BONDING AND ELECTRONEGATIVITY

Electronegativity is an atom's pull on the electrons within a bond.  Higher electronegativity  indicates a stronger pull on the electrons.  Remember negative electrons are attracted to positive protons in the nucleus due to electrical force (opposite charges attract). 

The difference in electronegavity (subtract larger - smaller) between two different atoms can be used to predict the polarity of the bond between the atoms.

A difference of less than 0.5 can be classified as a ___________.

A difference between 0.5 and 1.9 can be classified as a ___________.

A difference greater than 1.9 can be classified as a ___________.
