Chemistry - CHEMICAL BONDING Question with Solution | TestHub

O₂²⁻ → all electrons paired → Diamagnetic → (4)

CO → 14 electrons, isoelectronic with N₂ → Bond order 3, diamagnetic → (1, 4)

ON⁺ → 14 electrons, unpaired → Paramagnetic, isoelectronic with N₂⁺ → (1, 4)

He₂⁺ → 2, 3 (Paramagnetic, bond order 0.5) → (2 ,3)
