3. Learning Target
I can differentiate between an ionic & a covalent bond.

4. Why do atoms form bonds?
To become stable.

5. What are the two types of chemical bonds we have been studying?
Ionic
Covalent

6. Ionic Bonds

7. Which types of elements will form ionic bonds with each other?
Typically, these types of bonds will form between metals and non-metals.
Why?
Metals will form cations (+ charge) while non-metals will form anions (- charge)
Example:
Potassium (K) metal forms a +1 cation, while Chlorine (Cl) non-metal forms a -1 anion.
These elements will form an ionic bond to form KCl.

8. How do ionic bonds form?
Electrons are transferred from one atom to another, which means that the atoms are no longer neutral.
The ionic bond forms due to the attractions between oppositely charged ions.

9. What do ionic bonds form?
These form network structures, because each ion will touch several others, forming a network.
Can ionic bonds conduct electricity? Why or why not?
When melted or dissolved in water, ionic substances conduct electricity, since the ions are no longer locked in place.

10. What do you know about covalent bonds?
These form when atoms share pairs of electrons.
These types of bonds form between non-metals.
Form solids, liquids, and gases
These types of substances typically have low melting points, and generally do not conduct electricity, because they are not charged.

11. Covalent Bonds

12. The more shared electrons, the greater the bond strength!
Sharing of electrons
Atoms can share one or more pairs of electrons.
One pair is a SINGLE COVALENT bond
Two shared electrons
Two pairs is a DOUBLE COVALENT bond
Four shared electrons
Three pairs is a TRIPLE COVALENT bond
Six shared electrons
The more shared electrons, the greater the bond strength!
