Question
**Title: Molecular Orbital Theory: Understanding Magnetism in I₂**

**Task:**

Complete the MO diagram (below) to determine if I₂ is paramagnetic or diamagnetic.

**Molecular Orbital (MO) Diagram:**

The diagram consists of molecular orbitals represented by horizontal lines. Electrons are indicated by arrows filling these orbitals.

From bottom to top, the orbitals are labeled as follows:

1. **σs**: Lowest energy non-bonding orbital where electrons first populate.
2. **σs***: Anti-bonding orbital, indicated by an asterisk (*).
3. **σp**: Bonding orbital formed from the combination of p-orbitals.
4. **πp**: Two degenerate π (pi) orbitals that allow lateral overlap.
5. **πp\***: Two degenerate anti-bonding pi orbitals, indicated by an asterisk (*).
6. **σp\***: Highest energy orbital, also anti-bonding, indicated by an asterisk (*).

**Question:**

Is I₂:

A) Paramagnetic: Has unpaired electrons.

B) Diamagnetic: All electrons are paired.

**Instruction:**

Analyze the filled molecular orbitals for unpaired electrons to determine the magnetic property of I₂. 

**Note:** For accurate results, fill the orbitals according to the electron configuration for I₂, considering the energy order and pauli exclusion principle.
