


Why was plutonium used in Fat Man?

There are two materials that can be used to make an atomic bomb: Plutonium-239 and uranium-235. Of the two plutonium-239 is easier to acquire. By the end of the Manhattan Project the U.S. only had enough uranium-235 to make one bomb, and that was Little Boy.


What element was used as fuel for the little boy bomb?

The Little Boy bomb, dropped on Hiroshima in 1945, used enriched uranium-235 as its fuel. This type of bomb is known as a uranium-based atomic bomb, and it functions through the process of nuclear fission.


What type of material was the first nuclear bomb made of?

The first nuclear bomb, known as "Little Boy," used uranium-235 as its fissile material. It was an enriched uranium bomb that was detonated over Hiroshima, Japan, in 1945.


What were the atomic bombs made of?

little boy the first atom bomb used uranium 235 and fat man the second one used plutonium 239 surrounded by high explosives little boy used uranium 235 and fat man used plutonium 239<------- That answer makes no sense, and ima girl and i asked that question. What are you stupid? Little Boy was the first bomb, and Fat Man was the second.


What radioactive isotope did the first atomic bomb contain?

The first atomic bomb, "Little Boy," contained uranium-235 as its radioactive isotope.


Element used in first atomic bomb?

The first bomb exploded, the Trinity test bomb, used plutonium. The first bomb deployed, dropped on Hiroshima, used uranium 235. The second bomb deployed, dropped on Nagasaki, used plutonium 239.


How did they made the bomb in 1945?

The nuclear weapons were developed in the Manhattan Project. The development took years of research and work to learn how to produce Uranium 235 and Plutonium, and how to fabricate them into a bomb. The Uranium bomb, known as Little Boy, used a gun system to fire a plug of uranium into a larger target of uranium. The Plutonium bomb, known as Fat Man, was a round ball of plutonium that was crushed by explosive charges. The link below will take you to an article on the Manhattan Project.
