E. None of above
Check Answer
The correct answer is A) 92U-235.
Uranium is a naturally occurring element that can exist in different isotopes, which have the same number of protons in the nucleus but a different number of neutrons. One isotope of Uranium that is used in nuclear weapons is U-235, which makes up about 0.7% of natural uranium. It is a fissile isotope, which means that it can sustain a chain reaction of nuclear fission when it absorbs a neutron. This property is what makes it useful in nuclear weapons, as well as in nuclear power plants. U-235 is a relatively rare isotope, so it is typically enriched to increase its concentration before it is used in a nuclear weapon.
The process of isotope separation is commonly used to enrich the Uranium to increase the U-235 percentage. The other isotopes of Uranium, U-234, U-238, are not fissile and cannot sustain a chain reaction, they are used as a fuel in Nuclear power plants, where they undergo nuclear fission, which generates heat and electricity.
