What is the similarity of radioactive isotope and radioactive dating?

Radioactive isotopes are used for radioactive dating. For example, you would use radioactive isotope Carbon-14 to date anything under 70,000 years that was once living. Radioactive isotopes decay from their parent isotope to daughter isotope at a constant rate (under any circumstances). The rate at which a parent isotope decays to its daughter isotope is considered one half life. Carbon-14 has a half life of 5730 years and its daughter isotope is Nitrogen-14. In order to determine how old something is you have to find out how much of the parent isotope is present in relation to the daughter.


What is the rate in halflife that radioactive decay occurs?

Half-life is the time it takes for one half of a certain type of atom (isotope) to decay. The amount of time varies a lot between different isotopes; in some cases it may be a fraction of a second, in another, it may be billions of years.


How are radioactive isotopes used determine the absolute age of igneous rock?

Answer : When the isotopes decay, scientists can find out how old the rock is depending on the radioactive isotope's half-life. Explanation: Radioactive isotopes are unstable and will decay. For example, when humans die carbon-14 decays. The isotopes will decay into a stable isotope over time. Scientists can tell how old the rock was from looking at the radioactive isotope's half-life, which tells them how long it would take for there to be half the radioactive isotope and half the stable isotope. At the next half-life there will be 25% of the radioactive isotope and 75% of the stable isotope. At the next half life there will be 12.5% radioactive and 87.5% stable. Example: Carbon-14 is a radioactive isotope with a half life of 5,730 years. How old would carbon-14 be when there is 75% carbon-14 in the rock? 75% is half of the time before the half-life, so it would be 2,365 years. Hope this helps. Half life helps scientists find how much the isotope has decayed and the age of the rock.


What is C-14?

Carbon-14 (C-14) is a rare isotope of carbon produced in the upper atmosphere when a cosmic ray strikes an atom of nitrogen. Carbon-14 is radioactive undergoing beta decay to nitrogen-14 with a halflife of 5570 years. Because it is produced at a near constant rate and living organisms maintain the same percentage of it as is present in the atmosphere while they are alive, but after an organism dies it can no longer equalize the amount of the carbon-14 in its tissues, this isotope's decay can be used as a "clock" to measure the time since the organism died.


What is non-radioactive?

Every stable isotope is non radioactive. That is the definition of "stable." It is possible protons have a half life, but if so it exceeds 6.6 decillion years. Hydrogen and deuterium are stable. Tritium (H3) has a half life of about 12 years.

What is the half life of the radioactive isotope?

The half life is the period of time it takes radioactive decay to transmute one half of the isotope present at the start of the period to a different isotope, usually an isotope of a different element. This period of time is different for different isotopes, with known isotope half lives ranging from femtoseconds to many billions of years.
