3. HONC1234
We can summarizing the bonding of the 4 main organic elements using the following rule
Hydrogen forms 1 bond
Oxygen forms 2 bonds
Nitrogen forms 3 bonds
Carbon forms 4 bonds
With your table, form a hypothesis as to why you think these elements form the bonds that they do

4. The Octet Rule REMEMBER
Noble gases have 8 valence electrons (a full octet) and are very stable
In order to be stable, all elements want to gain, lose, or share electrons to have a full octet

5. The Octet Rule REMEMBER
Noble gases have 8 valence electrons (a full octet) and are very stable
In order to be stable, all elements want to gain, lose, or share electrons to have a full octet
How many valence electrons does carbon have? How many does it have room for?

6. The Octet Rule REMEMBER
Noble gases have 8 valence electrons (a full octet) and are very stable
In order to be stable, all elements want to gain, lose, or share electrons to have a full octet
How many valence electrons does nitrogen have? How many does it have room for?

7. The Octet Rule REMEMBER
Noble gases have 8 valence electrons (a full octet) and are very stable
In order to be stable, all elements want to gain, lose, or share electrons to have a full octet
How many valence electrons does oxygen have? How many does it have room for?

8. The Octet Rule REMEMBER
Noble gases have 8 valence electrons (a full octet) and are very stable
In order to be stable, all elements want to gain, lose, or share electrons to have a full octet
How many valence electrons does hydrogen have? How many does it have room for?

10. Multiple Bonds
Molecules can contain double or triple bonds so that two atoms can share more than two electrons
A double bond contains 4 electrons
A triple bond contains 6 electrons
