Answer:
There was 62.23% change in radius as the ion formed.
Step-by-step explanation:
Given
Radius of Aluminium
atom = 143 pm
Radius of Aluminium
atom = 54 pm
Change is the radius = Radius of Aluminium
atom - Radius of Aluminium
atom = 143 -54 = 89
Now to find % Change is the radius we will divide Change is the radius by Radius of Aluminium
atom and multiply by 100 we get
% Change is the radius = 
Hence there was 62.23% change in radius as the ion formed.
