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.


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.


The time it takes for 50 percent of the nuclei in a radioactive sample to decay to its stable isotope is called?

The time it takes for 50 percent of the nuclei in a radioactive sample to decay to its stable isotope is called the half-life of the radioactive element. It is a characteristic property of each radioactive isotope and can vary greatly among different elements.


How does carbon 14 find the age of an object?

Carbon-14 dating measures the amount of carbon-14 isotope in a sample. Carbon-14 is a radioactive isotope that decays at a known rate over time. By comparing the amount of carbon-14 in a sample to the amount of stable carbon isotopes, scientists can calculate the age of the object.


As a sample of a radioactive element decays its half-life?

The half-life of a radioactive element is the time it takes for half of the atoms in a sample to decay. As the sample decays, the number of radioactive atoms decreases while the number of stable atoms increases. The process continues in this manner, with each half-life reducing the amount of radioactive material by half.

Can the half life of a radioactive isotope decrease as the isotope decays?

No, the half-life of a radioactive isotope is a constant property of that particular isotope and does not change as it decays. The half-life is defined as the time it takes for half of the atoms in a sample to decay. Once set, the half-life remains constant regardless of how many atoms have decayed.


How is radiometric dating measured?

Radiometric dating is measured by analyzing the decay of radioactive isotopes in rocks and minerals. Scientists measure the ratio of parent isotopes to daughter isotopes to determine the age of a sample. By calculating the rate at which the parent isotope decays into the daughter isotope, the age of the sample can be estimated.

How does carbon dating work to determine the age of archaeological artifacts?

Carbon dating works by measuring the amount of radioactive carbon-14 in a sample. Carbon-14 is a radioactive isotope that decays at a known rate over time. By comparing the amount of carbon-14 in a sample to the amount in living organisms, scientists can determine the age of the artifact.
