How do I draw a molecular orbital diagram online?

Enter the molecule or ion, describe the orbital ordering, electron count, labels, and bond order you need, choose an aspect ratio, then generate and review the diagram.

Can it draw MO diagrams for N2, O2, CO, and F2?

Yes. You can request common molecular orbital diagrams such as N2, O2, CO, F2, H2, C2, CN-, or N2-, then review the orbital ordering and electron occupancy.

Does it show bond order, sigma and pi orbitals, and s-p mixing?

Yes. Include bond order, sigma orbitals, pi orbitals, sigma star or pi star antibonding orbitals, s-p mixing, HOMO/LUMO, and electron arrows in your prompt.

Can I make a diagram from electron configuration?

Yes. Provide the ground-state electron configuration or valence electron count, then specify the molecule, ion charge, orbital ordering, and labels to include.

Can I use the diagram for chemistry class or homework?

Yes. The generated PNG can be used in class materials, homework, worksheets, slides, or study notes after reviewing electron counts, labels, and bond order.

What is a molecular orbital diagram?

A molecular orbital diagram is an energy-level diagram that shows how atomic orbitals combine into bonding and antibonding molecular orbitals. It helps explain electron configuration, bond order, magnetic behavior, HOMO/LUMO, and orbital ordering in molecules such as N2, O2, CO, F2, H2, and C2.

Parts of a molecular orbital diagram

Atomic orbitals appear on the left and right, usually grouped by atom and energy level.
Molecular orbitals sit in the center as bonding, antibonding, sigma, and pi levels.
Electron arrows show occupancy, pairing, unpaired electrons, and magnetic behavior.
The energy axis and correlation lines explain how atomic orbitals combine.
Bond order, HOMO/LUMO labels, s-p mixing, and notes help students check the result.

Where molecular orbital diagrams are used

General chemistry and inorganic chemistry lessons about bonding and electron configuration.
MO diagram homework, worksheets, study guides, classroom slides, and exam review materials.
Lab reports and teaching figures that compare bond order, paramagnetism, and orbital filling.
