There was 62.23% change in radius as the ion formed.

Step-by-step explanation:

Given

Radius of Aluminium (Al) atom = 143 pm

Radius of Aluminium $(Al^{3+})$ atom = 54 pm

Change is the radius = Radius of Aluminium (Al) atom - Radius of Aluminium $(Al^{3+})$ atom = 143 -54 = 89

Now to find % Change is the radius we will divide Change is the radius by Radius of Aluminium (Al) atom and multiply by 100 we get

% Change is the radius = $\frac{\textrm{Change is the radius}}{\textrm{Radius of Aluminium (Al) atom}} \times 100 = \frac{89}{143}\times100= 62.23\%$

Hence there was 62.23% change in radius as the ion formed.
