Q: What is the molecular orbital configuration of F2?

Solution: The correct configuration for F2 is (σ1s)²(σ*1s)²(σ2s)²(σ*2s)²(σ2p)²(π2p)⁴(π*2p)².

Steps: 11

Step 1: Identify the total number of electrons in F2. Each fluorine atom has 7 electrons, so F2 has 14 electrons in total.
Step 2: Write down the order of molecular orbitals for diatomic molecules: σ1s, σ*1s, σ2s, σ*2s, σ2p, π2p, π*2p.
Step 3: Fill the molecular orbitals with the 14 electrons, starting from the lowest energy level to the highest.
Step 4: Fill the σ1s orbital with 2 electrons: (σ1s)².
Step 5: Fill the σ*1s orbital with 2 electrons: (σ*1s)².
Step 6: Fill the σ2s orbital with 2 electrons: (σ2s)².
Step 7: Fill the σ*2s orbital with 2 electrons: (σ*2s)².
Step 8: Fill the σ2p orbital with 2 electrons: (σ2p)².
Step 9: Fill the π2p orbitals with 4 electrons (2 in each): (π2p)⁴.
Step 10: Fill the π*2p orbital with 2 electrons: (π*2p)².
Step 11: Combine all the filled orbitals to write the final molecular orbital configuration.
