Chemical reactivity simple question

  1. Oct 31, 2009 #1
    1. The problem statement, all variables and given/known data
    Why does the chemical reactivity increase as we go down in a group?


    2. Relevant equations
    none


    3. The attempt at a solution
    I know it has to do with the atomic radius... but i'm not sure :P

    Because as you go down a group, electrons are held less tightly (less shielding), and since reactions result from the transfer of electrons, reactivity will increase.

    thanks :) I can't believe I didn't think of that.

    That's especially true if you compare iodine with fluorine.

    If you have not realized - this comment is intended to be sarcastic.
