This would be stable, in that it has lower net electron energy than the two initial atoms. It is not as stable as something with a higher bond order for a similar MO diagram (ex. H2)

How many electrons would be filled in each 2p orbital? SOLUTION
Determine the complete electron configuration of nitrogen. SOLUTION
If you made some mistakes or want to practice more, review the concepts that gave you trouble and work on this extra problem. If you're good, move to the problem below ;)
Problem 1.2: Valence Bond (VB) Theory
Draw the VB theory orbital overlap for HCl. SOLUTION
Explain why a resulting bonding orbital is lower energy than an initial atomic orbital. SOLUTION
If you made some mistakes or want to practice more, review the concepts that gave you trouble and work on this extra problem. If you're good, move to the problem below ;)
Problem 1.3: Molecular Orbital (MO) Theory
Draw the MOs that result from the combination of a hydrogen atom and a helium atom. SOLUTION
Draw the MO diagram for H-He. Fill in the electrons, determine bond order, and whether or not this would be a stable molecule. SOLUTION
