**Molecular Orbital Energy Diagram Analysis for Be₂⁻ Ion**
**Objective:**
Determine the bond order for the negative ion Be₂⁻ using the molecular orbital energy diagram.
**Diagram Analysis:**
- **MO Diagram of Be₂⁻:**
- Left side: Atomic orbitals of beryllium atom "A".
- Right side: Atomic orbitals of beryllium ion "B⁻".
- Middle: Molecular orbitals (MO's).
- **Energy Levels:**
- The diagram has shown the following molecular orbitals:
- Bonding orbitals: σ2p and π2p
- Antibonding orbitals: π*2p and σ*2p
**Data Input Table:**
1. **Number of Bonding Valence Electrons:** [Input required]
2. **Number of Antibonding Valence Electrons:** [Input required]
3. **Be₂⁻ Bond Order:** [Input required]
**Bond Order Formula:**
Bond Order = (Number of Bonding Electrons - Number of Antibonding Electrons) / 2
**Interpretation of Bond Order:**
- A. Single bond
- B. Double bond
- C. Triple bond
- D. Half of a bond
- E. Between a single and double bond
- F. Between a double and triple bond
- G. No bond, Be₂⁻ does not form
**Instructions:**
Use the provided MO diagram and the bond order formula to complete the table and determine which of the interpretations (A-G) corresponds to the calculated bond order.
