Carbon-14 is a radioactive isotope of carbon. It decays into Nitrogen-14 through beta decay, with a
half-life of 5730 years. By comparing the amount of radioactive Carbon-14 with the amount of stable
Carbon-12 (the most common isotope of carbon), we can determine the age of an object.

a) How many protons and neutrons are in Carbon-14? Carbon-12?
b) How many years will it take for an object to lose 87.5% of its Carbon-14?
c) If 10000 years have passed, what percentage of Carbon-14 is remaining?

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...

The half-life of a radioactive isotope represents the average time it would take half of a collection of this type of nucleus to decay. For example, you start with a sample of 1000 Oxygen-15 (15O) nuclei, which has a half-life of 122 seconds. After 122 seconds, half of the 15O nuclei will have decayed into Nitrogen-15 (15N) nuclei. After another 122s, half of the remaining Oxygen nuclei will have also decayed, and so on. Suppose you start with 4.00×103 15O...

The 238U nucleus has a relatively complicated radioactive decay sequence until it becomes a stable 206Pb nucleus. The questions below should help you understand why this sequence is not a simple series of alpha decays, but involves both alpha and beta-minus decays. How many protons and how many neutrons must be removed from the unstable 238U nucleus to decay into a stable 206Pb nucleus? 1)How many protons and neutrons? 2) Find the minimum, actual, and extra number of alpha decays...

The radioactive isotope 14C is produced in the earth’s atmosphere by bombardment of nitrogen by cosmic rays. The 14C enters living organisms, where the ratio of 14C to 12C is the same as in the atmosphere, about . After 1.20×10―12an organism dies, the 14C decays with a half-life of 5730 years. The mass of a neutral 12C atom is 1.993kg.×10―26 (a) A tapestry is determined by mas spectroscopy to contain a ratio of 14C to 12C of . How old...

(A)This exercise uses the radioactive decay model. The burial cloth of an Egyptian mummy is estimated to contain 58% of the carbon-14 it contained originally. How long ago was the mummy buried? (The half-life of carbon-14 is 5730 years. Round your answer to the nearest ten years.) yr (b)This exercise uses the radioactive decay model. A wooden artifact from an ancient tomb contains 60% of the carbon-14 that is present in living trees. How long ago was the artifact made?...
