Worksheet for drawing Bohr diagrams with instructions and space for atomic numbers, element symbols, and electron shells.

The task involves creating Bohr diagrams for elements. A Bohr diagram is a visual representation of an atom's structure, showing the nucleus and the electrons in their respective energy levels (shells). Here’s how to solve this problem step by step:

Steps to Create a Bohr Diagram:

1. Identify the Element:
- You need to know which element you are drawing the Bohr diagram for. The atomic number will help identify the element.

2. Write the Atomic Number:
- Place the atomic number in the top-right corner of the box.

3. Draw the Nucleus:
- In the center of the diagram, draw a circle to represent the nucleus.
- Write the element symbol inside the nucleus.

4. Add Energy Levels (Shells):
- Electrons are arranged in shells around the nucleus.
- The first shell can hold up to 2 electrons.
- The second shell can hold up to 8 electrons.
- The third shell can hold up to 18 electrons, but for simplicity in middle school, we often stop at 8 electrons per shell beyond the first.

5. Place Electrons in Shells:
- Start filling electrons from the innermost shell outward.
- Follow the rule of maximum capacity for each shell.

Example: Let’s Draw a Bohr Diagram for Hydrogen (H)

#### Step-by-Step:
1. Atomic Number: Hydrogen has an atomic number of 1.
2. Nucleus: Draw a small circle in the center and write "H" inside it.
3. Electron Configuration: Hydrogen has 1 electron.
4. Energy Levels: Place the single electron in the first shell (which can hold up to 2 electrons).

#### Final Diagram for Hydrogen:
```
[1] (Atomic number)
H (Element symbol in the nucleus)
────
● (1 electron in the first shell)
```

General Guidelines for Other Elements:

- Helium (He): Atomic number = 2. Fill the first shell with 2 electrons.
- Lithium (Li): Atomic number = 3. Fill the first shell with 2 electrons, and place the remaining 1 electron in the second shell.
- Beryllium (Be): Atomic number = 4. Fill the first shell with 2 electrons, and place the remaining 2 electrons in the second shell.
- Carbon (C): Atomic number = 6. Fill the first shell with 2 electrons, and place the remaining 4 electrons in the second shell.
- Oxygen (O): Atomic number = 8. Fill the first shell with 2 electrons, and place the remaining 6 electrons in the second shell.
- Neon (Ne): Atomic number = 10. Fill the first shell with 2 electrons and the second shell with 8 electrons.

How to Proceed with the Task:

1. Choose elements or use the provided atomic numbers if given.
2. Follow the steps above to draw the Bohr diagram for each element.
3. Ensure that:
- The atomic number is written in the top-right corner.
- The element symbol is inside the nucleus.
- Electrons are correctly placed in their respective shells.
