    you should handle iodine as safe as you can because it can burn the skin and damage the eyes. Pure iodine is poisonous if ingested.

    If you got it from Chernobyl, yes.

    That depends on the isotope.  I-127 is stable and not radioactive.

    to the other people answering this question... 

    .. "elemental" iodine means I2

    The vast majority of Iodine (127 I) is VERY stable, that is non-radioactive.

    Other isotopes (various neutron counts) are made synthetically and are radioactive with half-lives of 6 hours to billions of years

    Gets its name from the violet appearance, esp. in gas form.

    NO!!!

    However, there is an isotope of Iodine which is radio-active.

    The next element down the halogen group , Astatine, is radio active.

      there are an infinite # of isotopes of iodine that are radioactive, not just 1

    No, it is a gas that can combine with other elements, but not radioactive like uranium.

      what?  I2 is a gas?????  what does uranium have to do with this?

    Many of the isotopes of iodine are radioactive, but iodine 127 is 100% stable. "Elemental iodine" is confusing. All isotopes of elements are "elemental."

      "elemental" means "as the element is found in nature".  Iodine is found as I2.

    The iodine you find in nature is all I127 and it's stable.

     

    There are other isotopes from I120 through I135 but they are all man made.  Most have a short half lives (min to days) but I129 has a half life of 1.7 * 10^7 years.

      there are more isotopes than just I120 to I135.  Those are the "discovered" ones.  There are an infinite # of possible isotopes.  All but I127 are probably radioactive to some degree.

    Surprisingly

    there are no known naturally-occurring radioactive isotopes of iodine.

    The only known naturally-occurring isotope of Iodine is I-127

    which is NOT radioactive.
