Answer . \nThe Target Committee at Los Alamos on May 1011, 1945, recommended Kyoto, Hiroshima, Yokohama and the arsenal at Kokura as possible targets. The committee rejected the use of the weapon against a strictly military objective due to the chance of missing a small target not surrounded b…y a larger urban area. The psychological effects on Japan were of great importance to the committee members. They also agreed that the initial use of the weapon should be sufficiently spectacular for its importance to be internationally recognized. The committee felt Kyoto, as an intellectual center of Japan, had a population "better able to appreciate the significance of the weapon." Hiroshima was chosen due to its large size, its being "an important army depot" and the potential that the bomb would cause greater destruction due to its being surrounded by hills which would have a "focusing effect".\n. \nSecretary of War Henry L. Stimson struck Kyoto from the list because of its cultural significance, over the objections of Gen. Leslie Groves, head of the Manhattan Project. According to Professor Edwin O. Reischauer, Stimson "had known and admired Kyoto ever since his honeymoon there several decades earlier." On July 25 General Carl Spaatz was ordered to bomb one of the targets: Hiroshima, Kokura, Niigata or Nagasaki as soon after August 3 as weather permitted, and the remaining cities as additional weapons became available.\n. \n. \n. \n. \nAt the time of its bombing, Hiroshima was a city of considerable industrial and military significance. Even some military camps were located nearby, such as the headquarters of the Fifth Division and Field Marshal Shunroku Hata's 2nd General Army Headquarters, which commanded the defense of all of southern Japan. Hiroshima was a minor supply and logistics base for the Japanese military. The city was a communications center, a storage point, and an assembly area for troops. It was one of several Japanese cities left deliberately untouched by American bombing, allowing an ideal environment to measure the damage caused by the atomic bomb. Another account stresses that after General Spaatz reported that Hiroshima was the only targeted city without POW-camps, Washington decided to assign it highest priority.\n. \n. \n. \nThe center of the city contained a number of reinforced concrete buildings and lighter structures. Outside the center, the area was congested by a dense collection of small wooden workshops set among Japanese houses. A few larger industrial plants lay near the outskirts of the city. The houses were of wooden construction with tile roofs, and many of the industrial buildings also were of wood frame construction. The city as a whole was highly susceptible to fire damage.\n. \n. \n. \nThe population of Hiroshima had reached a peak of over 381,000 earlier in the war, but prior to the atomic bombing the population had steadily decreased because of a systematic evacuation ordered by the Japanese government. At the time of the attack the population was approximately 255,000. This figure is based on the registered population used by the Japanese in computing ration quantities, and the estimates of additional workers and troops who were brought into the city may be inaccurate.\n. \n. \n. \nHiroshima was the primary target of the first U.S. nuclear attack mission, on August 6, 1945. The B-29 Enola Gay, piloted and commanded by Colonel Paul Tibbets, was launched from Tinian airbase in the West Pacific, approximately 6 hours' flight time away from Japan. The drop date of the 6th was chosen because there had previously been a cloud formation over the target. At the time of launch, the weather was good, and the crew and equipment functioned properly. Navy Captain William Parsons armed the bomb during the flight, since it had been left unarmed to minimize the risks during takeoff. In every detail, the attack was carried out exactly as planned, and the gravity bomb, a gun-type fission weapon, with 60 kg (130 pounds) of uranium-235, performed precisely as expected.\n. \n. \n. \n. \nAbout an hour before the bombing, the Japanese early warning radar net detected the approach of some American aircraft headed for the southern part of Japan. The alert had been given and radio broadcasting stopped in many cities, among them Hiroshima. The planes approached the coast at a very high altitude. At nearly 08:00, the radar operator in Hiroshima determined that the number of planes coming in was very smallprobably not more than threeand the air raid alert was lifted. (To save gasoline, the Japanese had decided not to intercept small formations, which were assumed to be weather planes.) The three planes present were the Enola Gay (named after Colonel Tibbets' mother), The Great Artiste (a recording and surveying craft), and a then-nameless plane later called Necessary Evil (the photographing plane). The normal radio broadcast warning was given to the people that it might be advisable to go to air-raid shelters if B-29s were actually sighted, but no raid was expected beyond some sort of reconnaissance. At 08:15, the Enola Gay dropped the nuclear bomb called "Little Boy" over the center of Hiroshima. It exploded about 600 meters (2,000 feet) above the city with a blast equivalent to 13 kilotons of TNT, killing an estimated 70,00080,000 people. At least 11 U.S. POWs also died. Infrastructure damage was estimated at 90% of Hiroshima's buildings being either damaged or completely destroyed. (MORE)

The United States' effort to develop a nuclear weapon came during World War II in response to the potential threat of a German nuclear weapon. On 6 December 1941, President Roosevelt appointed a committee to determine if the United States could construct a nuclear weapon. Six months later, the commi…ttee gave the President its report, recommending a fast-paced program that would cost up to $100 million and that might produce the weapon by July 1944 (1: 12,13). The President accepted the committee's recommendation. The effort to construct the weapon was turned over to the War Department, which assigned the task to the Army Corps of Engineers. In September 1942, the Corps of Engineers established the Manhattan Engineer District (MED), under the command of Major General Leslie Groves, to oversee the development of a nuclear weapon. This effort was code named the "Manhattan Project" (1: 13). During the first 2 years of the Manhattan Project, work proceeded at a slow but steady pace. Significant technical problems had to be solved, and difficulties in the concentration of uranium-235 and production of plutonium, particularly the inability to process large amounts, often frustrated the scientists. Nonetheless, by 1944 sufficient progress had been made to persuade the scientists that their efforts might succeed. A test of the plutonium implosion device was necessary to determine if it would work and what its effects would be. Led by Dr. J. Robert Oppenheimer, Manhattan Project scientists at Los Alamos Laboratory (later to become the Los Alamos National Laboratory) were "to make preparations for a field test in which blast, earth shock, neutron and gamma radiation would be studied and complete photographic records made of the explosion and any atmospheric phenomena connected with the explosion" (MORE)
Trinity test device was Plutonium fueled. . Hiroshima gravity bomb was Uranium fueled. . Nagasaki gravity bomb was Plutonium fueled.
The first atomic bomb was exploded in the middle of a desert in New Mexico. You are probably thinking of the test explosion done after World War II at Bikini Atoll in the Pacific.
either uranium or plutonium may be used in fission bombs, hydrogen and/or lithium may be used in fusion bombs.

There are many different elements involved in the construction of an atomic bomb, but the elements that actually cause an atomic explosion are either uranium (specifically the U 235 isotope) or plutonium.
Because the bomb wasn't ready until after Germany surrendered. Germany surrendered on 8 May 1945, and the first successful test of an operational nuclear weapon did not take place until 16 July 1945.
The first atomic bomb detonated was not dropped, it was hung from the top of a steel structure and detonated remotely.

The first atomic bomb tested (Gadget on July 16, 1945) used plutonium as the fission fuel alloyed with gallium and beryllium and polonium in the neutron sourceinitiator. Two explosive mixtures called Composition B and Baratolwere used in the explosive lenses that imploded the plutonium tomake …it supercritical (these explosives contained many elementsincluding: carbon , hydrogen , nitrogen , oxygen , barium , etc.). Several metallic elements wereused in the casing and electronics including: aluminum , copper , iron , tungsten , etc. The vacuum tubeshad glass envelopes ( silicon and oxygen ) withbakelite plastic bases ( carbon , hydrogen , and oxygen ). The battery was a lead acid battery ( lead , sulfur , hydrogen , and oxygen ). Several other"minor" materials containing other elements were also present. The first atomic bomb used in combat (Little Boy on August 6, 1945)used enriched uranium as the fission fuel and beryllium and polonium in the neutron sourceinitiator. The smokeless propellant Cordite was used in the gunthat fired the the two pieces of uranium together to make itsupercritical (Cordite contained many elements including: carbon , hydrogen , nitrogen , oxygen ,etc.).

The first atomic bomb (The Gadget) was not used on any city. It wasdetonated on the top of a 100 foot tall steel tower, at the TrinitySite in the Jornada del Muerto desert about 35 miles southeast ofSocorro, New Mexico, on what was then the USAAF Alamogordo Bombingand Gunnery Range (now part of Whit…e Sands Missile Range) on July16, 1945. The second atomic bomb (Little Boy) was the first to be used on acity. 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 atomicbomb used on a city). It was dropped by a B-29 above Nagasaki Japanon August 9, 1945. The fourth atomic bomb (unnamed, identical to Fatman) had beenmanufactured by Los Alamos shortly after Fatman was used onNagasaki and shipped to San Francisco, where a B-29 was waiting tofly it to Tinnian for use in a third attack on Japan sometime inlate August. However as the Japanese indicated that they wouldsurrender before this bomb arrived in San Francisco, presidentTruman issued an order that it be returned to Los Alamos instead ofbeing loaded on the B-29 for Tinnian. All together the US had plans, facilities, and aircraft tomanufacture and deliver a total of 23 atomic bombs onJapanese cities before the end of 1945: .
