1. Explain using molecular orbital theory (MO) why Na2s a stable molecule.
2. Explain using MO why Ca2 (in its ground state) is not a stable molecule.
3. Explain using MO why Ca2 (in its first excited state) is a stable molecule.
Refer to the attached document for diagrams illustrating the solution.
1. According to molecular orbital theory, two atomic orbitals of almost similar in energy, shape combine to form two sets of molecular orbitals, low energy bonding orbital and high energy anti-bonding orbital. The stability of molecules can be explained using this theory
Consider Na2, the electronic configuration of sodium is 1s2 ...
This solution uses the molecular orbital theory to explain why certain molecules are stable or unstable.
