according to my research the bromine ion should be smaller than the iodine from the chart i found (see link below)

seems to indicate that atomic radius is smallest in the upper right hand corner of the periodic chart and largest in the lower left hand corner. Since Br is directly above I it should have a smaller radius. There might be rules i am not aware of but this is my best guess.

Thanks=)

i am a work in progress but i pay close attention to everything. I feel it is a good thing to share the knowledge i have acquired in my travels to anyone asking and it brings me pleasure to do so. i have lived in California, Alaska, Idaho, and New Mexico and been married and divorced. I have no children of my own but have fostered several .
