Read each question carefully and provide clear, concise answers. Show all your work for drawing Lewis Dot Structures.
1. Lewis Dot Structures use dots to represent electrons.
2. The rule states that atoms tend to gain, lose, or share electrons in order to achieve a full outer shell of eight electrons.
3. In a Lewis Dot Structure, a single line represents a bond, which consists of two shared electrons.
4. How many valence electrons does a Nitrogen atom (N) have?
3
5
7
8
5. Which element is an exception to the octet rule and can have fewer than eight electrons in its valence shell when bonded?
Carbon
Oxygen
Boron
Fluorine
Draw the Lewis Dot Structure for the following molecules or ions. Show all lone pairs and formal charges where applicable.
6. H₂O (Water)
7. CO₂ (Carbon Dioxide)
8. NH₃ (Ammonia)
9. CN⁻ (Cyanide ion)
10. All atoms in a stable Lewis Dot Structure must satisfy the octet rule.
True
False
11. Lone pairs of electrons are shown as dots on the central atom only.
True
False
