1) The half-life of carbon 14 is 5600 years. Compute the rate of decay (constant ?) for this radioactive isotope (5 marks)
2) Traces of burnt wood along with ancient stone tools in an archaeological dig in Spain were found to contain approximately 10% of the original amount of carbon 14. Using the value of the constant ? from part 1), calculate when the tree was felled and burned.

Carbon-14 is a radioactive nucleus with a half-life of 5760 years. Living matter exchanges carbon with its surrounding so that a constant level of 14C is maintained, corresponding to 15.3 decay events per minute. Once living matter has died, carbon contained in the matter is not exchanged with the surroundings, and the amount of 14C that remains in the dead material decreases with time due to radioactive decay. Consider a piece of fossilized wood that demonstrates 2.4 14C decay events...

Be sure to answer all parts. The carbon-14 decay rate of a sample obtained from a young tree is 0.264 disintegration per second per gram of the sample. Another wood sample prepared from an object recovered at an archaeological excavation gives a decay rate of 0.193 disintegration per second per gram of the sample. What is the age of the object? (The half-life of carbon-14 is 5715 years.) × 1 ol 1 years Enter your answer in scientific notation.

1. The half-life of carbon-14 is 5730 years. A sample is found to have one-eighth the original amount of carbon-14 in it. How old is the sample? 5730 years, 716 years, 45800 years, 17200 years 2. Why wouldn't you use carbon-14 dating on a piece of shell that was estimated to be 1 million years old? Sea shells do not have radioisotopes, carbon dating is only useful on plants, uranium dating is better for items older than 1/2 million years,...
