The half-life of carbon-14 is about 5700 years. Some sources say 5730, but I don't know the accuracy of that number. In the case of carbon-14, this is the period of time for half the original material to decay to nitrogen-14. This is useful in carbon dating, where the ratio of carbon-14 to carbon-12 and carbon-13 is measured, giving an estimate for the age of a carboniferous (plant material) sample.

What do scientists call the time it takes for half of the radioactive atoms to change into daughter elements?
Scientists refer to the time it takes for half of the radioactive atoms to change into daughter elements as the half-life of the radioactive substance.
What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
How many protons neutrons and electrons are in carbon14?
7 protons, 7 neutrons and 7 electrons
An artifact is found that some are claiming is 30000 years old 3.1 percent of the original carbon14 is present The halflife of carbon14 is 5730 year?
To determine the age of the artifact, you can use the formula for exponential decay of radioactive elements: (N = N_0 \times (1/2)^{t/T}), where N is the final amount (3.1% of the original), N0 is the initial amount (100%), t is the time passed, and T is the half-life (5730 years). By substituting the values, you can solve for t, which will give you the age of the artifact.
What is an isotope that the time it takes it to decay to half its original mass?
c.half-life
What Limitations are there of using carbon14 to date rocks?
The main limitations of using Carbon14 dating to find the age of something that is carbon base are firstly the possibility that carbon may be absorbed by some things making it more difficult to get an absolutely accurate age and secondly, with Carbon14 only having a half life of 5,568 years the maximum theoretical limit for detection is 100,000 years.
What percent of carbon14 is left after 5 half-lives?
After 5 half-lives, 3.125% of the original carbon-14 would remain. Each half-life reduces the amount by half, so after 5 half-lives, it would be reduced by a factor of 2^5 = 32.
A researcher who uses carbon dating on anciet items?
The half life of C14 is about 5700 years, so items that are a few multiples of this time are suitable for carbon14 dating. Most archaeological items are suitable, and some young fossils.
What is the Half life of illicit drugs?
it depends on the drug. the cut, and the form in which it is administered. YOU WILL NOT KNOW WHAT THE HALF LIFE IS UNLESS YOU KNOW HOW MUCH YOU HAVE TAKEN. REFER TO HALF LIFE OF MEDICATION IF YOU KNOW THE DOSE TAKEN. HALF LIVES OF DRUGS DIFFER.
What do scientists call the time it takes for half of the radioactive atoms to change into daughter elements?
Scientists refer to the time it takes for half of the radioactive atoms to change into daughter elements as the half-life of the radioactive substance.
What does the half-life of a radioisotope refer to?
The length of time it takes for half of a radioactive sample to decay
What does half life mean with methadone?
It is simply the duration methadone remains active in your system. It does not necessarily refer to just the euphoric effects. AS you probably know, methadone has the longest half-life of all synthetic opiates.
How many years in two half lives?
Two half-lives refer to two complete cycles of decay in a substance, where each half-life is the time it takes for half of the original amount to decay. Thus, the total time for two half-lives is simply twice the duration of one half-life. For example, if one half-life is 5 years, then two half-lives would equal 10 years.
