Answer: 75 grams If you had a 5-gram sample of Lawrencium, how much would still remain after 30 minutes?
Answer: none If you had a 100-gram sample of Einsteinium, how much would remain after 40 days?
Radiometric Dating and the Geologic Time Scale, The Talk Origins Archive. Provides brief overview of (1) relative dating and stratigraphic methods, (2) absolute dating and radiometric dating, including a table with parent to daughter isotopes and half lives of those isotopes commonly used in radiometric dating, (3) paleomagnetics and (4) geologic time. Includes tables of common radioactive parent isotopes and their stable daughter products, and half lives of common radioactive isotopes.
This group is dedicated to providing information about the scientific method as it concerns the idea of evolution in the Creation/Evolution debate.
Half of these carbon-14 atoms will decay during the next 5730 years; therefore after three half-lives, one-eighth of the original carbon-14 atoms still remains.
Carbon-14 is useful for dating fossils up to 50,000 years old.The half-life of an isotope is the time it takes for half of the atoms in the isotope to decay.The half-life of carbon-14 is 5730 years; therefore, it will take 5730 years for half of the carbon-14 atoms to decay to nitrogen-14.What is the total amount of time represented by the cuts?Use the following table of some other isotopes and their half-lives to answer the questions listed below: INSERT TABLE HERE If you had a 100-gram sample of plutonium, how much would remain after 43 years?
