Does a radioactive isotope decay at a varying rate from the time it forms?
The probability of decay of any particular atom is a constant. However, as time passes, the there are fewer atoms left to decay. So in that respect the number of decay event falls.
How is tossing a coin similar to radioactive decay of an element?
If you toss a coin, there are fifty percent chances of getting the head or tail. In the radioactive decay also fifty percent atoms will brake down. When you toss the coin next time, you have 25 percent chances of getting the head or tail repeated. Same is the case with radioactive material. you will be left with 25 percent of the radioactive material after half life. Third time the chances of getting the same head or tail is 12.5 percent. Here you are left with 12.5 percent of the radioactive material left with after another half life.
Heat that drives mantle convection comes from?
The heat that drives mantle convection primarily comes from the decay of radioactive elements within the Earth's mantle and core. This process releases heat that generates thermal gradients, causing material to move within the mantle. The heat may also originate from the residual heat left over from the Earth's formation.
At what point do isotopes stop decaying?
Isotopes do not stop decaying. The process of radioactive decay continues until the isotope reaches a stable state, which could be a different isotope or a non-radioactive element. The rate of decay can vary depending on the specific isotope.
What fraction of a radioactive sample decays after three half lives?
If I take a radioactive sample of 400 moles of an unknown substance and let it decay to the point of three half-lives I would have 50 moles left of the sample. 1/2 of what is left will decay in the next half-life. At the end of that half-life I will have 25 moles left of the unknown substance or 4/25.

When does an isotope undergo Decay?
An atom of a given isotope will undergo radioactive decay whenever it feels like it. No joke. The nucleus of a radioactive isotope is unstable. Always. But that atom has no predictable moment of instability leading immediately to the decay event. We use something called a half life to estimate how long it will take for half a given quantity of an isotope to undergo radioactive decay until half the original amount is left, but this is a statistically calculated period. No one knows how long it will take a given atom of a radioactive isotope to decay, except that those with very short half lives will pretty much disappear relatively quickly.
When an atom undergoes radioactive decay when does it become a completely different element?

What is the difference between radioactive decay and radiometric decay?
It is the difference between sand running out of an hour glass and determining what time it is by how much sand is left. Radioactive decay happens at a steady rate. If you can determine how much of that radioactive isotope ought to have been in a sample at the start and you can measure how much is left, you can tell how much time has passed.
When radioactive decays stop?
It will stop when there is nothing left to decay. There is basically no way to stop certain nuclides (isotopes) from decaying.
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.
The half-life of an isotope is the time required for half the nuclei in a sample to?
Half-life is the length of time required for half the atoms in a radioactive sample to decay to some other type of atom. It is a logarithmic process, i.e. in one half-life, there is half the sample left, in two half-lives there is one quarter the sample left, in three half-lives there is one eight left, etc. The equation is... AT = A0 2 (-T/H) ... where A is activity, T is time, and H is half-life.

The nucleus or atom left behind when a nucleus disintegrates or splits is?
Sometimes radioactive
What is the difference between radioactive decay and radiometric dating?
It is the difference between sand running out of an hour glass and determining what time it is by how much sand is left. Radioactive decay happens at a steady rate. If you can determine how much of that radioactive isotope ought to have been in a sample at the start and you can measure how much is left, you can tell how much time has passed.
What happens to a radioactive material over time?
It disintegrates into its daughter nuclei that are much more stabler than the radioactive nuclei. If a sample of radioacictive material is left it will decay into another element over a period of time. Note that complete decay is not possible. A fraction of the original radioactive material will always remain in the sample.
