Q1. Carbon-14 – or 14C – is a radioactive isotope of carbon with a half-life of 5,730 years. It decays into nitrogen-14 – or 14N – , which is a stable isotope of nitrogen. (a) Which of the three nuclear decay processes describes the decay? Explain. (Hint: You can get the atomic number of carbon and nitrogen from a periodic table.) (b) Write down the equation for the decay. (c) What is the decay constant for 14C? All isotopes of...

Carbon 14 is a radioactive isotope of carbon, the most common isotope of carbon being carbon 12. Carbon 14 is created when cosmic ray bombardment changes nitrogen 14 to carbon 14 in the upper atmosphere. The resulting carbon 14 combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis. Animals acquire carbon 14 by eating plants. When an animal or plant dies, it ceases to take on carbon 14, and the amount of isotope...

remains of ancient human bones have been found. The carbon 14 present on these bones represented only 2.6% of the carbon 14 present in nature. The missing 97.4% had disintegrated. Estimate the age of these anthropological remains by considering that the half-life of carbon-14 is 5730 years.
