It looks like you've uploaded an image of a
Covalent Bonding Worksheet with several problems involving Lewis structures, bond types (single, double, triple), and molecular formulas. However, I currently can't view or process images directly.
To help you effectively, please
describe the specific problem or question from the worksheet that you'd like me to solve. For example:
- Are you having trouble drawing Lewis structures?
- Do you need help identifying bond types (single, double, triple)?
- Are you confused about how to count valence electrons or determine formal charges?
Alternatively, you can
copy and paste the text of the questions from the worksheet here, and I’ll walk you through each step of solving them with clear explanations.
For now, I’ll give you a general guide on how to approach these types of covalent bonding problems:

🔍 General Steps for Solving Covalent Bonding Problems
1.
Identify the elements involved and their valence electrons.
- Use the periodic table:
- Group 1: 1 valence e⁻
- Group 2: 2 valence e⁻
- Group 13: 3 valence e⁻
- Group 14: 4 valence e⁻
- Group 15: 5 valence e⁻
- Group 16: 6 valence e⁻
- Group 17: 7 valence e⁻
- Group 18: 8 valence e⁻ (except He = 2)
2.
Add up total valence electrons in the molecule.
3.
Draw a skeleton structure:
- The least electronegative atom is usually the central atom (except H, which goes on the outside).
4.
Place bonds (lines) between atoms — each bond = 2 electrons.
5.
Distribute remaining electrons as lone pairs to satisfy the octet rule (duet for H).
6.
Check if all atoms have full octets (or duets for H). If not, form double or triple bonds by moving lone pairs into bonding positions.
7.
Label bond types:
- Single bond: one line (2 electrons)
- Double bond: two lines (4 electrons)
- Triple bond: three lines (6 electrons)

✔ Example Problem (from your worksheet):
Let’s say one question is:
"Draw the Lewis structure for O₂ and identify the bond type."
#### Step-by-step solution:
1. Oxygen (O) has 6 valence electrons → O₂ has 12 total valence electrons.
2. Two oxygen atoms bonded together.
3. Each O needs 8 electrons. Start with a single bond (2 electrons), then add lone pairs.
4. After single bond, each O has 6 more electrons (3 lone pairs).
5. But each O only has 7 electrons total (1 bond + 6 lone pair electrons).
6. So, we need a
double bond → 4 electrons shared.
7. Now each O has 8 electrons (4 from double bond + 4 from lone pairs).
8. Final structure: O=O with two lone pairs on each O.
9. Bond type:
Double bond.
