The radius of the aluminum atom is 143pm. the radius of the aluminum atom is 54pm. by what percentage did the radius change as the ion formed?

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.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
