For each of the following pairs of atoms or ions, indicate which has the larger radius by entering < or > As As3- As As3+ As3+ As5+ As3- As3+

Step 1
Atomic radius is the distance from the center of the nucleus to the outermost shell of electrons. When an atom gains electrons, it becomes an anion (negatively charged ion) and its radius increases due to increased electron-electron repulsion in the outer shell. Show more…
