Hi everybody,

I have a question, which seems simple but honestly I am trap with.

I have 2 atoms, Ti and Zr and their ionic radii:
Ti= 60.5pm and Zr=72pm
If I want to report the ionic radii ratio, I could say that Ti radius is 15.97% smaller than Zr or Zr radius is 19% bigger than Ti.
Is this correct?
Is there any other way that I can say something about their radii ratio by a only unique number?
It is somehow frustrating for me that I have to use different number when I make their radii ratio.

Thanks for your time and help,

For me radii ratios are:

r(Ti)/r(Zr) = 60.5/72 = 0.84
or
r(Zr)/r(Ti) = 72/60.5 = 1.19
In other words:

Ti radius is 16% smaller than Zr
or
Zr radius is 19% bigger than Ti.
