Unit 08 Bonding Concepts
8.2 Electronegativity
Read and outline 8.2
Define
Electronegativity
8.2 Notes
Electronegativity is the ability of an atom to attract shared electrons to itself.
Expected H-X bond energy = H-H bond energy + X-X bond energy
2
∆ = (H-X) act – (H-X)exp
When the bond strength is greater the actual bond energy will be larger than the expected.
Example
Order the following bonds according to polarity: H-H, O-H, Cl- H, S-H, and F-H.
