Carbon-dating. This is a process by which the proportion of carbon-14 in an organism is compared to the proportion know to be in the environment the carbon came from. By comparing the proportions, a scientist can determine the amount of time since the last replacement of the carbon-14, and thus give a rough time of how long ago the organism died.

What percent of carbon14 is left after 5 half-lives?
3.125% would be left over.
What is lava used for?
Lava itself is not 'used', but solidified lava has many uses. Scoria can be used as decorative stone, and pumice can be used as an abrasive. Obsidian is used in jewelry.
What is Plate Tectonics used for?
used to create mountains. no, it is also used to make volcano's.
What is H2O2 used for?
H2O2 can used as Disinfectant.
What is bornite used for?
It is used to extract copper.
What happens to the amount of nitrogen14 as the carbon14 decays?
Remains the same
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?
Yes, but the dating is only off a little (500 years or so).
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 is the mass number of carbon14?
Carbon is a non metallic element. Mass number of it is 12.
What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
What percent of carbon14 is left after 5 half-lives?
3.125% would be left over.
How many protons neutrons and electrons are in carbon14?
7 protons, 7 neutrons and 7 electrons
Why are atomic masses written as averages?
elements exist in more than one form eg carbon 12 and carbon14
Does the carbon14 have more protons neutrons or electrons than carbon12?
It has the same number of protons and electrons, but two more neutrons.
What two things must scientist measure to find the absolute ages of rocks?
scientists use carbon14 and potassium argon to find absolute age of rock
Why is carbon14 dating not accurate for estimating the age of materials more than 50.000 years old?
Too little carbon-14 remains after 50,000 years
What two things must scientist measure to find the absolute age of a rock?
scientists use carbon14 and potassium argon to find absolute age of rock
