At no time have nuclear weapons been in Cuba. In the 1963 Cuban missile crisis the USSR and Cuba had built IRBM launch facilities, IRBM storage facilities, and warhead storage facilities. Some IRBM's had been shipped to Cuba, but no warheads. The Soviet ships carrying warheads were stopped by the US Naval quarantine, then turned around.
During the Vietnam War, a nuclear bomb was found and successfully defused by American special forces.
The cores of stars and hydrogen bombs.
Protons and Neutrons in atomb bombs are found in the nuclear fission reaction.
It depends which type it is. It can be Uranium or Plutonium
Nuclear fusion has been used for nuclear transformation, which is the production of new materials by fusion, and for the type of specific type of transformation called nuclear synthesis, which is the production of materials not normally found in nature. It has been used in nuclear bombs, specifically fusion bombs or hydrogen bombs. There is hope that nuclear fusion can be used to provide power for generation of electricity, though this has not yet been achieved in a practical system. There is a link below to an article on nuclear fusion.
Californium is not typically used in nuclear bombs due to its high cost and limited availability. Nuclear bombs typically use plutonium or uranium as the fissile material for the explosive chain reaction. Californium is used more commonly in research and medical applications due to its ability to produce neutrons.
Hydrogen bombs usually use the element Lithium to produce Tritium in situ, but it is not in the reactive metallic form. It is in the form of Lithium Deuteride, so that when the Lithium is transformed to Tritium it is already in a Deuterium-Tritium mixture ready to undergo nuclear fusion.
Lt. Calley was found guilty of burning the village of Mei Lai.
Americium is not suitable for making fission-type nuclear bombs because it is primarily an alpha emitter, which means it does not release enough neutrons to sustain a chain reaction necessary for a nuclear explosion. Additionally, it is difficult to obtain enough pure americium for bomb production, as it is a rare element that is not found in large quantities.
