Carbon has the smaller radius. This is because it has less energy levels than Chlorine.
Mg2+ has the smaller radius. It has less energy levels than Fe2+.
Fluorine has the smaller radius for the same reasons as the other ones.
Ca2+ has the smaller radius. It has less energy levels, and it has more protons per electron, so they pull in more on the electrons.
