It seductivly strokes a girls cheek, then leans in close to her ear and whispers "baby, be my girl..." then she dates it! easy peasy lemon squeezy!
uranium-235 dates older objects so uranium-235 would be your answer
Uranium-235 was used in the atomic bomb dropped on Hiroshima.
Uranium-235 is the element with a mass number of 235. It is a radioactive isotope of uranium that is used in nuclear reactors and nuclear weapons.
Uranium-235 (235U)
Uranium is a chemical element with three natural isotopes (234, 235, 238). The natural uranium has cca. 0,72 % uranium-235; uranium with a concentration of uranium-235 under 0,72 % is called depleted uranium; uranium with a concentration of uranium -235 above 0,72 % is called enriched uranium. Uranium in nuclear power and research reactors is used as metal, aloys, uranium dioxide, uranium carbides, uranium silicides, etc.
Uranium-235 and uranium-238 are isotopes of uranium, meaning they have the same number of protons but different numbers of neutrons. Uranium-235 is used in nuclear reactors and weapons due to its ability to sustain a nuclear chain reaction, while uranium-238 is more abundant in nature but less useful for these purposes.
Not "Fat boy" but "Fat man'; "Fat man" had putonium, not uranium 235.
Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium.
Approx. 0,7 % uranium 235 in natural uranium.
Minimum one atom of uranium 235.
Yes, the Hiroshima bomb was with uranium 235.
When uranium-235 is added to natural uranium, it increases the overall percentage of uranium-235 in the mixture. This can make the uranium more suitable for use in nuclear reactors or weapons, as uranium-235 is more fissile (more easily split by neutrons) than uranium-238.
