How many years will it take for 10g of radioactive uranium to decay into 5g of radioactive uranium?
Depending on the isotope: - for 235U: 7,038.108 years - for 238U: 4,468.109 years etc.
A specimen of uranium has half-life of 4.5 billion years How many years will it take one gram of this uranium to become 0.25 grams?
Approx. 9 billion years.
How many years will it take for 10 g of radioactive uranium to decay into 5 g of radioactive uranium?
It would take one half-life for the 10 g of uranium to decay into 5 g. The half-life of uranium is around 4.5 billion years, so it would take approximately 4.5 billion years.
How many years will it take for 10g of radioactive uranium to decay i to 5g of radioactive uranium?
The decay of radioactive materials follows an exponential decay model, characterized by the half-life. For uranium, the specific half-life depends on the isotope in question. However, to go from 10g to 5g of uranium, it would take one half-life, as this represents a reduction by half. The exact time in years would depend on the half-life of the specific uranium isotope being considered.
How many years in 3.5 years?
Three and a half years.
How many half lifes has uranium 238 undergone if it crystallized at the same time earth formed?
Uranium-238 has a half-life of about 4.5 billion years. The Earth is estimated to be about 4.5 billion years old, so if uranium-238 crystallized at the same time the Earth formed, it would have undergone approximately one half-life since then. This means that about half of the original amount of uranium-238 would remain today.
What is halflife of uranium?
Uranium has 29 natural and artificial isotopes. Each isotope has his specific half life; for the natural isotopes the half lifes are: U 234: approx. 2.45 x 105 years U 235: approx. 7.04 x 108 years U 238: approx. 4.46 x 109 years
How many years are 14 seasons?
Three and a half years.
600 grams of uranium after 3 half lives how many grams would there be?
1 ounce and three large testes
How many years to get a degree in temple university?
Three and a half years
How many years will it take for uranium-235 to go through 3 half lives?
[(7,038 ± 0,005) .108 years] x 3
How many years would it take for half of the atoms in uranium to change into lead?
The half-life of 214Bi is 19.7 minutes. However, it has two decay modes, neither of which leads directly to lead; that complicates things. One of the decay modes leads to 214Po, which then quickly (half-life 0.0016 seconds) decays to 210Pb. The other one leads to 210Tl, which has a half-life of 1.3 minutes and also decays to 210Pb. So: Half of the 214Bi will be gone in 19.7 minutes; a bit after that half the sample will be 210Pb.
