Blank Periodic Table | Worksheet - Free Printable

To solve the problem, we need to follow these steps:

Step 1: Understand the Task

The task involves:
1. Identifying the element groups in the periodic table based on the key provided.
2. Writing the element symbols in the appropriate boxes of the periodic table.

Step 2: Analyze the Key

The key provides symbols or icons that represent different groups of elements in the periodic table. Each icon corresponds to a specific group (e.g., alkali metals, alkaline earth metals, transition metals, etc.). We need to match these icons with their respective groups and then fill in the corresponding element symbols.

Step 3: Recall the Periodic Table Structure

The periodic table is organized into several groups (columns) and periods (rows). The main groups are:
- Alkali Metals (Group 1)
- Alkaline Earth Metals (Group 2)
- Transition Metals (Groups 3–12)
- Post-transition Metals (some elements in Groups 13–15)
- Metalloids (elements near the staircase line)
- Nonmetals (Groups 14–18)
- Noble Gases (Group 18)

Step 4: Match Icons to Element Groups

Using the key provided in the image, match each icon to its corresponding group. For example:
- A particular icon might represent alkali metals.
- Another icon might represent noble gases.
- And so on.

Step 5: Fill in the Periodic Table

Once you have matched the icons to their groups, fill in the periodic table with the appropriate element symbols for each group. Here’s a general outline of where elements belong:
- Top left: Hydrogen (H), Alkali Metals (Li, Na, K, Rb, Cs, Fr)
- Second column: Alkaline Earth Metals (Be, Mg, Ca, Sr, Ba, Ra)
- Rightmost column: Noble Gases (He, Ne, Ar, Kr, Xe, Rn)
- Middle sections: Transition metals, post-transition metals, metalloids, and nonmetals.

Step 6: Write the Solution

After filling in the periodic table, write down the completed table with all the element symbols in their correct positions.

Example Solution (Hypothetical Based on Typical Periodic Table):

Assuming the key matches typical groups, here’s how the periodic table might look:

| | Group 1 | Group 2 | ... | Group 18 |
|---|---------|---------|-----|----------|
| 1 | H | He | | |
| 2 | Li | Be | | Ne |
| 3 | Na | Mg | | Ar |
| 4 | K | Ca | | Kr |
| 5 | Rb | Sr | | Xe |
| 6 | Cs | Ba | | Rn |

Final Answer:

Since the exact key is not provided in the question, I cannot give a precise answer. However, the process involves:
1. Matching icons to element groups using the key.
2. Filling in the periodic table with the correct element symbols.

If you provide the key or more details, I can refine the solution further!
