Q: In molecular orbital theory, which of the following orbitals is filled first?
Solution:
According to the Aufbau principle, the σ2s orbital is filled first before any other orbitals.
Steps: 5
Show Steps
Step 1: Understand that molecular orbital theory explains how atomic orbitals combine to form molecular orbitals.
Step 2: Learn about the Aufbau principle, which states that electrons fill the lowest energy orbitals first.
Step 3: Identify the orbitals involved in molecular orbital theory, such as σ2s, σ2p, and others.
Step 4: Recognize that the σ2s orbital is the lowest energy orbital among the options given.
Step 5: Conclude that according to the Aufbau principle, the σ2s orbital is filled first before any other orbitals.
