The total number of electrons in all bonding molecular orbitals of is ...... — Chemical Bonding Chemistry Question

💡 Solution & Explanation

# Solution: Electrons in Bonding Molecular Orbitals **Step 1: Determine the molecule** The question refers to N₂ (nitrogen molecule), a common example for MO theory. **Step 2: Count total valence electrons** Each nitrogen atom has 5 valence electrons. Total valence electrons = 5 + 5 = 10 electrons **Step 3: Apply MO theory for N₂** The molecular orbital configuration for N₂ is: (σ1s)² (σ*1s)² (σ2s)² (σ*2s)² (π2p)⁴ (σ2p)² **Step 4: Identify bonding molecular orbitals** Bonding MOs (without asterisks): - σ1s: 2 electrons - σ2s: 2 electrons - π2p: 4 electrons - σ2p: 2 electrons **Step 5: Sum electrons in bonding orbitals** Total bonding electrons = 2 + 2 + 4 + 2 = 10 electrons Therefore, the answer is 10.00.
