Part A How long does it take for the radioactive isotope to decay to 6.0×10−4 μg ? (Assume no excretion of the nuclide from the body.) Part B A radioactive sample contains 1.70 g of an isotope with a half-life of 3.6 days. What mass of the isotope will remain after 5.8 days? (Assume no excretion of the nuclide from the body.) Part C A mammoth skeleton has a carbon-14 decay rate of 0.46 disintegrations per minute per gram of...

Which type of nuclear decay is the following radioactive isotope likely to undergo? All known stable isotopes are shown on the graph. The points form what is know as the "belt of stability". If a radioactive isotope is above the belt of stability, think about what type of decay would decrease its N/Z ratio. If an unstable isotope is below the belt of stability, think about what type of decay would increase its N/Z ratio. If a radioactive isotope is...

The radioactive decay of radium 226Ra follows a first-order rate law. This decay process has a half-life of 1600 years. (a). What is the value of the rate constant (expressed in s-1) for this decay process? (b). How many disintegrations per second would occur in a one-gram sample of 226Ra ?

We will be exploring decay reactions used in radioactive dating of objects. This will be a short lab to leave you time to prepare for the Unit 3 project. 1. Explore the PhET simulation Radioactive Dating Game . Try all the tabs to figure out why there is more than one element used to estimate how old things might be. 2. What elements’ isotopes are used to estimate how old something is? Why do are more than one type used?...

Radioactive decay can be used to determine the age of an object. If you know the number of radioactive nuclei with which an object started, the number of radioactive nuclei currently present, and the half-life of the isotope, you can calculate the time since the object was created. Suppose an object was created with 4.810×109 nuclei of a particular isotope that has a half-life of 1.56×103 yr. At this point in time 9.620×108 nuclei of this particular isotope remain. What...

Radioactive Isotope #1: Uranium-238 How long is its half-life? How long will it take the original radioactive product to reduce by 50%? How long will it take the original radioactive product to reduce by 25%? What material is the best application for this isotope? Describe the disadvantages and advantages of using this element for dating. What is the stable daughter product?
