PRESENTATION OUTLINE
1.
Chapter 12: bonding
Megan balter and hannah tulchinsky
2.
Covalent vs Ionic Bonding
the similarities and differeces
3.
Chemical Bond
Bond between two or more elements
It is formed when either electrons are shared
Energy is stored within all chemical bonds
4.
Covalent Bonds
bond formed between two non-metals
atoms share valence electrons
the sharing is polar or non-polar
5.
Covalent Bond Polarity
6.
Polar Covalent
the unequal sharing of valence electrons
results in relatively charged molecules
7.
Non-polar covalent
the equal sharing of valence electrons
no relative charge
8.
Ionic Bonds
formed between a metal and non-metal element
valence electrons are transferred, not shared
atoms become ions
cation: the positively charged atom
anion: negatively charged atom
9.
Covalent and Ionic Bond similarities
involve valence electrons
bonds between two or more elements
result in either relative charge or certain charge
10.
Covalent and ionic bond differences
covalent involves two non-metals
ionic involves a non-metal and metal
ionic bonds transfer electrons
covalent bonds share electrons
11.
Covalent and ionic bond differences
covalent involves two non-metals
ionic involves a non-metal and metal
ionic bonds transfer electrons
covalent bonds share electrons
12.
Electrostatic Attraction
-the attraction between positive and negative ions that makes them bond
13.
What is Electronegativity
The relative ability of an atom to attract shared electrons
The range values from 4.0 to o.7
The more similar the atoms are, the less polarity there is
The less similar the atoms are, the more polarity there is
14.
Polarity
Depends on the difference between the electronegativity values of the atom
Atoms with similar electronegativities= little polarity
atoms with greater electronegativity=greater polarity
15.
Determining Polarity
Greater number of electronegativity - less number of electronegativity
Use the polarity scale to see if it's non polar covalent, nonpolar covalent
Or ionic
16.
Determining the type of bond
0.0 -> 0.4 = non polar covalent
0.4 -> 2.0 = Polar Covalent
2.0 -> 4.0 = Ionic
17.

Dipole Moment
A molecule that is polar and has a negative pole
Any diatomic (two-atom) molecule that has a polar bond has a dipole moment.
Least amount of electronegativity are pulled to electrons with the most
19.

20.
Lewis Dot Diagrams
Show only the valence electrons and the chemical symbol of the element
When a bond is formed, dots are replaced with dashes
The remaining dots show the un-bonded electron pairs
21.
Types of bonds
Single Bond: Sharing one pair of electrons
Double Bond: Sharing two pairs of electrons
Triple Bond: Sharing three pairs of electrons
22.
Resonance Structures
When there is more than one possible lewis structure
23.
