Electronegativity

I. Video on Electronegativity

Electronegativity is the relative ability of an atom in a molecule to attract a shared electron to itself

Bond polarity is determined by the difference between the two elements electronegativity values.

1. H-S or H-F 5. H-P or H-C

2. O-S or O-F 6. O-F or O-I

3. N-S or N-Cl 7. N-O or S-O

4. C-S or C-Cl 8. N-H or Si-H
