If An isotope of an element has a half life of ten years How long would it take for this isotope to decay to about onesixteen of its original amount?
It would take approximately 40 years for the isotope to decay to about one-sixteenth of its original amount. This is because each half-life reduces the amount by half, so after two half-lives (20 years) the amount would be reduced to one-quarter, and after three half-lives (30 years) it would be reduced to one-eighth, approaching one-sixteenth after four half-lives (40 years).
Tha half life of an atom is 50 years what is a possible exponential function for this decay?
A possible exponential decay function for this scenario would be P(t) = P0 * (0.5)^(t/50), where P(t) is the amount remaining after time t, P0 is the initial amount, and t is the time passed in years. This formula represents the decay of a substance with a half-life of 50 years.
How long would it take a radioactive isotope to decay if it has a half life of 10 years?
It would take 10 years for half of the radioactive isotope to decay, and another 10 years for half of the remaining amount to decay, and so on. The process continues until the isotope has decayed to a negligible amount, which typically takes around 5 half-lives, or 50 years in this case.
The half life of uranium 235 is 700 million years After 1.4 billion or 1 400 million years what fraction of the original amount of uranium 235 remains?
A half life pertains to the time it takes for exactly half of a substance to disappear. So, if U235 has a half life of 700 million years, it will take 700 million years for half of it to decay. That would leave .5kg or 500g.
How do you explain the half-time of a radioactive material?
The half-life of a radioactive material is the time it takes for half of a sample of the substance to decay. It is a characteristic property of the specific radioactive isotope and is used to determine the rate of decay and the stability of the material. The half-life can vary greatly depending on the isotope, ranging from fractions of a second to billions of years.
How long will it take for 2G of tritium to decay into 2Mg?
Tritium is an isotope of Hydrogen. It has one proton and two neutrons. It decays into Helium or He. It takes 12 1/2 years for half of the original amount to decay into helium. It does not decay into magnesium. So the answer to your original question is forever.
The half-life of cobalt-60 is 5.3 years After years 1 4 of the original amount of cobalt-60 will remain?
After 1 year, 50% of the original amount of cobalt-60 will remain. This means that 50% will decay and 50% will be left. After 4 years, 6.25% of the original amount (50% of 50%) of cobalt-60 will remain.
What does it mean by the statement The decay of unstable radioactive nuclei is totally random?
It means that you can't predict when an individual atom will decay. If a certain isotope has a half-life of 5000 years, that means that if you have a large number of atoms, half of them will decay after 5000 years. After another 5000 years, half of what is left will decay - only 1/4 of the original amount is left. For an individual atom, in the above example, there is a probability of 50% of decaying within 5000 years, a probability of 75% of decaying within 10,000 years, etc.
Why will the amount of a radioactive substance never reach zero amount present?
The total amount of radioactive substance will never reach zero because it decays in half-lives. For C-14 is 5730 years, this means that after 5730 years one half of the original material will have decayed. After another 5730 years the remaining radioactive material (1/2 the original) will have decayed by 1/2 once again. -An infinite crowd of mathematicians enters a bar. The first one orders a pint, the second one a half pint, the third one a quarter pint... "I understand", says the bartender - and pours two pints.
How long would it take for plutonium to decay to one eighth of its original activity?
For plutonium (or any other radionuclide) to decay to one eighth of its original activity, it will take 3 half-lives of the material. In one half-life, half is gone. Half will be left. In another half-life, half of the half that was left is gone, and one quarter will be left. In a third half-life, half the one quarter will be left, and that's one eighth of the original. In the case of plutonium, there are a number of isotopes of this highly radioactive stuff. The isotope 239Pu, which is commonly used in nuclear weapons, has a half-life of 2.41 x 104 years. That's 24,100 years. For 239Pu to decay to 1/8 th of its original amount, it will take 3 time the half-life, which is 7.23 x 104 years, or 72,300 years. And yes, that is a long time. A very long time....
If An isotope of an element has a half life of ten years How long would it take for this isotope to decay to about onesixteen of its original amount?
It would take approximately 40 years for the isotope to decay to about one-sixteenth of its original amount.

If 12.5 grams of the original sample of cesium-137 remained after 90.69 years what was the mass of the original sample?
To find the original mass of the cesium-137 sample, you can use the exponential decay formula: final amount = initial amount * (1/2)^(time/half-life). With the information provided, you would have: 12.5 = initial amount * (1/2)^(90.69/30.1). Solving for the initial amount gives you approximately 40 grams.
How long does it take for nuclear waste to decay completely?
Nuclear waste can take thousands to millions of years to decay completely, depending on the type of radioactive material.
After years 14 of the original amount of colbalt 60 will remain?
Cobalt-60 has a half-life of approximately 5.27 years, meaning that after this period, half of the original amount will have decayed. After 14 years, which is about 2.65 half-lives, the remaining amount can be calculated using the formula: remaining amount = original amount × (1/2)^(time/half-life). Therefore, after 14 years, approximately 1/6 of the original amount of cobalt-60 will remain.
How much of the original material is left after 4 billion years?

Tha half life of an atom is 50 years what is a possible exponential function for this decay?
A possible exponential decay function for this scenario would be P(t) = P0 * (0.5)^(t/50), where P(t) is the amount remaining after time t, P0 is the initial amount, and t is the time passed in years. This formula represents the decay of a substance with a half-life of 50 years.
What is half-life of a radioistope is the amount of time it takes for?
The time depends on the isotope. The half life of uranium-238 is about 4.47 billion years and that of uranium-235 is 704 million years. The half life is the amount of time during which any given atom of the isotope has a 50% chance of undergoing decay. Seen another way, the half life is the time it takes for half the atoms of an isotope in a mass of that isotope to undergo decay.
