Lewis Dot Structures - Free Printable

Let's solve this step-by-step. The task is to fill in the table with information about each element and match each element to its correct Lewis Dot Structure (valence electrons shown as dots) on the right side.

🔍 Step 1: Understand the Columns

We need to fill in:

1. Period Number: The row number on the periodic table.
2. Number of Energy Levels: Same as the period number (each period corresponds to a principal energy level).
3. Group/Family Number: The column number (usually 1–18, but here it’s labeled as "Family").
4. # of Valence Electrons: The number of electrons in the outermost shell (often equal to the group number for main-group elements).
5. Draw a line to the correct Lewis Dot Diagram: Match the element to the correct dot diagram on the right.

🔗 Matching Lines (to the Right Side)

On the right, you have:
- Family 1: 1 dot → H, Na
- Family 2: 2 dots → Ca
- Family 3: 3 dots → Al
- Family 4: 4 dots → Si
- Family 5: 5 dots → None listed (but not needed)
- Family 6: 6 dots → O
- Family 7: 7 dots → Cl, Br
- Family 8: 8 dots → Ne

So draw lines:
- H → Family 1
- Ca → Family 2
- Al → Family 3
- Si → Family 4
- O → Family 6
- Cl → Family 7
- Ne → Family 8
- Na → Family 1
- Br → Family 7
