How to Calculate Electronegativity
What is Electronegativity?
Electronegativity measures atom's ability to attract electrons in bond; higher EN = stronger attraction, more polar bond.
Step-by-Step Guide
- 1Input element pair
- 2Look up electronegativity values (Pauling scale)
- 3Calculate electronegativity difference
Worked Examples
Input
H-F: EN difference 1.9 (polar covalent)
Result
Na-Cl: EN difference 2.1 (ionic character)
Common Mistakes to Avoid
- ✕Assuming EN determines exact reactivity
- ✕Not accounting for other factors (size, charge)
Frequently Asked Questions
How does EN relate to polarity?
ΔEN < 0.5: nonpolar, 0.5-1.7: polar, > 1.7: ionic character.
