What are we going to learn about???
Coordinate
Covalent

3. See if you can define the following words before starting the lesson…
• Anion- negative ion
• Cation-positive ion
• Octet Rule- rule that states that atoms tend to gain, lose,
or share electrons so that each atom has full outermost
energy level which is typically 8 electrons.
• Polyatomic Ion- charged group of covalently bound
atoms
• Monatomic Ion- ion formed from a single atom
• Molecule-neutral group of atoms united by covalent
bonds
• Alloy- homogeneous mixture of metals
• Unshared Pair- pair of electrons that is not involved in
bonding but instead is held exclusively by one atom.

4. Marriage
Forming
of a bond
is like
marriage
•More stable
•exothermic
Divorce
•Less stable
•Endothermic
The
breaking
of a bond
relates to a
divorce.

5. Ionic Bonds
•What is an Ionic Bond?
- An Ionic Bond is a chemical bond
resulting from the TRANSFER of electrons
from one bonding atom to another
• When is an ionic bond formed?
- An ionic bond is formed when a cation
(positive ion) transfers electrons to an
anion (negative ion).

6. What are some characteristics of an ionic
bond?
1.
2.
3.
4.
Crystalline at room
temperatures
Have higher melting
points and boiling points
compared to covalent
compounds
Conduct electrical
current in molten or
solution state but not in
the solid state
Polar bonds

7. Covalent Bonds
•What is an Covalent Bond?
- A covalent bond is a chemical bond
resulting from SHARING of electrons
between 2 bonding atoms.
• What forms a covalent bond?
- A covalent bond is formed between two
nonmetals.

8. What are some characteristics of a covalent
bond?
1.
2.
3.
Covalent bonds have
definite and predicable
shapes.
Very strong
Low melting and boiling
points

9. Covalent Bonds can have multiple bonds, so you should be
familiar with the following…
Single Covalent Bondchemical bond resulting
from sharing of an electron
pair between two atoms.
Double Covalent Bondchemical bond resulting
from sharing of two electron
pairs between two atoms.
Triple Covalent Bondchemical bond resulting
from sharing of three
electron pairs between two
atoms.

10. There are five different categories associated with covalent
bonds. What are the 5 different categories?
Covalent
Molecular
Substance
Network
Solids
Polar
Nonpolar
Coordinate
Covalent

11. First, we are going to look at Polar Covalent…
What is polar covalent?
-Polar covalent is a description of a
c
bond that has an uneven distribution
of charge due to an unequal sharing of
bonding electrons.
The boy is not equally
sharing with anyone
else but rather taking
all the food for himself.

12. Next, we are going to look at Non-Polar Covalent…
What is non-polar covalent?
-Non polar covalent is a covalent
bond that has an even distribution of
charge due to an equal sharing of
bonding electrons.
This couple is
non- polar
because they are
sharing the drink
equally between
them.

13. Next, we are going to look at Molecular Substances…
What is a molecular substance?
-A molecular substance is a substance
that has atoms held together by
covalent bonds.
Name 2 Characteristics of a
Molecular Substance.
1. Weak
2. Low melting and boiling
points

14. Next, we are going to look at Coordinate Covalent…
What is a Coordinate Covalent Bond?
-A coordinate covalent bond is a
bond formed when one atom donates
both electrons that are shared.
People donate their
blood to help others
just like atoms
“donate” electrons to
form stable octets.
*Think about the party analogy!

15. Now, we are going to look at Network Solids…
What is a Network Solid?
-A network solid is a solid that has
covalently bonded atoms linked in
one big network or one big
macromolecule.
Name 3 Characteristics of a
Network Solid.
1. Poor conductors of heat
and electricity
2. Hard / Strong
3. High melting and boiling
points
Diphenylglycoluril
assembles into a unique, twodimensional hydrogen
bonding network in the solid
state, while exhibiting a
twisted molecular structure.

16. Metallic Bonding
What is a Metallic Bond?
- A metallic bond occurs in
metals. A metal consists of
positive ions surrounded by a
“sea” of mobile electrons.
This
shows
what a
metallic
bond
might
look
like.
Name 4 Characteristics of a
Metallic Bond.
1. Good conductors of heat
and electricity
2. Great strength
3. Malleable and Ductile
4. Luster

17. Polyatomic Bonds
Polyatomic ions usually have a
charge because the collection of
atoms has either gained an extra
electron or else it has lost an
electron.
What is a Polyatomic Bond?
- A polyatomic bond is
charged group of covalently
bonded atoms. It is made up
of more than one atom.

18. Linear
Trigonal Planer
Trigonal Bipyramidal
Tetrahedral
Octahedral

19. Just as a summary to what each
bond looks like…
