How would you determine the relative atomic sizes of a neutral atom and an ion?

I can't figure this out. It can't be that all neutral atoms are always smaller than all ions can it?

**For example, how would I determine if Cl- is smaller or larger than S?**.

(The answer is that Cl- is larger than S).

Is there a rule that applies to all comparisons of neutral atoms and ions?

For example, how would I determine if Na is smaller or larger than Cl-?

Thank you very much!
