Electronegativity Difference and Bond Type

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

What is the electronegativity difference?

Back

The electronegativity difference is the absolute value of the difference in electronegativity between two bonded atoms.

Front

What is the significance of electronegativity difference in determining bond type?

Back

The electronegativity difference helps to classify bonds as ionic, polar covalent, or non-polar covalent.
