Which isotope is the daughter element?
One example of this is uranium (atomic number 92) decaying into thorium (atomic number 90). The daughter isotope may be stable or it may decay to form a daughter isotope of its own….Thorium series.

What does it mean to be a parent isotope?
daughter isotope
A parent isotope is the isotope that decays, forming the daughter isotope after releasing a decay particle.
How do you calculate daughter isotopes?
Radiometric Dating – Graphical Method For example, after one half-life 0.5 of the original parent isotope remains, 0.5 of the sample is now the daughter isotope. After two half-lives 0.25 of the original parent isotope remains, 0.75 of the sample is now the daughter isotope.
Is carbon-14 a parent isotope?
Like other unstable isotopes, carbon-14 breaks down, or decays. The original atoms are called the parent isotopes. For carbon-14 decay, each carbon-14 atom loses an beta particle. It changes to a stable atom of nitrogen-14.
What are parent and daughter atoms?
In radioactive decay reactions, the unstable isotope is referred to as the parent and the element produced by the decay reaction is called the daughter. For each atom of a radioactive isotope there is a fixed and constant probability that it will decay in a fixed period of time.
Which element is the parent isotope?
As a Parent isotope decays, it slowly forms into a daughter isotope. For example, uranium is a parent isotope and as it decays, it turns into a daughter isotope, which is lead.
What is Rubidium-87 daughter isotope?
RADIOMETRIC TIME SCALE
| Parent Isotope | Stable Daughter Product | Currently Accepted Half-Life Values |
|---|---|---|
| Thorium-232 | Lead-208 | 14.0 billion years |
| Rubidium-87 | Strontium-87 | 48.8 billion years |
| Potassium-40 | Argon-40 | 1.25 billion years |
| Samarium-147 | Neodymium-143 | 106 billion years |
Why is a daughter isotope important?
Radiogenic isotopes The transmutation of elements due to radioactive decay is another important cause of isotope abundance variations. The abundance determination of radiogenic daughter isotopes is applied extensively for age determinations of geological and organic materials.
What is the daughter isotope of carbon 14?
nitrogen-14
For carbon-14 decay, each carbon-14 atom loses an beta particle. It changes to a stable atom of nitrogen-14. The stable atom at the end is the daughter product (Figure below).
What is an example of a parent daughter combination?
A common “parent-daughter” combination that geologists use is radioactive uranium and non-radioactive lead. As shown in the diagram above, uranium is trapped in a newly formed rock. As the rock ages, more and more of the uranium changes into lead.
Is nitrogen-14 a daughter isotope?
It changes to a stable atom of nitrogen-14. The stable atom at the end is the daughter product (Figure below). Unstable isotopes, such as carbon-14, decay by losing atomic particles.
What is the definition of daughter isotope?
Daughter Isotope Definition: The product which remains after an original isotope has undergone radioactive decay. The original isotope is termed the ‘parent’.
What is the definition of parent isotope?
A parent isotope is a radioactive form of an element that undergoes decay and produces daughter isotopes, which may in turn decay to produce other daughter isotopes.
What are daughter atoms?
Parent and Daughter Isotopes. The initial isotope is called the parent isotope, while the atoms produced by the reaction are called daughter isotopes. More than one type of daughter isotope may result. As an example, when U-238 decays into Th-234, the uranium atom is the parent isotopes, while the thorium atom is the daughter isotope.
What is a daughter atom?
The daughter of a daughter isotope is sometimes called a granddaughter isotope. The time it takes for a single parent atom to decay to an atom of its daughter isotope can vary widely, not only between different parent-daughter pairs, but also randomly between identical pairings of parent and daughter isotopes.
