Answer :
Carbon-14 has a half-life of 5,730 years, So:
2 x 5,730 years = 11,460 years.
So it would take 11,460 years for three-quarters of the original amount of carbon-14 in the sample to become stable.
What do you mean by half-life?
The half-life of a radioactive isotope is the time it takes for half of the original amount of the isotope to become stable. Therefore, the time it takes for three-quarters of the original amount of the isotope to become stable is twice the half-life, since half-life is the time for half to decay.
What are two main properties of carbon?
Catenation which means self linking of carbon atoms to form long chains and Tetravalency are the two properties of carbon. This might lead to the formation of a large number of carbon compounds.
