Molecular Orbital Theory for Diatomic Molecules
Quick fact
In molecular orbital theory, electrons are not assigned to individual bonds but are spread out over the whole molecule—this delocalization explains why O₂ is paramagnetic and why N₂ has an exceptionally strong triple bond.
Why this is interesting
You already know atoms stick together to form molecules, but have you ever wondered why oxygen gas is magnetic? The answer lies not in the atoms themselves, but in the invisible dance of electrons across the entire molecule.
