We’re being asked to examine each of the orbitals and classify them as bonding, antibonding, or nonbonding then assign the correct number of electrons to the energy diagram. Lastly, examine if NH3 is stable using the info gathered.
Step 1: The total number of valence electrons present in NH3 is:
Group Valence Electrons
H 1A 3 × 1 e– = 3 e–
N 5A 1 × 5 e– = 5 e–
Total: 8 valence e–
The results of a molecular orbital calculation for NH3 are shown here. Examine each of the orbitals and classify them as bonding, antibonding, or nonbonding. Assign the correct number of electrons to the energy diagram. According to this energy diagram, is NH3 stable? Explain.
