The definition of fission.
The reaction created when a neutron strikes the nucleus of an isotope and splits the nucleus.
The way J. Robert Oppenheimer is relate to the atomic bomb.
The (main) creator of the atomic bomb.
The place this bomb was first dropped.
Hiroshima
The place this bomb was first dropped.
Nagasaki
The reason fission is used in atomic bombs.
Provides the chain reaction that gives the bomb power.
The title often attributed to J. Robert Oppenheimer.
The "father of the atomic bomb".
The amount of people that died from this bomb.
70,000-126,000 people died.
The amount of people that died from this bomb.
39,000-80,000 people died.
The types of bombs that use fission.

When he was alive.
(1904-1967)
The style of bomb this is.
Gun-type
The style of bomb this is.
Implosion
The process of fission.
A neutron splitting the nucleus of an atom, which then releases more neutrons and continues the chain reaction.
The place and position he had while making the atomic bomb.
The director of the Los Alamos Laboratory during the Manhattan Project.
The four ways uranium was gathered for this bomb.
Gaseous diffusion, centrifuge, electromagnetic separation, and liquid thermal diffusion.
The reason a gun-type design would not work for this bomb.
Spontaneous fission would happen too soon.
The material of the tamper and why it is made of this.
U-238 because it will reflect the neutrons back to the the middle to encourage more fission.
The type of scientist he was.
An American theoretical physicist.
