Question

complete the model of a neon atom by dragging and dropping electrons onto the rings that represent each shell.

Explanation:

To complete the neon atom model:

1. Recall neon's atomic number is 10, so it has 10 electrons.
2. Electron shell rules: First shell (n=1) holds max 2 electrons, second shell (n=2) holds max 8 electrons.
3. For neon, fill first shell with 2 electrons, then second shell with 8 electrons (2 + 8 = 10, matching atomic number).

Answer:

• First electron shell (innermost): Place 2 electrons.
• Second electron shell (outer): Place 8 electrons.
