In the test bomb, the material was plutonium. Plutonium was also used in one of the bombs dropped on Japan, Fat Man. Little Boy, the bomb dropped on Nagasaki, was made of uranium.
Plutonium was and still is used for atomic bombs. The atomic bombs you are talking about would be fat man and little boy. They were the two used to bomb Hiroshima and Nagasaki Many people were killed when the b-29 bomber dropped fat man.
The only nuclear weapons ever used in war were the US's MK-1 Uranium gun bomb and MK-3 Plutonium implosion bomb.

The first atomic bomb (The Gadget) was not used on any city. It was detonated on the top of a 100 foot tall steel tower, at the Trinity Site in the Jornada del Muerto desert about 35 miles southeast of Socorro, New Mexico, on what was then the USAAF Alamogordo Bombing and Gunnery Range (now part of White Sands Missile Range) on July 16, 1945.The second atomic bomb (Little Boy) was the first to be used on a city. It was dropped by a B-29 above Hiroshima Japan on August 6, 1945.The third atomic bomb (Fatman, a deliverable version of The Gadget) was the second to be used on a city (and the first plutonium atomic bomb used on a city). It was dropped by a B-29 above Nagasaki Japan on August 9, 1945.The fourth atomic bomb (unnamed, identical to Fatman) had been manufactured by Los Alamos shortly after Fatman was used on Nagasaki and shipped to San Francisco, where a B-29 was waiting to fly it to Tinnian for use in a third attack on Japan sometime in late August. However as the Japanese indicated that they would surrender before this bomb arrived in San Francisco, president Truman issued an order that it be returned to Los Alamos instead of being loaded on the B-29 for Tinnian.All together the US had plans, facilities, and aircraft to manufacture and deliver a total of 23 atomic bombs on Japanese cities before the end of 1945:August - 3 atomic bombs (2 actually used); one MK-I uranium gun bomb (yield ~15 kilotons), two MK-III plutonium implosion bombs (yield ~22 kilotons)September - 3 atomic bombs; three MK-III plutonium implosion bombs (yield ~22 kilotons)October - 3 atomic bombs; three MK-III plutonium implosion bombs (yield ~22 kilotons)November - 7 atomic bombs; seven plutonium/uranium composite implosion bombs (estimated yield 30 to 40 kilotons)December - 7 atomic bombs; seven plutonium/uranium composite implosion bombs (estimated yield 30 to 40 kilotons)
they used uranium and plutonium.
Both Uranium & Plutonium were used.
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.
Plutonium was used in the Trinity test, Uranium in the first combat weapon.
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.
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.
The first atomic bomb used in warfare was the "Little Boy" bomb dropped on Hiroshima, Japan in 1945. It used uranium-235 as its fissile material to trigger a nuclear chain reaction, resulting in a devastating explosion.
Either highly enriched uranium-235 or reactor produced plutonium.
In Hiroshima a uranium fission bomb was used and in Nagasaki a plutonium Implosion type bomb was used.
Uranium-235 or plutonium-239 are the two primary elements used to make an atomic bomb. These elements undergo fission reactions, releasing vast amounts of energy in the process.
Both uranium and plutonium were used extensively to make the first two atomic bombs, dropped on Hiroshima and Nagasaki, respectively.
The first atomic bomb used against mankind was dropped over Hiroshima, Japan on August 6, 1945. It's code name was little boy and it used Uranium as fuel. The second bomb was dropped over Nagasaki, Japan on august 9, 1495. It,s code name was fat man and it used Plutonium as fuel.
