Which of the following molecular orbitals is lower in energy than the 2p atomic orbitals?

Which of the following molecular orbitals is lower in energy than the 2p atomic orbitals?

Step 1: Understand that molecular orbitals are formed from the combination of atomic orbitals.
Step 2: Recognize that atomic orbitals include s and p orbitals, such as 2s and 2p.
Step 3: Know that in general, the energy levels of molecular orbitals can be compared to atomic orbitals.
Step 4: Identify that σ2s is a molecular orbital formed from the combination of 2s atomic orbitals.
Step 5: Remember that σ2s is lower in energy than the 2p atomic orbitals because it is more stable.
Step 6: Conclude that σ2s is the correct answer to the question.
