Arranging atoms/ions based on atomic radius
Hey, I'm in a bit of a bind here. I got a question that deals with atomic radius. The question asks to arrange the following atoms/ions in order from smallest to biggest:
[tex]Cl, S^{2-}, K, K^{+}, O[/tex]
I know just by looking at the periodic table that O has the smallest radius and that K has the largest radius... I also know that since [tex]S^{2-}[/tex] is larger than S and since S is larger than Cl that means [tex]S^{2-}[/tex] is also larger than Cl.
[tex]K^{+}[/tex] is smaller than K and larger than Cl since it has a greater energy level.
Here's my problem... I know that both [tex]K^{+}[/tex] and [tex]S^{2-}[/tex] fall somewhere between the Cl and K atoms... and by looking up the actual radius of the [tex]K^{+}[/tex] and [tex]S^{2-}[/tex] ions I know that the [tex]S^{2-}[/tex] radius is larger than the [tex]K^{+}[/tex] radius but how do i prove this?
Any help would be greatly appreaciated. Thanks!
