  1. Your question is unclear. Are you asking for the ionic radius of As vs that of Sb or for the ionic vadius of elements beginning with As and ending with Sb. And which ion (+3, +5, or some other) are you asking about. Here is a site that explains about covalent and ionic radii (the ionic radii is near the end but it will help to read all of it).
