To determine the age of a rock sample that contains a parent isotope with a half life of 100 million years and contains 132 of the parent isotope?
To determine the age of the rock sample, you would need to know the amount of the daughter isotope present, as this allows you to calculate how many half-lives have passed. Since the half-life is 100 million years, you can use the formula ( N = N_0 \times (1/2)^{t/T} ), where ( N ) is the remaining parent isotope, ( N_0 ) is the initial amount, ( t ) is the age of the rock, and ( T ) is the half-life. If you only know the current amount of the parent isotope (132), you need the initial amount to proceed with the calculation.
What else can I help you with?
Which measurement would help determine absolute dates by radiometric means?
The measurement of the ratio of parent isotope to daughter isotope would help determine absolute dates by radiometric means. This ratio provides a way to calculate the age of a sample based on the known decay rate of the parent isotope into the daughter isotope.
What happens to the amount of parent isotope in a rock with time?
The amount of parent isotope in a rock decreases with time as it decays into daughter isotopes. This is known as radioactive decay, and the rate of decay is constant for a particular parent isotope. By measuring the ratio of parent to daughter isotopes, scientists can determine the age of the rock using radiometric dating techniques.
The expression used to determine the correct age of the lava flow is the product of?
The expression used to determine the correct age of the lava flow is the product of the parent isotope's half-life and the ratio of parent isotope to daughter isotope in the sample. This is based on the principles of radiometric dating, where the decay of radioactive isotopes can be used to estimate the age of a rock or mineral.
What is a parent isotope?
These terms apply to the decay of radionuclides. The parent isotope is 'the starting point' of a decay series that when it decays, by giving off radiation, changes into another element, or isotope of the original element (the daughter isotope). For example: When Uranium 238 (parent isotope) decays and gives off an alpha particle, it transmutes into Thorium 234 (the daughter isotope).
What is the difference between the parent isotope and the daughter isotope?
The parent isotope is the original radioactive isotope that undergoes decay to form the daughter isotope. The daughter isotope is the stable isotope that is formed as a result of the radioactive decay of the parent isotope.

The daughter isotope is 87.5 percent if the half-life of the isotope is 150 million years how old is the sample?
To find the age of the sample, we need to determine how many half-lives have passed based on the daughter isotope percentage. Since the daughter isotope is 87.5% present, it means 12.5% has decayed from the parent isotope. Since 1 half-life would result in 50% decay, we can divide 12.5% by 50% to get 0.25 half-lives. Therefore, the sample is approximately 150 million years (half-life) x 0.25 = 37.5 million years old.
Which percentage replaces letter x of the parent isotope per half-time of a radioisotope?
The percentage of the parent isotope remaining after one half-life of a radioisotope is 50%. This means that half of the parent isotope has decayed into the daughter isotope.

What is the stable produced by the radioactive decay of a parent isotope?
daughter isotope
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.
What changes in an isotope as compared to its parent element?
An isotope differs from its parent element in the number of neutrons in its nucleus, which can affect its stability and properties.
What is the processes where an unstable parent isotope becomes a stable daughter isotope called?
The process where an unstable parent isotope becomes a stable daughter isotope is called radioactive decay. During this process, the parent isotope undergoes a series of transformations, such as alpha or beta decay, emitting particles or energy until it reaches a stable state as a daughter isotope.
Is a parent isotope more radioactive then a daughter isotope?
The daughter isotope is the result of the radioactive disintegration of the parent isotope. For example radium is a product of the uranium disintegration.The two isotopes have different chemical (different atomic numbers, etc.), physical and nuclear properties.
