Chemical reactivity simple question

[hiuting]

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.
