Radioactive Decay

  1. Jun 12, 2009 #1
    The problem states:

    I know it's beta decay, but there are two types of beta decay and I'm not sure how to tell which one would happen. If anyone is more familiar with these kinds of questions than I am, I'd be really thankful for any help.

    Thanks ahead of time!

    First of all, which isotope is the stable one?

    Knowing that then, in which direction is the β decay?

    Proton to neutron β-

    or

    neutron to proton β+?

    Doesn't the transition tell you?

    I'm not quite sure what you mean by transition, but the question doesn't say anything about which atom is more stable.

    Is it possible to tell from the periodic table?

    By transition, I was meaning alchemy. One element to another.

    The half life is certainly something you can look up I would think.

    Without looking, I would intuitively think iron is a more stable element than cobalt. But you should check to be sure.
