Here is a Chlorine atom!How many electrons are in the Outer Shell? : 

Here is a Chlorine atom!How many electrons are in the Outer Shell?

Here is a Sodium atom!How many electrons are in the Outer Shell? : 

Here is a Sodium atom!How many electrons are in the Outer Shell?

Slide 6: 

So what has to happen? Hey where are you going with that electron?

Slide 7: 

Hey I almost lost my head…

Now we are getting somewhere.. : 

Now we are getting somewhere..

Slide 9: 

So is Chlorine stable now?

Well how about Sodium? : 

Well how about Sodium?

Slide 11: 

So we have 2 ions… The charge on Chlorine is? The charge on Sodium is? This is a Ionic Bond!

Here is a Oxygen atom…it has how many electrons in the outer shell? : 

Here is a Oxygen atom…it has how many electrons in the outer shell?

…and here are 2 Hydrogen atoms, how many electrons are in their outer shell? : 

…and here are 2 Hydrogen atoms, how many electrons are in their outer shell?

What are you going to do? : 

What are you going to do?

Bulldozing Hydrogen atoms over to share electrons with the Oxygen atom. : 

Bulldozing Hydrogen atoms over to share electrons with the Oxygen atom.

So there is one bond… : 

So there is one bond…

Here comes the next bond… : 

Here comes the next bond…

So now we have H2O or a water molecule!We have 2 covalent bonds, which means the sharing of electrons. So all three atoms have full outer shells while sharing these electrons. : 

So now we have H2O or a water molecule!We have 2 covalent bonds, which means the sharing of electrons. So all three atoms have full outer shells while sharing these electrons.

Carbon atom with 4 outer electrons, it needs to find 4 more electrons to be stable. : 

Carbon atom with 4 outer electrons, it needs to find 4 more electrons to be stable.

Slide 20: 

This is CH4 or Methane gas!

Two Hydrogen molecules bonding together covalently, sharing electrons! This makes hydrogen gas or H2! : 

Two Hydrogen molecules bonding together covalently, sharing electrons! This makes hydrogen gas or H2!

Slide 22: 

Well that is all, remember… Ionic bonding is the transfer of electrons, and Covalent bonding is the sharing of electrons!
