The worksheet titled
"Creating Atom" asks you to draw the electron configurations of four different atoms:
Oxygen, Sulfur, Carbon, and Magnesium. Each atom is represented by a set of concentric circles, which represent
electron shells (energy levels) around the nucleus.
To complete this task, we need to:
1. Know the
atomic number (number of protons/electrons) for each element.
2. Place electrons in the correct energy levels following the
electron configuration rules:
- The first shell holds up to 2 electrons.
- The second shell holds up to 8 electrons.
- The third shell holds up to 8 electrons (for these elements).
3. Draw dots (representing electrons) on the circles accordingly.
Let’s go through each one step-by-step.
---
🔹 1. Oxygen (O)
-
Atomic Number: 8 → 8 electrons
-
Electron Configuration: 2, 6
- First shell (inner circle): 2 electrons
- Second shell (outer circle): 6 electrons
✔ Draw:
- 2 dots in the inner circle
- 6 dots in the outer circle
---
🔹 2. Sulfur (S)
-
Atomic Number: 16 → 16 electrons
-
Electron Configuration: 2, 8, 6
- First shell: 2 electrons
- Second shell: 8 electrons
- Third shell: 6 electrons
✔ Draw:
- 2 dots in the innermost circle
- 8 dots in the middle circle
- 6 dots in the outermost circle
---
🔹 3. Carbon (C)
-
Atomic Number: 6 → 6 electrons
-
Electron Configuration: 2, 4
- First shell: 2 electrons
- Second shell: 4 electrons
✔ Draw:
- 2 dots in the inner circle
- 4 dots in the outer circle
---
🔹 4. Magnesium (Mg)
-
Atomic Number: 12 → 12 electrons
-
Electron Configuration: 2, 8, 2
- First shell: 2 electrons
- Second shell: 8 electrons
- Third shell: 2 electrons
✔ Draw:
- 2 dots in the innermost circle
- 8 dots in the middle circle
- 2 dots in the outermost circle

✔ Final Answer Summary (How to Fill the Worksheet):
| Element | Electron Shells (from inside out) |
|-------------|-----------------------------------|
|
Oxygen | 2, 6 |
|
Sulfur | 2, 8, 6 |
|
Carbon | 2, 4 |
|
Magnesium| 2, 8, 2 |
> 🖋️
Instructions for drawing:
> - Use small dots to represent electrons.
> - Distribute them evenly around each circle.
> - Make sure each shell has the correct number of electrons.

💡 Tips:
- The
nucleus (protons and neutrons) is in the center — but it's not required to draw here; just focus on electrons.
- This model is called the
Bohr model, which simplifies atomic structure for learning purposes.
