Study Notes
Bond Type and Electronegativity
- The presence of a bond between two elements can be determined by calculating the electronegativity value between two atoms.
- A polar covalent bond has an electronegativity value between 0.5 and 1.9.
- A non-polar covalent bond has an electronegativity value between 0 and 0.4.
- An ionic bond has an electronegativity value between 2.4 and 4.0.
Properties of Covalent Compounds
- Covalent compounds have low melting and boiling points.
- Large differences in electronegativity between bonded atoms increase the polarity of the bond.
- More electronegative atoms have a stronger pull for electrons.
- The electronegativity difference (∆EN) between atoms in a covalent bond is greater than zero and less than 1.8.
