answ2. Radioisotopes decay at a rate specific to the particular element (and its isotope). Carbon for example has two stable isotopes (C12 and C13), and another half-dozen or so of short-lived ones. C14 is a natural isotope with a half-life of around 5700 years, and is very useful for dating archaeological remains.
Tin for example has ten stable isotopes, and up towards 20 radioactive ones.
Many other isotopes are used for dating different items, and some even have half-lives in excess of the age of the Earth. For many purposes these may considered as stable.
Reverting to the carbon, after 5700 years, there is one-half of the C14 left that there was previously. After 11 400 years there would be a quarter of the original quantity and so on.
What else can I help you with?
How can one determine the relative velocity between two objects?
To determine the relative velocity between two objects, you can subtract the velocity of one object from the velocity of the other object. This will give you the relative velocity between the two objects.
Which 2 factors determine gravitational attraction between 2 objects?
The two factors that determine the gravitational attraction between two objects are their masses and the distance between their centers. The greater the mass of the objects, the stronger the gravitational force, and the closer the objects are to each other, the stronger the gravitational attraction.
What are the factors that determine the strength of gravity between two objects?
The factors that determine the strength of gravity between two objects are their masses and the distance between them. The greater the mass of the objects, the stronger the gravitational force. Additionally, the closer the objects are to each other, the stronger the gravitational force will be.
What two properties determine how strong of a force gravity will play on two objects?
The two properties that determine how strong of a force gravity will exert on two objects are the mass of the objects and the distance between their centers. The greater the mass of the objects, the stronger the gravitational force will be between them. Additionally, the closer the objects are to each other, the stronger the gravitational force will be.
What are two factors that determine an object's gravitational force on other objects?
The two factors that determine an object's gravitational force on other objects are the mass of the object and the distance between the objects. The greater the mass of an object, the stronger its gravitational force. Additionally, the closer two objects are to each other, the stronger the gravitational force between them.
What makes radioisotopes useful for dating objects?
They decay at a predictable rate.
What are the radioisotopes used in forensic science?
Some of the radioisotopes used in forensic science include carbon-14 (C-14) for radiocarbon dating of organic materials, strontium-90 (Sr-90) for identifying human remains based on dental records, and iodine-131 (I-131) for identifying thyroid disorders in individuals. These radioisotopes help forensic scientists determine the age of samples, establish human identity, and assess physiological conditions in individuals.
What are two uses of radioisotypes?
Radiometric dating is a common use of radioisotopes to determine the age of rocks, fossils, and archaeological artifacts. Radioisotopes are also used in medicine, such as in imaging techniques like PET scans and in cancer therapy.
Why are radioisotpoes important to biologists?
Radioisotopes are important to biologists because they can be used as tracers to study biological processes. By attaching a radioisotope to a molecule or element, scientists can track its movement through organisms or ecosystems, helping to understand metabolic pathways, nutrient cycling, and physiological functions. Radioisotopes are also used in radiometric dating to determine the age of fossils and archaeological remains.
Are radioisotopes salts?
Radioisotopes are not salts but salts may contain radioisotopes.
What is the function of radioisotopes C-14?
Used in carbon dating that is to find the age of fossils.
What are the two medical applications of radioisotopes?
- radiodiagnostic- treatment with radioisotopes
What method of archaeological dating determines an artifacts age in relation to other objects?
Relative dating methods, such as stratigraphy and seriation, determine an artifact's age by comparing it to other objects found in the same layer or context. By analyzing the position of the artifact within the site and its stylistic attributes, archaeologists can estimate its age in relation to other objects.
How is the age of the cave printing determine?
It is determined by carbon-dating ( sorry i don't know exactly how its typed ) the walls, bones or objects in the cave
What are two ways scientist determine age?
Scientists determine the age of objects or organisms through radiometric dating, which measures the decay of radioactive isotopes, or through dendrochronology, which analyzes the patterns of tree rings to determine age.
Harmful effects of radioisotopes?
Radioisotopes can emit harmful radiations that can cause cancer.
How many radioisotopes appeared after explosion on hiroshima and nagasaki?
About 3.2 Radioisotopes in both bombings.
