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.
let L be <span>Lissette's age
and F </span><span>Francesca age
2 F - 3 = 13
2F= 16
F = 16/2 =8
