When an atom becomes a positive ion, the radius of the atom
(1) decreases
(2) increases
(3) remains the same

When an atom becomes a positive ion it pulls it's electrons closer, decreasing it's radius moreover, when it becomes a negative ion, it pulls it's electrons closer and decreases the radius

I hope this helps :)
