Periodic Table of Elements Worksheet for educational use.

It looks like you've uploaded a Periodic Table of Elements Worksheet that is partially filled with atomic numbers, but the element names, symbols, and other details (like usage or group information) are missing. The goal of this worksheet is to fill in the missing information for each element based on its position in the periodic table.

Since I can't view images directly, I’ll help you solve this step-by-step based on how such worksheets typically work. Here's how to approach it:

---

🔍 Step 1: Understand the Structure

The periodic table is organized by:
- Atomic number (number of protons)
- Groups (columns) – e.g., Alkali Metals (Group 1), Halogens (Group 17), Noble Gases (Group 18)
- Periods (rows) – indicates electron shells

Each box has:
- Atomic number (top-left)
- Element symbol (center)
- Element name (bottom)
- Often, atomic mass and other info

In your worksheet, only atomic numbers are given. You need to fill in:
- Element symbol
- Element name
- Possibly group, period, usage, or properties

✔ Step 2: Use the Atomic Number to Identify the Element

Here’s a quick reference for common elements and their positions:

| Atomic Number | Symbol | Name | Group |
|---------------|--------|---------------|--------------|
| 1 | H | Hydrogen | 1 |
| 2 | He | Helium | 18 |
| 3 | Li | Lithium | 1 |
| 4 | Be | Beryllium | 2 |
| 5 | B | Boron | 13 |
| 6 | C | Carbon | 14 |
| 7 | N | Nitrogen | 15 |
| 8 | O | Oxygen | 16 |
| 9 | F | Fluorine | 17 |
| 10 | Ne | Neon | 18 |
| 11 | Na | Sodium | 1 |
| 12 | Mg | Magnesium | 2 |
| 13 | Al | Aluminum | 13 |
| 14 | Si | Silicon | 14 |
| 15 | P | Phosphorus | 15 |
| 16 | S | Sulfur | 16 |
| 17 | Cl | Chlorine | 17 |
| 18 | Ar | Argon | 18 |
| ... | ... | ... | ... |

You can continue filling in all boxes using this method.

🧩 Step 3: Fill in Based on Position

For example:

- Box at (1,1): Atomic Number 1 → H (Hydrogen)
- Group: 1 (Alkali Metal)
- Usage: Fuel, rocket propellant, part of water

- Box at (2,18): Atomic Number 2 → He (Helium)
- Group: 18 (Noble Gas)
- Usage: Balloons, cryogenics, welding

- Box at (4,1): Atomic Number 19 → K (Potassium)
- Group: 1 (Alkali Metal)
- Usage: Fertilizers, biological processes

- Box at (6,17): Atomic Number 35 → Br (Bromine)
- Group: 17 (Halogens)
- Usage: Flame retardants, pesticides

📌 Tips for Completing the Worksheet:

1. Use a Reference Periodic Table
Look up each atomic number online or from a printed chart.

2. Label Groups Correctly
- Group 1: Alkali Metals
- Group 2: Alkaline Earth Metals
- Groups 3–12: Transition Metals
- Group 13: Boron Group
- Group 14: Carbon Group
- Group 15: Nitrogen Group
- Group 16: Oxygen Group
- Group 17: Halogens
- Group 18: Noble Gases

3. Include Additional Details if Asked
For example:
- Iron (Fe): Used in steel, magnets, construction
- Oxygen (O): Essential for respiration
- Carbon (C): Basis of organic life, used in diamonds, graphite

4. Lanthanides & Actinides
- Lanthanides: Atoms 57–71 (e.g., La, Ce, Nd)
- Actinides: Atoms 89–103 (e.g., Ac, Th, U)

💡 Example Completed Box (Atomic Number 26):

| Atomic Number | Symbol | Name | Group | Usage |
|---------------|--------|----------|--------------|---------------------------|
| 26 | Fe | Iron | 8 (Transition Metal) | Steel production, blood hemoglobin |

✔ Final Advice:

To complete the worksheet:
1. Print or copy the table.
2. For each atomic number, write the correct symbol and name.
3. Add group/period labels.
4. Optionally include uses or properties.
