Electronegativity is a measure of an atom's ability to attract electrons in a bond, with values determined by Linus Pauling allowing placement on a numerical scale. Electronegativity values can be used to determine if a bond is nonpolar covalent with equal electron sharing, polar covalent with unequal sharing, or ionic with complete electron transfer between atoms.

1. Electronegativity
and
Bonding

2. Electronegativity
- is a measure of the
tendecy of an atom to
attract a bonding pair of
electrons.

3. The modern definition of
electronegativity is due to linus
pauling.
The power of an atom to develop
a numerical scale of
electronegativities.

5. Electronegativity values are useful in
determining if a bond is to be
classified as nonpolar covalent or
ionic.
1.Nonpolar Covalent: This type of
bond occurs when there is equal
sharing (between the two atoms) of
the electrons in the bond.

6. 2.Polar Covalent: This type of bond
occurs when there is unequal sharing
(between the two atoms)of the
electrons in the bond.
3.Ionic: This type of bond occurs when
there is complete transfer (between
the two atoms) of the electrons in the
bond.
