We picked up 3 handouts which should be found in the Handouts Folder

We graded and went over our quizzes in class

We continued the notes on Molecule Polarity:

Molecule Polarity:
1) Are the bonds polar?
2) Is the molecule symmetrical?
3) Is the molecule polar?

Ex: ClO3 with a negative 1 charge
      =26 valence electrons

Hybridization 
To be a blend of something

Different atomic orbitals (s,p,d,f) are mixed to form new identical orbitals

Ex: SP3 orbital                  } A blending of orbitals
      SP3D orbital                }

(Proposed by Linus Pauling, it solves a big bonding problem)

What's the problem?
-The valence electrons don't fill each properly

The shape of the orbitals (doing the bonding) should look like the shape of the molecule.
THEY DON'T.

Pauling suggested that when electrons bond they are going to form a hybrid orbital to form the shape that we expect.
