Electronegativity increases towards the __________ and __________.
Electronegativity is ________________________.
Right and Top.
An Atom’s ability to attract bonding electrons.
Non polar covalent:
Polar covalent:
Ionic:
Equal sharing.
Unequal sharing.
Little or no sharing.
What’s the dipole moment?
Write down the equation for the dipole moment.
What’s equivalent to 1 unit of it?
Is the measure of polarity of a chemical bond. It relates charge and bond length.
1 Debye: 3.34x10^-34 C•m
Which elements tend to follow the octet rule?
First, most S and P block elements.
Second, second and third period elements (14-13 to 17 group).
Formal charge is ______ and is represented by the equation ______.
The charge each atom would have if electrons were shared equally.
FC= #Valence - #0.5Bonding - #NonBonding
What are the exceptions to the Octet rule?
Odd # of electrons.
Incomplete Octets.
Expanded Octets.
What’s the Effective nuclear charge?
What effect does that have on the Atomic Radii and how does that relate to Ionic Radii?
Is the positive charge experienced by an electron in an atom.
The more positive charge, the smaller the Atomic Radii.
The Cation is smaller because it is more positive. (Mg2+)

Always non-polar .
Molecular Orbital Diagrams only apply to…
Homonuclear Diatomic Molecules
How to calculate Bond Order?
Bond Order = 1/2(#Bonding e- #Antibonding e)
