What words... super, excellent idea
Purpose: To explore Half-life of a Radioisotope. Introduction: In this lab you will investigate radiometric dating. The pennies represent the 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 it own characteristic half-life.
This decay of radioactive nuclei is a random event. Each radio nuclide has it own characteristic half-life. Half-lives range from nanoseconds to billions of years.
Materials: pennies, Graphical Analysis. Place these pennies into a container.
7.16 radioactive dating lab questions
Dump the pennies. The pennies that landed heads-up will represent decayed nuclei, the pennies tails-up are your remaining sample. Count and the number of pennies that decayed and count the remaining pennies in the sample, and place the data in the appropriate column.
Repeat step 2 until all of the pennies have decayed. Each time you dumped the pennies, one half-life passed; it has been shown that the half-life for this radioactive isotope is 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.
