The formula to calculate the Percent Ionic Character is:
\[ \% \text{ionic character} = 100 \left( 1 - \exp\left( -0.25 \left( X_A - X_B \right)^2 \right) \right) \]
Percent Ionic Character is a measure of a compound or molecule's ionic and covalent character. A higher magnitude of this value indicates that the bonding is more ionic in nature. The electronegativity of element A and element B are the values that represent the tendency of an atom to attract a bonding pair of electrons in the AB molecule.
Let's assume the following values:
Using the formula:
\[ \% \text{ionic character} = 100 \left( 1 - \exp\left( -0.25 \left( 1.2 - 3.2 \right)^2 \right) \right) \approx 63.2121 \]
The Percent Ionic Character is approximately 63.2121%.
| Electronegativity of Element A | Electronegativity of Element B | Percent Ionic Character (%) |
|---|---|---|
| 1.1 | 3.2 | 66.796005465533938 |
| 1.2 | 3.2 | 63.212055882855765 |
