The formula to calculate the electronegativity difference is:
\[ \text{ED} = |\text{Xa} - \text{Xb}| \]
Where:
Let's consider an example:
Using the formula to calculate the electronegativity difference:
\[ \text{ED} = |3.0 - 2.1| = 0.9 \]
This demonstrates that with electronegativities of 3.0 and 2.1, the electronegativity difference is 0.9. ✅
