Who helped make the first atomic bomb?
Too many to list by name (including my grandfather, who worked at the Hanford Site oiling machines from the summer of 1944 through February 1945, without ever having any idea of what the purpose of Hanford was or that its product was part of a very powerful bomb).
I know but its a secret
When did the Soviet Union make their first atomic bomb?
The US developed the first nuclear fission weapons (atomic bombs) during World War II as part of the Manhattan Project, a top-secret military program that saw several firsts i…n nuclear chain reaction experiments. Through the work of many international physicists and other experts, the US exploded the first a-bomb near Alamogordo, New Mexico on July 16, 1945. The following two bombs were used in August, 1945, against the Empire of Japan, destroying the cities of Hiroshima and Nagasaki.
Yes, Hiroshima bomb (Little boy)
for instance you could go and look in an encyclopedia instead of grovelling over the computer looking at my awnser you beg
The Soviet Union (Russia's predecessor) tested its first 'atomic bomb' on August 29th, 1949 "First Lightning" ( ÐÐµÑÐ²Ð°Ñ Ð¼Ð¾Ð»Ð½Ð¸Ñ). The first… mass produced atomic bomb rolled off the assembly line in 1953.
It was first dropped on people in Hiroshima, Japan, August 6th, 1945, then Nagasaki, Japan, August 9th, 1945, both by the US. However, the first test was in New Mexico (again …by the US), but there the people were told that it was going to happen.
Albert Einstein's assistance to the Manhattan Project was in the form of a letter he wrote to FDR, encouraging him to persue research in atomic weapons. Although Einstein was… a pacifist and was strongly opposed to war, he viewed Nazi-Germany as the greater threat and used his prestige as a physicist to encourage atomic research. As a Jewish-German, Einstein had seen first-hand what the Third Reich was willing to do, and did not want them being the sole owners of atomic weapons.
by dividing an atom leading to a microscopic domino effect creating into a large explosion.

Many, many countries helped in the Manhattan Project. . Robert J. Oppenheimer is usually credited with being the primary scientific leader of the U.S. Manhattan Project. How…ever, the project was an immense undertaking, and there were literally thousands of very smart scientists involved, and it would be a mistake to credit the technological advancements required to build the bomb to even a small group of them. Oppenheimer is usually noted because he headed the scientific portion of the Manhattan Project - he was the lead science administrator, and while he did make some interesting contributions, his primary job was administrative, rather than research. Leo Szilard and Albert Einstein brought concerns to the FDR Administration in August 1939 about the serious possibility of an atomic bomb being feasible, and the concern inside the scientific community that Germany might have the technological and scientific know-how to create such a weapon for use in the just-started WW2. Einstein, however, did not do any of the initial research in atomic fission, nor did he play any role in the Manhattan Project.
In Nuclear Weapons
Uranium -235 was used to make the first atomic bomb.

I believe you are referring to Albert Einstein.
The uranium enrichment plants were built at Oak Ridge, TN andpowered by cheap electricity generated by the Tennessee ValleyAuthority.
In Elements and Compounds
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.). Several metallic elements were used in the casing andelectronics including: aluminum , copper , iron , tungsten , etc. The vacuum tubes had glass envelopes( silicon and oxygen ) with bakelite plastic bases( carbon , hydrogen , and oxygen ). The batterywas a lead acid battery ( lead , sulfur , hydrogen , and oxygen ). Several other "minor"materials containing other elements were also present. The second atomic bomb used in combat (Fatman on August 9, 1945)was nearly identical to Gadget but had an external casing and RADARelectronics added using elements similar to Little Boy, butphysically shaped differently.

Many elements were used in the first atomic bombs in the nonnuclearparts. As I cannot possibly list them all (the most common elementswere the carbon, nitrogen, and oxygen use…d in the chemicalexplosives) I will only address the elements used as the nuclearfuel that powered the atomic explosion. .
