1. Determine the Atomic Number:
* Fluorine (F) has an atomic number of 9. This means it has 9 protons and 9 electrons.
2. Draw the Nucleus:
* Draw a large circle in the center to represent the nucleus.
* Inside the circle, write the number of protons, which is 9.
3. Draw the Electron Shells:
* First Shell (K Shell): Draw a smaller circle around the nucleus to represent the first electron shell. Place 2 dots (representing electrons) within this circle.
* Second Shell (L Shell): Draw another circle around the first shell. Place 7 dots (representing electrons) within this circle.
The completed diagram looks like this:
```

Key Points:
* Protons: Located in the nucleus, they determine the element's identity.
* Neutrons: Also in the nucleus, they contribute to the atom's mass. Fluorine has 10 neutrons, but they aren't shown in the Bohr-Rutherford model.
* Electrons: Orbit the nucleus in shells. The first shell can hold a maximum of 2 electrons, and the second shell can hold a maximum of 8.
