Electronegativity measures atom's ability to attract electrons in bond; higher EN = stronger attraction, more polar bond.
Guia passo a passo
- 1Input element pair
- 2Look up electronegativity values (Pauling scale)
- 3Calculate electronegativity difference
Exemplos resolvidos
Entrada
H-F: EN difference 1.9 (polar covalent)
Resultado
Na-Cl: EN difference 2.1 (ionic character)
Erros comuns a evitar
- ✕Assuming EN determines exact reactivity
- ✕Not accounting for other factors (size, charge)
Perguntas frequentes
How does EN relate to polarity?
ΔEN < 0.5: nonpolar, 0.5-1.7: polar, > 1.7: ionic character.
