The half-life of uranium-235 is approximately 703.8 million years, while the half-life of uranium-238 is approximately 4.5 billion years.
The half-life of Power Grade Uranium (U-235) is approximately 703.8 million years. This means that it takes that amount of time for half of the radioactive material to decay into a stable element.
Radioactivity can persist on uranium for billions of years, as uranium has a very long half-life. The most common isotope of uranium, uranium-238, has a half-life of about 4.5 billion years. Uranium-235, another isotope, has a shorter half-life of about 700 million years.
The half-life is 700 million years !
Uranium-235 is a specific isotope of uranium that is slightly lighter than the average uranium atom. It is the only naturally occurring isotope that is fissile, meaning it can sustain a nuclear chain reaction. This makes uranium-235 important for nuclear power generation and weapons.
The half-life of uranium-235 is approximately 703.8 million years. This means that it takes that amount of time for half of a sample of uranium-235 to undergo radioactive decay.
The half-life of uranium-235 is approximately 703.8 million years, while the half-life of uranium-238 is approximately 4.5 billion years.
The half-life of Uranium 235 refers to the time taken for half of a sample of Uranium 235 atoms to undergo radioactive decay. It is a measure of the stability of the isotope, with Uranium 235 having a half-life of about 700 million years. This property is important in dating geological samples and in nuclear energy applications.

Uranium-235 is a specific isotope of uranium that is slightly lighter than the average uranium atom. It is the only naturally occurring isotope that is fissile, meaning it can sustain a nuclear chain reaction. This makes uranium-235 important for nuclear power generation and weapons.
After one half life, half of the original Uranium-235 will have decayed. So, 6 g of Uranium-235 will be left in the rock sample.
If a radioactive isotope has a half-life of 4 years, than 0.125 (0.53) of the isotope will remain after 12 years, or 3 half-lives.The question asked about Uranium. There is no isotope of Uranium with a half-life of 4 years. The closest is 232U92, which has a half-life of 68.9 years.Reference: http://www.nndc.bnl.gov/chart/
