Homework Help: Atomic Nucleus (first year college)

  1. Mar 6, 2016 #1
    1. If we have sixty atomic nucleus that decay under ten days. How can we figure out their half life, their activity and a function? This graph shows how they decay: http://imgur.com/OSUB2P4

    x axis illustrates times given in day, y axis illustrates number of atomic nucleus decay



    2. No equations given.


    3. I do not know where to start, perhaps by finding decay constant or their activity?

    Based on that data alone? Forget it. You would either need the total number of atoms, or a clearly reducing decay rate over time to fit an exponential to it.

    If it is experimental data, you also need the background rate.
