Elements with atomic numbers 7, 8, 9 and 10 are gases. Under similar conditions, which gas has highest rate of diffusion? Why?

Explanation

To solve the question of which gas among the elements with atomic numbers 7 (Nitrogen), 8 (Oxygen), 9 (Fluorine), and 10 (Neon) has the highest rate of diffusion, we can follow these steps:

### Step 1: Identify the Gases
The elements with atomic numbers 7, 8, 9, and 10 are:
- Atomic number 7: Nitrogen (N₂)
- Atomic number 8: Oxygen (O₂)
- Atomic number 9: Fluorine (F₂)
- Atomic number 10: Neon (Ne)
