Difference in Electronegativity

Postby Helen_Lee_1L » Wed Oct 19, 2016 12:46 pm

So I know that if the electronegativity difference > 2, then it's considered an ionic bond. And that if the electronegativity difference <1.5, then it's considered a covalent bond. What if the electronegativity difference is between the intervals of 1.5 and 2? How do you determine if the heteronuclear atoms are ionic or covalent?

Before between 2 and 1.5, one has to look specifically at the heteronuclear atoms. Case by case basis.

Is ionic character based on the difference in electronegativity? For example, does a greater ionic character mean a greater difference in electronegativity in a bond?

Yes Josue, the greater the difference in electronegativity, the greater the charge difference, and thus the greater ionic character of the covalent bond
