It looks like you've uploaded an image of a
"Bohr Model Worksheet", which is a common chemistry assignment where students draw Bohr models (electron configurations) for various atoms based on their atomic number and electron arrangement.
Since I can't view or access images directly, I’ll need you to describe the content of the worksheet or list the elements/atoms that are included in the task. However, I can help you solve typical Bohr model problems if you provide:
1. The name or symbol of the element.
2. Any specific instructions (e.g., "draw the Bohr model for oxygen").
3. How many electrons or protons are given.

🔍 General Guide to Solving Bohr Model Problems:
Here’s how to draw a Bohr model step by step:
#### Step 1: Find the Atomic Number
- The atomic number tells you the number of
protons and, in a neutral atom, the number of
electrons.
- Example: Oxygen has atomic number 8 → 8 protons and 8 electrons.
#### Step 2: Determine Electron Shell Configuration
Electrons fill shells (energy levels) in order:
-
Shell 1 (n=1): holds up to 2 electrons
-
Shell 2 (n=2): holds up to 8 electrons
-
Shell 3 (n=3): holds up to 8 electrons (for most elements)
-
Shell 4 (n=4): holds up to 18, but we often simplify
Use the
order of filling: 2, 8, 8, 8...
#### Step 3: Draw the Model
- Draw a nucleus with the number of protons and neutrons (if known).
- Draw concentric circles around it for each shell.
- Place electrons (dots) in shells starting from the innermost.

✔ Example: Oxygen (O)
- Atomic number: 8 → 8 protons, 8 electrons
- Electron configuration: 2 in shell 1, 6 in shell 2
- Bohr diagram:
- Nucleus: 8p⁺, 8n⁰ (neutrons = mass number – protons; O-16 has 8 neutrons)
- First circle: 2 electrons
- Second circle: 6 electrons
