What are the half lives for uranium-235 and uranium-238?
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.
What is the half life of power grade uranium?
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.
How long can radioactivity be on uranium?
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.
Uranium-235 has a half life of?
The half-life is 700 million years !
How is Uranium-235 different from the average uranium atom?
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.
What is the half life uranium-235?
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.
What are the half lives for uranium-235 and uranium-238?
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.
What does Half-Life of Uranium 235 mean?
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.

What factors should Margaret NOT consider when deciding what ingredients to add to her punch?
The half life of Uranium 235
Uranium-235 has a half-life of 700 million years. how long does it take a 100-gram sample of uranium-235 to decay to a mass of 50 grams?
700 million (more exactly 703,8.106) years
How long does it take a 5-gram sample of uranium- 235 to decay to a mass of 2.5 grams?
One Half-Life :-)
Uranium-235 has a half life of?
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.
If a rock sample originally contained 12 g of Uranium-235 how much will be left after 1 half life?
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.
Uranium-235 has a half-life of 700 million year. how long does it take a 100 gram sample of uranium to decay to a mass of 50 grams?
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/
