In `O_(2)` has double bond, `F_(2)` has single bond and `Ne_(2)` has no bond.

Explanation

To explain why \( O_2 \) has a double bond, \( F_2 \) has a single bond, and \( Ne_2 \) has no bond, we need to analyze the bond order of each molecule using molecular orbital theory. Here’s a step-by-step solution:

### Step 1: Understanding Bond Order
Bond order is defined as the difference between the number of bonding electrons and the number of antibonding electrons, divided by two. The formula for bond order is:

\[ \text{Bond Order} = \frac{1}{2} \left( N_b - N_a \right) \]
