Florida College. Applied Ethics PHI Introduction: In this lab, you will investigate radiometric dating. The pennies represent 7.16 radioactive dating lab radio nuclide contained in our sample. An unstable nucleus decays in order to achieve a new nucleus that is either stable or a new nucleus that, in turn, will decay. This half-life is intrinsic to the isotope and cannot be altered by any extrinsic parameters such as temperature, pressure, or light.
This decay of radioactive nuclei is a random event. Each radio nuclide has its own characteristic half-life. Half-lives range from nanoseconds to billions of years. Materials: pennies, Graphical Analysis. Gone through 3 half lives 2. Each time you dumped the pennies, one half-life passed; it has been shown that the half-life for this radioactive isotope 7.16 radioactive dating lab 20 years. In the yearan archaeology team unearths pottery and is using this isotope for radiometric dating to place the age of the pottery. Using your graph, approximately how long ago was the pottery made?
While investigating the half-life of a radioactive isotope, the following data was gathered. Graph the data; this graph should resemble the graph from your lab. This is called a decay curve. Answer the following questions:. Comments Please in or register to post comments. Students also viewed 7.
