What happens to the amount of parent isotope in a rock with time What happens to the amount of daughter isotope?
As time passes, the amount of the parent isotope in a rock decreases due to radioactive decay. Simultaneously, the amount of the daughter isotope increases as it is produced from the decay of the parent isotope. This process continues until the parent isotope is significantly depleted and the daughter isotope accumulates to a stable level. Eventually, the ratio of parent to daughter isotopes can be used to determine the age of the rock through radiometric dating.
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 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.
. Describe in a few sentences how scientists use radioactivity to determine the age of a rock.?
Scientists use radioactivity to determine the age of a rock through a process called radiometric dating. They measure the amount of radioactive isotopes present in the rock and the rate at which they decay into stable isotopes. By comparing the ratio of parent isotope to daughter isotope, scientists can calculate the age of the rock based on the known half-life of the radioactive isotope.
How can radioactivity be used to to date rocks?
Radioactivity can be used to date rocks through a technique called radiometric dating, which measures the decay of radioactive isotopes within the minerals of the rock. When a rock forms, it contains a certain amount of a radioactive isotope, which decays into a stable daughter isotope at a known rate, known as its half-life. By measuring the ratio of the parent isotope to the daughter isotope in a rock sample, scientists can calculate the time that has elapsed since the rock was formed. This method is particularly useful for dating igneous and metamorphic rocks.

Why are igneous rocks the best type of rock sample for radiomertic dating?
Because when they form, minerals in igneous rocks often contain only a parent isotope and none of the daughter isotope. This makes the isotope percentage more accurate and easier to interpret.
How do scientist use Radioactive Isotopes to find the absolute age of a rock?
Scientists use radioactive isotopes in rocks to calculate their absolute age through a process called radiometric dating. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can determine how much time has passed since the rock formed. The rate of decay of the parent isotope into the daughter isotope provides a clock that allows scientists to calculate the rock's age.
How do scientist find the absolute age of a rock?
Radioisotopes are used by scientists to date rocks in a method called radiometric dating. The isotopes of an element are the atoms that have the same number of protons and electrons but different numbers of neutrons. When atoms of a radioactive isotope are included in the formation of a crystal, that crystal becomes the parent isotope. As the isotopes begin to decay, they become a daughter isotope. The convenient property of this phenomenon is that a certain parent isotope will ALWAYS decay to a certain daughter isotope. The rate of decay from parent to daughter isotope is called the half-life (time for half of the parent to become the daughter). Being familiar with and using isotopes such as Uranium-238, Uranium-235, and Carbon-14, scientists are able to calculate the age of a rock, fossil, etc. using the known half-life for each parent isotope.
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 does a scientist need to know to figure out the absolute age of rock?
They need to determine the amount of radioactive decay of a specific isotope in the rock since its formation.
Method of dating rock when the amount of parent and daughter materials are measured?
radiometric
Explain how radiometric dating is used to estimate absolute age?
Radiometric dating is based on the principle that certain isotopes decay at a constant rate over time. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can calculate how much time has passed since the rock formed. This method provides an accurate estimate of the absolute age of the rock or fossil.
