Is it possible to determine exactly when a particular unstable isotope will begin to decay?
No. The time it will take for an individual unstable atom to decay is completely random and impossible to predict. However, because there are so many atoms in a sample (6.02x1023 in one mole) it is possible to observe the half-life of the atoms. The half-life is the time that it will take for half of the atoms in a sample of a radioactive isotope to decay into another element or isotope. This is a constant property of the isotope and does not depend on the sample size.
How do you identify beta decay?
A sample of 187 rhenium decays to 187-omium with halflife of 41.6 billion years. If all 188 osmium are normalized isotopes.
If the isotope have short half lives is that mean that the isotope is in a stable condition?
No. Only radioactive elements have half-lives, the half-life is the time that it will take for half of the atoms in a sample of a radioactive isotope to decay into another element or isotope. This is a constant property of the isotope and does not depend on the sample size. Stable isotopes never decay.
How does the length of the half-life of the element correspond to the radioactivity of the element?
The length of time required for half of a sample of radioactive material to decay
How long will it take a g sample of bismuth to decay such that 2.0 g of the element remains?
You forgot to say that isotope is.
Is it true that the half-life of a radioactive isotope decreases as the isotopes decay?
no, halflife is a constant for each isotope's decay process.
What is relative decay?
Relative decay is the process of determining the age of a sample by comparing the amount of a radioactive isotope it contains to the amount of its decay products. By measuring the ratio of remaining isotope to decay product, scientists can estimate the age of the sample based on the known decay rate of the isotope.
What is the characteristic time for the decay of a radioactive isotope?
The characteristic time for the decay of a radioactive isotope is known as its half-life. This is the time it takes for half of the radioactive atoms in a sample to decay.
What is half life of a isotope?
The half life of an isotope refers to the rate at which a radioactive isotope undergoes radioactive decay. Specifically, it is the amount of time it takes for half of a given sample of a radioactive isotope to decay.
How long will it take half of a radioactive sample to decay?
The time it takes for half of a radioactive sample to decay is known as the half-life. Each radioactive element has a unique half-life, which could range from fractions of a second to billions of years. The half-life remains constant regardless of the size of the initial sample.
How can you determine if an isotope is stable?
Isotopes are considered stable if they do not undergo radioactive decay. This can be determined by measuring the isotope's half-life, which is the time it takes for half of the atoms in a sample to decay. If the half-life is long, the isotope is considered stable.
How do scientists use the halflife of radioactive isotopes to date rocks and fossils?
The basic idea is to compare the abundance of a naturally occurring radioactive isotope within a material to the abundance of its decay products; it is known how fast the radioactive isotope decays.
Is it possible to determine exactly when a particular unstable isotope will begin to decay?
No. The time it will take for an individual unstable atom to decay is completely random and impossible to predict. However, because there are so many atoms in a sample (6.02x1023 in one mole) it is possible to observe the half-life of the atoms. The half-life is the time that it will take for half of the atoms in a sample of a radioactive isotope to decay into another element or isotope. This is a constant property of the isotope and does not depend on the sample size.
The time required for half of a sample of a radioactive isotope to break down by radioactive decay to form a daughter isotope.?
its called Half-Time...
A substance is the time required for half the atoms in a sample of a radioactive isotope to decay?
The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.
Does the size of a radioactive sample affect half-life?
No, the size of a radioactive sample does not affect its half-life. The half-life is a characteristic property of a radioactive isotope, defined as the time it takes for half of the radioactive atoms in a sample to decay. This property is intrinsic to the isotope itself and remains constant regardless of the amount of material present. Thus, whether you have a small or large sample, the half-life will remain the same.
What is the amount of time it takes for three fourthsof a radioactive sample of an isotope of bromine to decay if the half life of the isotope is 16.5 hours?
It takes one half-life for half of the radioactive sample to decay. Since half of the sample has decayed after 16.5 hours, it will take another 16.5 hours for the remaining half to decay, totaling 33 hours to decay three fourths of the original sample.
