The radius ratio is a measure used to compare the size of a cation to the size of an anion. It is calculated by dividing the radius of the cation by the radius of the anion. This ratio is important in determining the stability and structure of ionic compounds.
The formula to calculate the radius ratio is:
\[ RR = \frac{Rc}{Ra} \]
Where:
Let's assume the following values:
Using the formula:
\[ RR = \frac{0.5}{1.0} = 0.5 \]
The radius ratio is 0.5.
